3 | INTRODUCTION Welcome to our world. We would like to invite you on a tour of some of the real estate developments that we are very proud of. Together with our partners, such as architects, engineers, investors and municipalities, we have been able to acquire the go-ahead for projects that will change the look of cities and the lives of their users. Porten Development has been focusing on office and residential projects since 2010. Although we have an international scope, we are mainly active in Sweden and the Netherlands, where we focus on providing the end-users of our real estate developments with an architectural attractive and socially coherent environment in which there is space for living, working and leisure. Naturally, we aim at meeting the stringent demands of sustainability, energy concepts and safety we value so highly. Therefore, we cooperate with local authorities, investors and partners who are all specialists in their field. This portfolio book offers an insight into some of the developments that we would like to think of as our legacy. It is also an introduction to our team and some of our most valued partners. TOGETHER, WE ARE BUILDING A BETTER FUTURE PORTEN DEVELOPMENT

PORTEN DEVELOPMENT 7 | Leiden, The Hague, Rotterdam, Utrecht and Zaandam), but we have an international scope. Inspired by climate challenges, we wish to develop state-of-the-art, sustainable, and therefore zero-energy buildings and areas where people can thrive. We invest in carbon neutral solutions, but also in next generation air and lighting technologies. We believe it pays to invest in the future today, since we feel that this is the only way forward. Climate issues can be solved. Together. For this, teamwork is essential. That is why we only work with partners that are pure specialists. Knowing the market A sustainable future is a future in which our children can happily live and play. A future in which everyone can enjoy an optimal worklife balance. A future in which our elderly citizens have a comfortable place to retire, within the very community to which they devoted their working lives. In short: a future for all of us. Therefore, Porten has been focusing on office and residential projects since 2010, including apartments, student housing, and extended-stay hotels. We have been working mainly in Sweden and the Netherlands, particularly within the great Randstad metropolis (Amsterdam, Haarlem, and understanding investors’ demands, a clear view of risk-return, combined with an in-depth technical and design know-how are crucial, too. Most important of all is a shared ambition which drives all parties contributing to the project. In fact, our name says it all. Porten is the Swedish word for ‘gateway’, and we commit ourselves every day to be the gateway to a better future. OUR STORY ‘WE WISH TO DEVELOP STATE-OF-THE-ART, SUSTAINABLE LIVING AREAS WHERE PEOPLE CAN THRIVE’ Porten Development is a 21st century ‘niche’ developer. Our motto: the future is ours. Using our more than 25 years of experience, and planning at least 5 years ahead, we aim to make a tailor-made contribution to a sustainable future.

PORTEN DEVELOPMENT 9 | SUSTAINABILITY At Porten Development, we look at sustainability as an essential part of property development. That is why it is in the DNA of all our projects. A building is always part of a larger context. And we are aware of our social responsibility. We consider technical sustainability, and the impact on the environment, we strive for innovation and the inclusion of nature in our projects, and we implement climate adaptation. Moreover, we have been committing ourselves to the Sustainable Development Goals® since 2019. INNOVATIVE SOLUTIONS Besides creating a functional building, we also have to deal with possible issues such as flooding, heat stress, nitrogen emissions, biodiversity, drought, wind nuisance and high noise levels. All these challenges have to be met by a wellthought-out design that seamlessly connects to its immediate surroundings. On the one hand, through smart installations and engineering; on the other hand, by emphasizing the importance of natureinclusivity and climate adaptivity. This integral approach to site ecology, architecture and landscape defines our way of thinking. COOPERATION Realizing a residential area, a hotel or an office building involves planning, patience and people. The lead time of a real estate project can easily take a decade. A solid relationship with municipalities, investors and building partners is therefore essential. We pride ourselves in finding exactly the right partners: architects, building contractors, and innovative appliance designers. Each of them being a specialist in their field, with the knowledge, skills and experience needed to develop not only a building, but an entire community. PROFITABLE INVESTMENTS Let’s be clear, every development must be profitable for all parties involved. Luckily, we have an eye for interesting opportunities. We know the market and understand investors’ demands, having a clear view of risk-return, combined with an in-depth technical and design know-how. By working with the best partners, we are able to deliver truly sustainable profitability to our investors. Naturally, our small, dedicated team and low overhead make a valuable contribution. At present, the market for residential developments in the Netherlands is firm, optimistic and growing. COMMUNITY BUILDING We aim to build socially coherent communities. In our projects, we always try to include as many user groups as possible. A solid social network makes a fine neighborhood, which, in turn, results in happier and healthier living for all those involved. That is why we build real estate that offers room for social interaction and care for the elderly, with an interplay of gardens, shopping centers, and care facilities, and that also complies with the stringent regulations with regards to safety, adaptability and life cycle durability. That’s compassionate building. KEY WORDS We see real estate development as a constant search for the optimal spatial implementation of living, working and recreation, whereby the impact on the environment is limited, the experience of residents, users, and passers-by is optimized, and a feasible business case is created, as well.
PORTEN DEVELOPMENT 13 | RESIDENTIAL What makes a house a happy home? Its design? The level of comfort? A little garden or a balcony? Or the people you meet when you step outside? At Porten, we think all of the above. Why choose when you can have it all?
WESTFLANK NOORD - UTRECHT The 90-meter residential tower with a shared roof-top offers an exceptional view over the old city of Utrecht.
16 | PORTEN DEVELOPMENT WESTFLANK NOORD UTRECHT Here, next to the recently built Utrecht City Hall (SKU, Stadskantoor Utrecht) and basically at Utrecht Central Station, the busiest train hub in the Netherlands, a 90-meter residential tower will host 270 dwellings. On the roof, a common roof-top for all residents has been created with an exceptional view over the old town of Utrecht and its surroundings. The project marks the beginning of the new Sijpesteijnkade with commercial functions on the ground floor and apartments above. A wide staircase connects Sijpesteijnkade, the Forum quay, the upper plateau, which is on the same level as Utrecht Central Station and the entrance to SKU. An old listed building, built in 1912, has been integrated in the design. It keeps its own entrance on the quay, and will now also be accessible through the new entrance hall. Given the noise-sensitive area of the project, a facade was designed that will cope with all different acoustics coming from the neighbourhood (rail tracks next to the project, among others). OZ have designed an appealing city center high-rise residential tower, which will serve as a landmark for this buzzing location. Westflank Noord 3A has jointly been developed together with Wessels Zeist and sold to Amvest Residential Core Fund.

19 | PORTEN DEVELOPMENT OZ is a full service design company which founder Wouter Zaaijer characterizes as ‘a practice of modernist architects’: “The projects range from single buildings to whole urban areas. Our design language is functional, we make spaces for people. Sustainability has always been a major factor in this, therefore we are founding partner of DGBC, the Dutch Green Building Council.” SHARED VALUES “What we like about Porten Development is that we see a genuine interest in the values we hold dear. Architects think about designs, functionality, and all the things that account for happy living. It is nice to meet a developer that is not only calculating the profits, but who also wants to build beautiful and qualitatively good buildings for people. In this we understand and respect each other.” Porten and OZ have recently been working on the Westflank Noord 3A/ Van Sijpesteijnkade project in the center of Utrecht. Zaaijer: “Here, we have realized a 90-meter high-rise with 270 small surface dwellings with a common rooftop, aimed at young professionals, singles and starting families. Sustainability is the key word, therefore we use underground heat and cold storage, among other installations. Since it is virtually on top of Utrecht Central Station, noise reduction was our main challenge. Luckily, we have vast experience in developing smart solutions and a large network of specialized engineers to tackle those issues.” HAPPY NEIGHBORHOOD In Weesp, the two companies cooperate on a residential project together with other developers. Zaaijer: “Here, we want to create the ultimate livable neighborhood. However, the area is full of empty buildings now, so it is not as straightforward as building from scratch. The municipality of Weesp requires 30% social housing, which has to be incorporated in the bigger plan. Furthermore, we are planning meeting areas, like an inner garden, and work spaces. Moreover, cars will be banned from the streets. This is what we like doing, completing the intricate puzzle that results in a really beautiful living environment.” WOUTER ZAAIJER OZ - INTERVIEW - Architects play a very important role in the development of properties. They have to reduce a broad range of questions to a single, workable and livable concept, taking both municipal requirements and investor demands into account. OZ architect Wouter Zaaijer loves this process: ‘It’s part of our DNA.’ ‘I BELIEVE IN COMMUNITIES THAT ARE BUILT AROUND PUBLIC TRANSPORT HUBS’

21 | RESIDENTIAL HOUTHAVENKADE - ZAANDAM This project will be the connecting link between Ducra harbour, Het Eiland, and the Russische Buurt; a beautiful new entrance to the center of Zaandam.
22 | PORTEN DEVELOPMENT On 26 February 2020 Gemeente Zaanstad concluded the agreement for the Houthavenkade with Porten Development B.V. and Bot Bouw B.V. In May 2022 Ten Brinke Bouw B.V. replaced Bot Bouw B.V. and became joint venture partner with Porten Development B.V. The Houthavenkade project in Zaandam is making way for a sustainable residential area with 710 homes. The project will accommodate 30% of social housing, 20% mid-rental units and 50% private sector rental apartments. It will be the connecting link between Ducra harbour, Het Eiland, and the Russische Buurt, and forms a beautiful new entrance to the center of Zaandam. The urban plan for this new part of Zaandam is a co-creation between VAN AKEN and supervisor Sjoerd Soeters. VAN AKEN designed all individual buildings, inspired by the port history and the industrial heritage of the ‘Zaanse Schans’, as well as the interaction with the water. The core of the project is the ‘water square’ in the center, with adjacent hospitality facilities as a meeting point. An extra bridge to the Russische Buurt will be added. There will be a small harbour for passing recreational boats, adjacent to catering establishments and furnished with stairs. Green public space between the houses reinforces the impression of sustainability. Houthavenkade is within walking distance of Zaandam station, city hall and the largely traffic-free city center of Zaandam. Residents park under the buildings or use one of the shared cars.

24 | PORTEN DEVELOPMENT ‘ PEOPLE ENJOY LIVING IN A DIVERSE NEIGHBORHOOD THAT HAS ITS OWN IDENTITY’ Rochdale is facing challenges as the housing market in het Amsterdam region stagnates. Everyone has the right to a home, but the demand for affordable housing far exceeds supply. Eric Nagengast, director Real Estate at Rochdale: “We are always looking to develop new housing opportunities, and for partners who can do this for us. Our experience with Porten has been great. We are now actively looking to acquire new sites together, where we can develop the houses we need so urgently.” FAST DECISION-MAKERS “What we like most about Porten is their fast way of thinking. They are very resultoriented and react immediately if we have a question or an idea. We are quick decisionmakers ourselves, too. To us this proves their commitment to our partnership. I feel we speak the same language. This is very different from the large institutional parties we sometimes work with. Moreover, we are both very flexible. If you want to make a deal you have to give each other space, it is a matter of trust. The people at Porten understand this, and our collaboration really gave us a taste for more.” Rochdale wants to expand in the Zaanstad area, which faces a large housing shortage, especially in social housing. “We complement each other. We have the experience in dealing with municipalities. Porten has their own property assets and the contacts to acquire more. And since we are involved from an earlier stage now, we can make sure the demands of our renters will be met. For Porten this is interesting, too. They will know in an early stage what financial room we have and what the technical demands will be.” COSMOPOLITAN ZAANSTAD The Houthavenkade project has turned out especially satisfactory. Nagengast: “To us, this project symbolizes the transformation of Zaanstad, from an industrial area with workers’ homes to a cosmopolitan extension of Amsterdam. Porten has managed to find architects and builders that maintained the unique identity of the neighborhood, even though it is a high-rise urban project. We always aim to ensure a neighborhood’s livability and believe that everyone should be able to participate fully in society. Houthavenkade is certainly a place where people can live safely and comfortably. I am sure we will develop many more durable projects like this together. I am looking forward to it.” ERIC NAGENGAST ROCHDALE Housing corporation Rochdale is always looking to expand its portfolio of houses to meet its ambitions of tackling the housing shortage in the Amsterdam area. Porten Development offered them a collaboration in the Houthavenkade project in Zaanstad. Rochdale’s director of Real Estate Eric Nagengast highly values their partnership: “The Houthavenkade project is the doorway to more beautiful projects together.” - INTERVIEW -

28 | PORTEN DEVELOPMENT ONE MILKY WAY THE HAGUE The Binckhorst area in The Hague has always had an identity of ‘industrial, creative and a touch raw’. What used to be an industrial area is now changing into an innovative and sustainable residential/ working area with trendy restaurants and bars at the port. One MilkyWay will be located here. Porten and VORM jointly develop this mixed project with a 70-meter high residential tower that will accommodate 270 dwellings. On the roof, a common roof-top for all residents has been created with an exceptional view over the city. High-end office space will be allocated on the lower levels above the commercial spaces on the ground floor. OZ has designed this tempting city center high-rise, which is easily recognisable as a landmark, even from a great distance. The project adds up to approximately 25,000 m² of which 27% is commercial/ office space. SPECIFICATIONS GROSS FLOOR AREA APPROX. 25,000 M2 PROGRAM 270 DWELLINGS ARCHITECT OZ

30 | PORTEN DEVELOPMENT MOTORKADE AMSTERDAM Motorkade is part of the Hamerstraat area in North Amsterdam, one metro stop away from Amsterdam Central Station on the new North/ South metro line. The Hamerstraat area is currently subject to extensive discussions between the City of Amsterdam and the stakeholders attached to the area. In addition to the new North/South line, there will be at least one bridge for pedestrians and cyclists over the IJ River to connect North Amsterdam with the city center. The landing on the north side of the bridge will be a mere 100 meters away from the project. The design of the new apartment building will have a robust appearance and an industrial atmosphere. This will be achieved through a specific choice of materials and powerful detailing. In this way, the building seamlessly connects to the signature of the original neighborhood. Porten bought the plot in 2015 and signed a cooperation agreement with VORM in 2016. The design – created by ZZDP Architects – follows a contemporary line, reflecting the new, modern vision of North Amsterdam. Motorkade is one of the few freehold land properties in Amsterdam.

34 | PORTEN DEVELOPMENT CRUQUIUSWEG AMSTERDAM Cruquiusweg 140/142 is a joint development between Porten and VORM in close cooperation with the City of Amsterdam. The project is a waterfront location along the Amsterdam-Rijn Canal on the growing Cruquius Peninsula in East Amsterdam. The original Cruquiusweg was built in 1879. It was named after Nicolaus Samuelis Cruquius (1678-1754), lauded land surveyor and hydraulic engineer. The design of the project, by Dam & Partners Architects, reflects the atmosphere of the docklands, harbours and warehouses, but does so in a modern and timeless manner. It seldom happens that a building’s design fits in so seamlessly with its historical link and location as is achieved at Cruquiusweg. The project consists of three buildings constructed in brick, all linked together with an underground car park. In order to reinforce the impression of docklands, harbour and warehouses, a number of bridges have been built between the buildings. Large balconies add value to the 149 apartments. CBRE Global Investors has acquired the entire project.

36 | PORTEN DEVELOPMENT Porten is developing a site with approximately 150 homes and a church at Hettenheuvelweg. The project is part of the development plan for the Hessenbergweg area in Amsterdam South-East. Here, a pleasant mix of living and working will be realized. The aim is to create a vibrant urban area with around 2,500 mixed types of dwellings, a school, child care facilities, restaurants, a supermarket, a church and 12,000 m2 of working space. In the center of the new neighborhood a green park will be created in which people can relax, play and have a picknick. The development is central to the new city district Amstel III, where living, working and recreation come together, mirroring the sociability of the older Amsterdam city neighborhoods.

38 | PORTEN DEVELOPMENT C.J. VAN HOUTENLAAN WEESP The Cacaokwartier (Cacao Quarter) is also known as the Van Houten Industrial Park, and it is the oldest business park in Weesp. The Van Houten family settled here in 1850 and built up a chocolate empire, which provided many jobs, making chocolate factory Van Houten the pride of Weesp. However, in 1971 the curtain fell on the factory and the site was taken over by the pharmaceutical industry. Today, many offices on the business park are empty. This level of vacancy contrasts sharply with the adjacent lively historic centre of Weesp. The Weesp municipality wishes for the Cacaokwartier to become a high-quality residential area, while retaining its own identity. A vibrant district with its own character in which a significant part of Weesp’s large housing needs will be met. There will be room for a diversity of target groups: starters, young people and the elderly. This translates into smaller homes that provide quality housing. Porten is developing together with Ten Brinke a mixed project in the “Cacao” area with dwellings and offices. A 6-floor residential tower will encompass
39 | RESIDENTIAL Approximately 170 dwellings. Part of these Will accommodate elderly people in need of care. The entire neighborhood will be provided with a well laid out public space with lots of greenery and no cars or bikes (built-in parking). Interior gardens will provide tranquility and recreational space. In the Cacaokwartier, the mobility transition will be stimulated in order to limit the number of transport movements and related CO2 emissions. Finally, the transparent building blocks provide vistas and a sense of security. This is what we call friendly architecture.

40 | PORTEN DEVELOPMENT WASA STUDENT VILLAGE AMSTERDAM In December 2017, WASA Student Village (WASA) in Amsterdam Sloterdijk, opposite the Orly Centre, was opened after a record building time of twenty weeks. More and more, the Station Sloterdijk area is becoming a residential district. Amidst offices and hotels, the new WASA Student Village offers space for 358 students, spread over 7 buildings. The residences are temporary, and the set-up of the student housing is village-like. By using wooden panels for the facades in three different motifs, a sense of variation was created which enhances the public area around the apartments, which also includes terraces. Porten, together with Camelot Europe and Jan Snel, and in close collaboration with the City of Amsterdam, were the driving force behind this project. By signing a cooperation agreement, the University of Amsterdam (UvA) and the University of Applied Sciences of Amsterdam (Hogeschool van Amsterdam, HvA) became important supporters.

44 | PORTEN DEVELOPMENT PROF. J.H. BAVINCKLAAN AMSTELVEEN The ‘Kronenburg Uilenstede’ area is currently subject to an extensive urban development. The municipality has given priority to this new part of Amstelveen. Dam & Partners made the design for a future-proof multi-tenant office building. The design is an example of a new office typology, in which the public domain runs through the building. Demand is growing for a new type of office, in which there is a balance between office space, (leasable) workplaces, wellbeing, and health. The multi-tenant offices of the future will focus more and more on a healthy and safety environment. According to Dam & Partners, such buildings have large floor areas and communal facilities, which are open to the immediate vicinity. They are therefore being designed specifically for use by large and smaller companies at the same time. The building thus becomes an organic network, within which companies can share knowledge, collaborate, and (continue to) grow.

48 | PORTEN DEVELOPMENT ORLY CENTRE AMSTERDAM The Orly Centre was developed as a comprehensive office complex in Amsterdam Sloterdijk, in close proximity to the station with the same name. Orly consists of two attached buildings. The front and the exterior walls are built in traditional red brickwork. Both Orly N1 (2002) and Orly N2 (2009) have been Developed (by the Porten management, but in a different legal entity) for the account of IG Immobilien Gmbh, Vienna (100% subsidiary of ÖNB, Austrian National Bank), as the executive partner. Orly N1 and Orly N2 have been transformed into a complex of hotels, short-stay apartments, restaurants and cafés. Orly N1 has become the Mercure hotel (2016) and Orly N2 an extended-stay hotel under the direction of Amsterdam City Apartments (2016-2017). The convenience of the extensive public transport links at Amsterdam Sloterdijk station guarantees a substantial occupancy rate. The design of the buildings carefully accounted for a height difference of approximately five meters between Radarweg and Barajasweg in an ingenious way. The building’s facade is composed of red masonry, white concrete accents and two-storey window openings. The frames of the window penings are tucked behind the masonry, providing the deep office floors with as much daylight as possible. On the two corners of Barajasweg, both the main entrance and the entrance to the parking garage are accentuated upwards by white columns between which large glass facades have been designed for the entrance hall.

54 | PORTEN DEVELOPMENT Amsterdam Houthaven is an idyllic location with a captivating history. In former years, a visitor of the Houthaven would see floating timber as far as the eye could see. Today, the oldest dock of Amsterdam is being transformed into a modern residential district fit for the 21st century. In June 2016 Porten Development, together with VORM Ontwikkeling, won the public tendering procedure for Houthavens 3B. On the third island, Reval Isle of Houthavens (3B), the LIFE building is under construction. Being a waterfront location on the banks of the IJ River, on a green and sustainable island, where the panoramic view changes color every day, LIFE is the ultimate mixture of urban development. It combines intramural care, care for elderly people, a pharmacy and catering services, social housing, free rental apartments, and private apartments. The building by VAN AKEN architecten, a timeless example of the Amsterdam School architecture style, comprises beautiful and stylish apartments, two-storey maisonettes, boutique apartments, and splendid penthouses. LIFE also comes with an underground car park within the building, a spacious, covered bicycle storage facility, storage facilities for the apartments, and a green, private inner court yard for residents. In order to meet the most stringent energy label demands, solar panels are placed on the roof. LIFE has been bought by Bouwinvest Health Care fund, Habion and private investors. LIFE AMSTERDAM

56 | PORTEN DEVELOPMENT ‘THE ACTUAL LIFE BUILDING IS EVEN MORE BEAUTIFUL THAN IN THE RENDER IMAGES’ By the year 2040 there will be 2.5 million people over the age of 75 in the Netherlands. Erwin Drenth (director Bouwinvest Real Estate Investors): “Many of them will be stuck in houses that are no longer suitable for them: too big, with stairs, in a neighborhood where they feel unconnected. Plus, the number of potential informal carers per person will have halved by that time. Therefore, developing senior housing and residential care properties now is a necessity, not a luxury.” CARE PHILOSOPHY Enter the LIFE building. Drenth: “Porten Development saw the opportunity and we stepped in. We are really proud of our cooperation: all homes are single-level without thresholds, there are sufficient meeting spaces and facilities aimed at forestalling the need for care. Not only with a pharmacy, physiotherapist, district nursing, domestic help and a nursery home, but we also work with hostesses who organize activities. These ladies are highly appreciated by the residents.” Moreover, LIFE’s population comprises many LHBTIQ+ oriented people. “Creating an inclusive community in which you can age in a vital way is what we have always aimed for.” The project has been a profitable investment, too. Care property has seen a growing demand lately, especially by pension funds. Drenth: “This ‘Impact Investing’ aims for more than just financial profits. Investing in future-proof and sustainable houses has a double advantage: it gets the housing market moving again, and it has a positive impact on the general costs for elderly care, because formal care is postponed. Plus, it is a rather stable investment, which is valued immensely by pension funds.” OPPORTUNITIES The informal attitude of the developers at Porten was agreeable and productive. Drenth: “Johan and Richard are sympathetic, outgoing personalities. They are real entrepreneurs who think in opportunities and possibilities, not in obstacles. When we first worked together in 2015, the fund was just starting up. However, given their previous experience with Bouwinvest, they put their trust in us and were not afraid to jump in at the deep end. This has resulted in a beautiful building, even better than in the render images. The city of Amsterdam now even wants to use it as an example for future tenders!” ERWIN DRENTH BOUWINVEST HEALTHCARE Porten Development found a solid and inspired partner in the Bouwinvest Healthcare Fund for the funding of the Houthaven LIFE project in Amsterdam. Erwin Drenth of Bouwinvest: “This kind of project is exactly what we aim for with our fund. Creating a living environment that enables seniors to continue living independently for as long as possible.” - INTERVIEW -

We have clients ranging from high-tech industrial companies to psycho-geriatric care homes and amusement park Efteling. So, we literally make dreams come true! Porten Development has the same attitude towards stepping out of their comfort zone.” HOUTHAVEN LIFE PROJECT IN AMSTERDAM The first project VAN AKEN and Porten took on together was the Houthaven project in Amsterdam, also called LIFE. ”The municipality of Amsterdam wanted a plan that would do justice to the history of this neighborhood. The Spaarndammerbuurt had always been a working-class district. This is why we were required to include a large part of social housing. We added high-level care units and intramural care facilities, since we believe inclusive building is indispensable for a livable future.” HOUTHAVENKADE PROJECT IN ZAANDAM For the Houthavenkade project in Zaandam, the boundaries of the two companies’ comfort zone were definitely pushed. “Here, we are rebuilding an industrial zone into a sustainable residential area, with 710 homes, 40 private sector and 670 rental properties, of which 30% social housing and 20% mid-market rental houses. We have developed a wonderful plan. We even designed a new marina for boats and along the waterside there will be cafes and restaurants: they form the heart of the neighborhood. The local community is excited and welcoming to the new plan.” FUTURE-PROOF BUILDING The two companies find each other in their desire to leave something tangible and valuable behind for future generations. “For both our companies the client and his neighborhood are the most important factors. Johan loves to puzzle all logistic pieces together in order to find the best functional and cost-effective plan. Then, it’s our turn. We usually take little time to come up with a workable concept. When the project is finished and a resident comes up to you to say they just love Wliving in the home you designed for them, that’s our ultimate reward.” The architects of VAN AKEN Concepts, Architecture & Engineering BV in Eindhoven teamed up with Porten Development for two projects with similar names, of which the Houthaven LIFE project in Amsterdam was nominated for the Zuiderkerk architectural design award in 2020.

PORTEN DEVELOPMENT 61 | OUR TEAM We may be a small company, but we think big. Our enthusiastic, smart and compatible team members are not held back by large developer’s ways. Every team member is free to use their entrepreneurial skills and deploy their talents to the max. Meet our team. JOHAN KÖRNER Sweden-born Johan Körner acquired his first property at 22: a fishing cottage in Stockholm. He had two wishes: to run his own business and to go abroad. His work for a daughter company of the Austrian National Bank took him to Vienna, Budapest, Bratislava, and Amsterdam. “I admire the trade mentality of the Dutch, there is always an opening to do business.” In 2013, he and Richard van Wel started Porten Development. “The flexibility of a small team is our strength. The main goal is to connect owners, investors, municipalities and contractors. We’ll bring in the concept and explore our network to find the best match for a specific project. Then it will fly!” CHRIS VAN HOLTHE Before Chris joined Porten Development, he was a project director at MAB, hence he developed a thorough knowledge of the development business. He knows how to look at a project from every angle, getting all parties lined up facing the same direction. Cost calculation is his daily fare. “The freedom we all have at Porten to reach our goals is very inspiring. I love that we are involved in projects that we can be proud of. Thanks to our vast network of specialized architects, building contractors, engineers, and fellow developers we can develop creative inner city projects that will please their users today as well as in the future.” RICHARD VAN WEL At a young age, Richard became fascinated by real estate, and after working as a realtor and a corporate real estate consultant, he finally found his passion in developing areas into neighborhoods where people love to live, work and interact. Elderly people and their living conditions have Richard’s special interest. “Getting every party on the same page to create something valuable gives me so much satisfaction. It is not just putting a building on the map, it is creating a hospitable community that is future proof for people of all ages, because of its set-up. If we succeed in that, we are building a beautiful legacy for future generations.” WOUTER ZUIDAM Wouter and Johan go back more than 15 years and their cooperation is built on mutual understanding and synergy. As a trained builder, Wouter knows the ropes when it comes to technical requirements, the operational process and logistics. Moreover, he loves getting municipalities and investors on board. Even when there are obstacles. “Challenges make our work interesting! The key word is ‘cooperation’. Creating things never goes smoothly, but when you proceed from a general towards a detailed view, it all comes together… I love to see ‘nothing’ develop into ‘something’, a place where people can thrive.” SANDER BREIDER Despite his young age, Sander’s thorough feasibility studies, which incorporate both the developers and the investors’ perspective, are rooted in vast experience in the financial world. His versatility landed him at Porten, where he discovered his other passion: sustainable building. Sander wants to be sure that buildings fit seamlessly into their environment. “A building has to be a place to meet; healthy, and welcoming. It has to contribute to its environment, that’s why I like to create houses and offices that have added value for everyone. Green roofs and terraces, and inner gardens, for example. That’s biodiversity at its best.”
