We believe that we can make a better living environment together. We share knowledge with experts in the field of sustainability, and with our integral approach sustainability is an important design ambition in all our buildings right from the first sketches. We work on the basis of a broad definition of sustainability, built upon three pillars: WORLD | WE | VALUE.  Our mission is to incorporate and unite these themes in all our projects, from the first sketches to completion. This is the way we want to make buildings that positively influence the quality of life.


We want to have a positive impact on nature and the environment with our buildings. We can achieve this by carefully selecting sustainable materials and reducing the consumption of energy, water and natural resources. In addition, we aim for flexible and circular buildings that can adapt to changing needs or can be partly reused. Nature-inclusive building is an important aspect that we try to integrate into all our designs.


We design with the conviction that a well-designed environment has a positive influence on the health and well-being of its occupants. In this way we create spaces that stimulate social interaction through healthy and comfortable interior climates. We make buildings for active users with spaces that encourage people to exercise and take the stairs instead of the elevator. Creating environments where people can connect, feel at home and live together happily.


Our ambition is to create added value for the local context, not only physically but also in a civic and economic sense. That is why we devote so much attention to a building’s environment: attention for the spatial quality, the programming and the solidity of our designs, as well as the life cycle costs that they entail. Our goal is to create spaces and buildings in consultation with and embraced by their users, ensuring they are of lasting value for their surroundings.


By considering climate and orientation in the design of the volume and skin right from the start of the process, we can reduce the building’s operational energy consumption. For the remaining energy needs, we work with energy and installation consultants to integrate sustainable installation concepts into our designs. We see the careful incorporation of elements to generate renewable energy in the built environment as an important aspect of integral design.


The repurpose of existing structures and design of circular buildings will significantly reduce demand for raw materials now and in the future. By making elements demountable and tracked in a material passport, we can turn future buildings into material depots for high-level reuse. The materials used are carefully selected on the basis of their environmental impact, favouring renewable and bio-based materials minimising embodied carbon. In addition, we aim to extend the life-span of buildings by designing adaptable spaces that can respond to changing functions and requirements.


In collaboration with landscape architects, we integrate nature inside, around and on top of our buildings. This has a positive effect on both the health and welfare of people, micro-climates and biodiversity. Green indoor and outdoor spaces offer possibilities for recreation, local food production and water storage when it rains. Collecting and storing rainwater improves climate-change resilience, while the water can also be reused for various purposes inside the building.

The roof tiles of the former PTT building have been replaced with solar slates in a neutral, dark color. As a result, these PV panels are practically invisible, and the high-quality aesthetic appearance of the roof has been preserved

The roof tiles on the market side have been replaced with solar slates in a neutral, dark colour. As a result, these PV panels are practically invisible, and the high-quality aesthetic appearance of the roof has been preserved. The energy concept has been customized for this building. Residual heat from the data equipment of the KPN servers in the basement is used to preheat the tap water and to heat the floors in the apartments and restaurant. Water is also heated with solar boilers on the flat roof at the rear of the building. The building is heated and cooled with electric heat pumps. Enough energy is generated to supply the needs of almost all apartments and some of the restaurant.

Our buildings are designed with an eye for the well-being of users. On the basis of the desired programme, we make spaces that not only offer comfort and safety, but also maximize focus and productivity. We make exciting spaces and architectural routes through the buildings that we design, spaces that surprise and intrigue. The well-being of people can be positively stimulated with the natural light, the right materials – often natural – and colour schemes. Moreover, inclusion and accessibility of buildings is important in allowing everybody to experience the architecture.


To stimulate the health of users, we encourage physical activity by integrating facilities for cyclists and pedestrians, and by designing spaces in such a way that people are encouraged to take the stairs. In addition, we promote a culture of healthy and communal eating. Ultimately leading to places that enhance the overall well-being and happiness of people.


We want to design spaces that foster social interaction between the various users of the building and their neighbours through, for example, shared areas. We try to design these spaces in such a way that they invite activity and involvement by users. Shared spaces for social interaction not only improve the health and welfare of the users but also enhance the sense of ownership and responsibility, ensuring the continuation of engaging and liveable communities.

Zonnehof combines two schools under one roof, each with its own identity in light, color and organization

The design brings together two different schools under one roof, without compromising their individual identities. Each school has a separate entrance with its own playgrounds. Within the more generic structure of the building, the internal organisation of each school has been custom designed. As a result, two entirely different spatial settings co-exist inside the building. The public elementary school De Grote Beer is organised into a number of educational clusters around separate learning plazas, while the A. Bekemaschool has compact classrooms or ‘base camps’ around large central learning plazas. Atriums in both schools connect different levels and help people find their way.  Various types of skylights admit daylight into the heart of the schools. This, in combination with the restrained material and colour choices, contribute to a bright, clear learning environment.

The holiday home truly enhances the well-being and health with a complete wooden finishing, optimal daylighting through large windows, a big terrace and lots of greenery around the building
Kaap Noir embraces the soul and spirit of Katendrecht, with its edgy naval history. The bold and industrial looking mixed use building, with flexible loft like floorplans and exoskeleton of steel, shelters a warm and playful heart for public and communal services


We carefully investigate what a building needs to be: a new icon for the area, or a careful extension to the existing urban fabric and part of a larger system. Our aim is to preserve and strengthen local values as much as possible by meticulously integrating a building into its surroundings. Designing on the basis of the ‘genius loci’ allows existing structures to be strengthened, and thus the building can be of social and economic value to a larger area.


By deploying high-quality materials and by detailing in a well thought-out and careful manner, we contribute to the solidity, sustainability and flexibility of buildings. Reducing their life cycle costs and simultaneously making them future-proof to retain their value. By setting up a more efficient design and construction process, we try to optimise the use of available economic and spatial resources. On a larger scale, we promote the implementation of robust circular economic models which favour sustainable and local investments.


We believe that by designing attractive public space, we can create places that are appreciated and embraced by users and people from its surroundings. Designing in dialogue with users and neighbours, integrating local culture and ensuring equitable and diverse living environments makes people feel part of the building and the community. This results in places where people want to be and encounter one another, and places that people feel responsible for.

The car-free passages in between the blocks and the encroachment zones in front of the houses have been designed as meeting places for residents and as a play area for children from the neighbourhood

The 19th-century district of Bospolder-Tussendijken has been undergoing restructuring for decades. The more recent plans aim to bring more high-income groups into a district with a culturally highly diverse population.

Several socially sustainable aspects are incorporated in The Hudsons, on various scales. At block level, all homes are organized around 5 collective courtyards, with private and communal gardens. These roof gardens form a familiar environment for residents, where small children can play safely and neighbors get to know each other better. The car-free passages in between the blocks and the encroachment zones in front of the houses have been designed as meeting places for residents of adjacent building blocks and as a play area for children from the neighbourhood.

The new entrance of the Maassluis museum functions as a beacon in the surrounding roof landscape, integrated into the historic street scene through the use of contemporary shapes and high-quality materials and detailing
Jonas is a new concept for collective and sustainable living, containing a mix of different types of rental and owner-occupied apartments, wrapped around beautiful designed public spaces

How generous can you be! The doors are open, and the living room and forest are accessible to the public. During the daytime, everybody can visit the canyon or stroll around the harbour through the building. During the summer, the building and surrounding spaces become a venue for all sorts of activities: swimming in the sheltered natural swimming pool, watching a film from the rock (projected onto the front facade of the building), playing beach volleyball on the square, or sunbathing on the rooftop beach. During the winter, the building is like a warm and welcoming fireplace glowing in a living room. The result is a sound and coherently programmed building that breathes life into this strip of land. A building people can visit and where people can come together. A real heart for IJburg!
