PROFILE

Ronald Janssen Architecten has been working since 1999 on high-quality, future-proof architecture with a strong focus on the living environment, the user, and the context. We create designs that respond to societal challenges and spatial complexity—buildings that offer lasting value for users, the surroundings, and our clients.

Our clients—property developers, housing corporations, and municipalities—value our integrity, clear communication, and our ability to link spatial quality with feasibility. We don’t design flashy images, but buildings that prove themselves through use, over time, and in context. Our designs add value to the city, the environment, flora & fauna, and above all, to the people who will live or work in them.

Sustainability – buildings designed for the long term, not 25 but 100 years

Our designs are built around sustainable solutions: robust, low-maintenance, and energy-efficient. Sustainability is not an add-on, but an integral part of our architecture. Think nature-inclusive façades, flexible structures, and future-proof living concepts that truly stand the test of time.

Residential quality – flexibility in use

We design with the user in mind. Light, air, spaciousness, and logical layouts form the foundation. Our buildings are adaptable to changing lifestyles and life stages—ensuring long-term liveability and satisfaction.

Context – a clear relationship with the surroundings

We always seek the right scale, materiality, and form for each location. Whether it's new development in a historic urban fabric or densification in inner-city areas, the context guides our design so that buildings feel natural and grounded in place.

Feasibility – structure, materials, and detail

We create designs that work—not just on paper, but on the construction site. By integrating technical consultants and building partners from the very beginning, we realize projects that are efficient and well-executed without compromising on quality or character.

Flora, fauna and people – environments designed for coexistence

We design for cities where people and nature thrive together—where there is space for interaction, collectivity, and shared ownership. Green courtyards, communal rooftops, nesting habitats, and climate-adaptive features are embedded in our designs. The result: living environments that are not only ecologically rich but also socially cohesive. Architecture becomes a catalyst for quality of life, community building, and urban biodiversity.
