From our office in The Hague, we work with a small team of designers and architects - and in close collaboration with our offices in Berlin and Florence - on various complex building projects in the Netherlands and Belgium. We work with conviction and clear visions on a better (living) environment:
Urbanism: we stand for architecture that builds with respect for nature and our (cultural) landscape, in the tradition of European urbanism.
Building: we build with natural materials, in traditional construction and with artisanal precision, without losing sight of the contemporary sense of life.
Sustainability: we have been building, since 1978 and long before sustainability had turned into a marketing strategy, sustainable, careful and future-proof.
Timeless architecture: we create efficient, flexible and timeless architecture that brings together past, present and future in buildings that prove themselves in the long term; buildings that age nicely and have robust flexibility.
