Stef Claes Architect is a design firm distinguished by its timeless approach to craft and its sophisticated use of material. Our approach melds architecture, interior design, and landscape, resulting in singular environments with careful consideration of proportion, atmosphere, and light.

The firm’s portfolio strikes a careful balance. Each project is entirely site specific with designs that are borne from studies of site and environment, while also drawing from a wide array of influences stemming from Stef’s experience living and traveling around the world combined with the backgrounds of his clients. A collaborative studio, our team of experienced design professionals works closely with our clients, ensuring every design is tailored to each client and to their sites. We also partner with trusted builders and consultants to ensure projects are delivered with precision and care.

With a studio in Geneva and a lifelong footprint in Belgium, Stef Claes Architect leads projects across Europe, guiding work through all phases of design and construction.
