Guillaume Alan designs spaces where architecture, interior design and landscape come together as a single, coherent vision.

Founded in Paris in 1998 and later expanded to London, his studio operates internationally on residential and retail projects.

Each creation begins with a clear intention: to create spaces that convey emotion while expressing a personal sense of balance and harmony. Architecture becomes a tool to shape atmosphere, comfort and well-being — in pursuit of happiness.

Light plays a central role in the creative process — structuring volumes, defining moods and adding a subtle cinematic quality to each space.

Guillaume Alan's work is internationally acclaimed and regularly featured in leading publications, including Architectural Digest.
