Rooms made
to be lived
in slowly.

Full-service interior design for private homes, small hotels and one quiet bookshop. We work on two projects a year, stay from the first sketch to the last cushion, and design rooms that age well.

A house turned toward the water.

The villa had been closed off from its own best view - a wall of small windows between the living room and the lake. We took the wall down, set a single oak-framed opening in its place, and let the room do the rest. Everything else followed the light.

We kept the palette deliberately short: European oak underfoot and overhead, hand-troweled lime plaster on the walls, travertine in the wet rooms, and patinated brass for everything you touch. Nothing here is lacquered or sealed against time - it is meant to soften, mark and warm with the family that lives in it.

§ II · The palette

Six materials we return to.

Most of our rooms are built from a short, honest list of materials chosen for how they age rather than how they photograph on the first day. These are the ones we keep coming back to.

§ III · How we work

We take two projects a year so that each one has all of us in the room. No account managers, no handover. The people who draw your home are the people who hang the last picture.

Hauser Atelier
Sofia Hauser & Léon Brandt · Founders
01
The walk-through

We spend a full day in your home before we draw a line - watching the light move, noting where you actually sit.

Weeks 1–4
02
The palette

A physical sample board - every material, in your light, in your hand - before a single supplier is contacted.

Weeks 5–12
03
The drawings

Full joinery and lighting documentation, drawn in our studio and built by makers we have worked with for a decade.

Months 4–10
04
The last cushion

We stay until the rooms are styled, the art is hung and the house is genuinely ready to be lived in.

Months 11–18

§ IV · The studio

A small room above the lake.

Hauser Atelier is a six-person studio on Rämistrasse, a short walk from the water. We were founded in 2011 by Sofia Hauser and Léon Brandt, who met restoring a single apartment and never quite stopped.

We keep the practice deliberately small. It means we can be choosy about the work and generous with the time each project deserves - and it means you will always know exactly whose hands your home is in.
