Architecture
for those
who notice.

Casa Olivar · Mallorca · 2024 Plate 01

We are Atelier Roux — an architecture and interior studio working between Antwerp and Oslo. We build for the long hours: the quiet morning at the window, the long table at dusk, the room you keep coming back to without quite knowing why.

— Manifesto, no. 002

A building is a kind of argument about how to live. We try to argue softly, and at length. We choose materials that improve as they age, rooms that resist their first interpretation, and details that reward a second look — five years later, ten years later, in a different light. — Léa Roux, on the studio's tenth year

No. 03 / Cultural Commission

Horizon Pavilion, on the estuary.

A long, low art pavilion cantilevered ten metres over the tidal mouth of the Westerschelde. Fritted glass casts striped shadow on the water at low tide; at high tide the building becomes a horizon line of warm light. The brief was for an art space; we delivered a clock.

§ 04 · Method

A slow process, on purpose.

Every commission begins with a long walk on the site, and ends with a printed monograph. In between, five stages — each given the time it needs, never less.

  1. / 01 Listening
    We spend a season on every site before drawing a line. Weather, light, sound, neighbours, smell. Three long client conversations, transcribed and bound. A brief is written collaboratively at the end.
    Stage 012 — 4 months
  2. / 02 Sketching
    Pencil on tracing paper. Three to five distinct schemes, each pushed to the point where its limits show. We present every option, not just the winner — clients should see the road not taken.
    Stage 026 — 10 weeks
  3. / 03 Modelling
    Physical models, always. At three scales: 1:200 to find the building's stance, 1:50 to find the room, 1:5 to find the joint. We resolve detail in cardboard, basswood, and clay before any digital tool is opened.
    Stage 033 — 5 months
  4. / 04 Drawing
    Construction documentation, full set, in-house. Bespoke specifications for every material, sourced from a network of fabricators we have known for fifteen years.
    Stage 044 — 8 months
  5. / 05 Building
    On site weekly. We do not hand off — we run the build with the contractor, side by side, until handover. Five-year aftercare is included on every project.
    Stage 0512 — 30 months
§ 05 · Palette

Materials that age well.

We work from a small, deliberate library of materials chosen for how they wear, weather, and reward the touch of a hand. We refuse anything that depends on being new to look good.

  • Board-formed concrete Belgian dimension stone
  • Pietra Serena Tuscany, IT
  • Charred Japanese oak Yakisugi, Hokkaido
  • Unglazed terracotta Impruneta, IT
  • Lime render Slaked, hand-applied
  • Solid brass, raw Patinated by use
  • Belgian linen Libeco, undyed

§ 06 · The Studio

A small office, with long memory.

Atelier Roux was founded in 2007 by Léa Roux after fourteen years working between Peter Zumthor in Haldenstein and Vincent Van Duysen in Antwerp. The studio has stayed deliberately small: fourteen architects, two model-makers, one librarian. We refuse more than four commissions in any year.

We design buildings, interiors, exhibitions, and furniture — but our deepest interest is in the long, ordinary life of a finished room. We return to every project annually for the first five years, with a camera and a notebook. The work continues after the keys are handed over.

We teach. We publish. We rest in August.

Essay 14 min read · 04.2026

On the patience of a north window — light as the slowest material we work with.

Concrete sets in days, glass is cut in hours, and a window full of north light takes the entire life of a building to finish. Some thoughts after twelve years on the same wall.

Léa RouxNo. 47
Field Note 6 min read · 03.2026

A week with the terracotta furnace at Impruneta — what you learn by watching things fail.

We sent four of the studio to Tuscany to spend a week at the kilns. They came back with two crates of broken samples and a different idea of what "finish" means.

Niels BauwensNo. 46
Lecture 22 min · 01.2026

Notes from a lecture at the Bartlett — on resisting the brief.

Léa's keynote on why every good building has at least one moment where the architect quietly refused to do what was asked, and what that moment costs and earns.
