House K
Copenhagen — Residential — 2026
A courtyard house in load-bearing brick. Rooms turn away from the street toward one quiet, north-lit court.
Atelier N°7
Architecture for lasting relevance.
An international practice designing buildings, interiors and urban frameworks that are meant to be kept.

( Note — 001 )
Atelier No7 is an architecture practice for a patient century. From Paris, London and Copenhagen we design structures whose proportions still make sense long after their programmes have changed — buildings that are kept, not merely maintained.

Casa Norte.
Lisbon — Residential — 2024
Three courtyards terraced into a Lisbon hillside. White concrete, deep shadows and a single axis running from the street gate to the Atlantic horizon.
( 02 — Approach )
We build less. But make it matter more.
Every project begins with subtraction. We remove until a building becomes inevitable — then we build it properly, from materials that age instead of expire. Six principles govern everything the studio makes.
- 01
Proportion
Rooms are tuned by ratio before they are arranged by plan. Correct proportion is felt before it is understood.
- 02
Light
We design the apertures, not the fixtures. Daylight is the cheapest and most durable material we specify.
- 03
Material Honesty
Concrete as concrete, timber as timber. We do not paint a lie over a structure.
- 04
Context
A building answers its street, its climate and its neighbours before it answers the brief.
- 05
Longevity
We design for the third owner and the hundredth winter. Maintenance is a form of architecture.
- 06
Restraint
One idea per building. Everything else is craft.

The Practice.
Paris — London — Copenhagen
Atelier N°7 was founded in Paris in 2008 by Ingrid Halvorsen and Étienne Marchal. The studio now numbers forty-six architects, researchers and model-makers working across three studios in Paris, London and Copenhagen.
The practice has completed forty-two buildings in eleven countries — houses, museums, workplaces and urban frameworks — alongside a research unit, Works 7:1, dedicated to construction in timber, earth and low-carbon concrete.
The studio remains deliberately selective: fewer commissions, deeper attention. No more than four new projects are accepted each year.
