Søndergård Concrete House — primary facade seen from below

A single board-marked concrete volume set into the dune line — closed to the wind, opened entirely to the sea.

A single board-marked concrete volume set into the dune line — closed to the wind, opened entirely to the sea.

The house is organised around a single load-bearing wall that runs the length of the plan, dividing served from serving space. Daylight enters through deep reveals cut into the mass, moving across the rooms as the day turns.

Materials are held to three: cast concrete, oiled oak, and blackened steel. Nothing is added that does not carry load or carry light.

Philosophy & people

Architecture is the discipline of removing — until only what holds weight and light remains.

Founded in 2009 by Ingrid Halden, the studio works between Copenhagen and Oslo on houses, cultural buildings, and adaptive reuse. We build slowly and in few materials, believing that restraint — not gesture — is what lets a building belong to its place. Every project begins with the section: how mass meets ground, and how light is let in.
