Stripped of unnecessary embellishments, the "3PR Cabin – Tre │ på │ rad" designed by R21 Arkitekter reveals its constructive logic: the form responds directly to the chosen structure; nothing is hidden. As a result, this tectonic piece, with its dark tones and gabled roof, emerges from the mist and greenery of the surrounding natural landscape.
Conceived as a modular system of 3x3 units arranged around a central core, the design can be adapted to different needs. Depending on the sun's orientation, views, or the topography of the site, the "3PR Cabin – Tre │ på │ rad" can be rotated or mirrored to suit the specific characteristics of each location.

Project description by R21 Arkitekter
"Tre på rad" is a cabin developed with the ambition of uniting architectural quality, flexibility, and sustainability in a compact format.
The starting point was a simple idea: to create a compact cabin with a focus on spatial, aesthetic, and environmental qualities.
The floor plan is based on a module of 3×3 units. The module can be both mirrored and rotated, therefore the cabin can be adapted to different plots and orientations – depending on sun, view, access and terrain.
The structure defines the form and reveals the constructive logic. The formal coherence and the tectonic character of the piece converge in a total integrity of the project. Nothing is concealed; everything responds to the truth of its construction.
