Plinth
Waterproof reinforced concrete, a white tank. Holds the slope, takes up the lower living level.
Project · SOCKEL
Hanghaus Dortmund.
We build from the structure. The plinth as the language of the building — waterproof reinforced concrete that holds the slope and carries the living spaces. Concept, variant study, design and construction management from one hand.

Think out of the slope, not against it.
The slope in Dortmund-Lütgendortmund falls roughly 18 % to the south. Rather than levelling the volume out, we thought of the plinth as structure — a solid retaining wall of formwork concrete that holds the soil and at the same time takes up the lower living level.
Above it the main volume sits more lightly, with a set-back façade and a cantilevered roof. A gesture that draws the building away from the slope and at the same time acknowledges it.
The triple-zero reading carried through consistently: Zero Energy through a brine-to-water heat pump plus 18 kWp of PV plus a 12 kWh battery. Zero Emissions through a material choice fit for the circular economy. Zero Waste through formwork concrete with timber shuttering and exposed CLT that can later be dismantled.
Three layers. Three readings.
Living
CLT solid timber. Left exposed where it could be. Structurally decoupled on the plinth.
Roof
The PV layer. Closes off the volume and supplies own consumption plus the heat pump.
Subpage status
This page is a stub from the night of 21 May 2026. The full cinematic-3D subpage (exploded view · 3D section through the plinth · six-phase building process · KPI block with 3D diagrams) will follow in sprints 5–7. The 3D model is built in Blender as a generic, conceptual model — not as a reverse-engineering of the real drawings (special-protection requirement).
