Residence, Île-de-France [FR]

EeStairs + Agence Romeo Architecture + Studio Piet Boon

In this private residence in Île-de-France, Agence Romeo Architecture, working with Piet Boon, has shaped a grand apartment interior with gallery-like restraint: calm panelling, pale timber floors and carefully controlled light. The staircase occupies a compact corner between levels, quietly functional yet central to how the home is experienced.

EeStairs realised a walnut spiral stair defined by deep, continuous guardrails to both sides, a closed underside, and a handrail formed as one uninterrupted sweep. The principal challenge was achieving visual continuity through tight curvature. A concealed steel structure provides stiffness, while precision-formed templates fixed the geometry so the walnut surfaces could read as seamless. Workshop trial-assembly, careful segmentation for site handling, and concealed joints ensured the stair reassembled with clean alignments and no disruptive breaks in the lines.

American walnut was chosen for its warmth and depth of grain, with walnut veneer used where curvature demands stability and flawless surface consistency. Finished in natural oil, the timber remains tactile and quietly luminous, giving the staircase the presence of something shaped rather than assembled.
