The helicoidal staircase
The white
ribbon
Four storeys of half-light, and at their centre a ribbon that climbs. The helicoidal staircase is carved in white statuario marble: monolithic treads spiralling into the void with no central column, held by the quiet wisdom of geometry alone. From the skylight above, a single beam descends the spiral and kindles the marble’s vein, while the burnished brass handrail — the only gold permitted — runs like a thread of amber through the dark. In our Aprilia workshop each tread is shaped on a template, dry-assembled and numbered before the journey: so the spiral reaches Mayfair already perfect, like a single stroke of the chisel.
