Nine marble species + single-marble signature stair

Editor note

Kith Regent Street specifies nine named marble varieties across its two-floor interior: Estremoz, Rosa Portugalo, Azul Cielo, Volakas, Crystal Tiffany, Pentelikon, Calacatta Vagli, Belvedere, and Calacatta Fantastico Arni. The last — Calacatta Fantastico Arni — also forms the principal stair, a single-marble signature object running from Women's up to the lower level. The material density is the argument: where the listed Nash façade cannot be touched, expression moves to stone. Each room keys to a different marble register, disciplined into a sequence — lightest at threshold (Estremoz, Crystal Tiffany), compressing through walnut and Belvedere at men's, deepening at the lower level. Paired with custom white oak and walnut millwork and brass parquet inlay. The stones span Portuguese (Estremoz, Rosa Portugalo, Azul Cielo), Greek (Volakas, Pentelikon), and Italian (Calacatta Vagli, Belvedere, Calacatta Fantastico Arni) sources. The stair is one continuous piece of stone furniture. Specification is spec-by-named-variety at flagship register; sourcing is through specialist stone merchants rather than off-the-shelf.
