Portland stone, Grade II-preserved (1905 façade)

Editor note

The 1905 Portland stone façade of 45 Old Bond Street, previously De Beers London. Grade II-listed, preserved essentially intact under Historic England consent. Queen Anne-style composition — rhythmic window bays, roofline, fenestration all protected. Any alteration requires consent. For Ferrari Style London, the envelope is a starting condition, not a design variable. The storefront glazing is edged in dark steel with brassy gunmetal tones to contrast the light Portland stone — a restrained modification at street level that leaves the building's heritage legible. This Directory entry captures the material argument by way of constraint: when the street-facing material is frozen, the architectural expression moves inside. Kith Regent Street makes the same move against a Nash-era stone façade — the UK heritage-forced-interior-expression pattern. Portland stone itself (Isle of Portland, Dorset limestone) is specifiable as new-build material; this entry is specifically about heritage preservation as architectural argument, not contemporary sourcing.
