17 Carlisle Street is a Grade II listed Georgian townhouse, dating to circa 1756, built as part of Soho’s 18th-century residential expansion and expressed in its red-tinted stock brick facade, four storeys over a basement, and the characteristic formal doorway with fanlight and pediment. Over the centuries it evolved in line with Soho’s wider shift from domestic house to mixed-use commercial use, but it still retains notable historic fabric internally - including enriched plaster cornices, period chimneypieces (including Adam-style and Rococo elements), and a dog-leg staircase with slender balusters and doric newels. It was formally listed in 1958, recognising its architectural quality and its place with the coherent Georgian townscape around Soho Square.
