St Martins House

St Martin's House is an office building located on St Martin's-le-Grand, constructed in 1925 by architect Leo Sylvester Sullivan, with carved details by Henry Poole. The building features a steel frame faced in Portland stone and has a stone-coped mansard roof. It is designed in a stripped classical style with Graeco-Egyptian details, standing 10 storeys tall with attics and a 7-bay range.

The façade includes a slightly projecting 3-bay portico supported by Greek Doric columns, with palm-leaf carvings on the soffit of the cornice. A giant order of Tuscan piers rises nine storeys to a frieze adorned with Greek key ornament. The windows are revealed and feature decorative metal aprons, with the three central windows on the fourth storey showcasing urn designs. The attic storey has square-headed casement windows, and the boldly projecting cornice is also decorated with palm-leaf carvings.

The rear elevation, facing 33 Foster Lane, maintains a similar style with a plain tradesmen's entry and Tuscan piers on the three middle floors. Inside, the entrance lobby boasts carved rosettes on the coffered ceiling, Tuscan pilasters, and classical door architraves with carved acroteria, along with mahogany doors. The hall features two marble Greek Doric columns, and both the hall and upper landings have coffered decorative plaster ceilings, panelled walls, and neo-classical doorcases. An open-well staircase is highlighted by a ramped mahogany handrail set on carved and turned balusters.
