1 and 2 St James's Street, including 64 Pall Mall

This building, known as 1 and 2 St James's Street, including 64 Pall Mall, is a corner block of offices designed in 1882 by R. Norman Shaw for the Alliance Insurance Company. It features red brick construction with extensive stone dressings, showcasing rich color variations and decorative molded brick panels. The architectural style is "Queen Anne," influenced by Flemish Renaissance and French designs.

The structure consists of four tall storeys, a basement, two storeyed attics in gables, and a five-storey corner turret. It has six windows facing St. James's Street, with the three on the left set in a slightly advanced gabled break. The ground floor is banded in stone and includes two large semicircular shop windows flanking an enriched doorway with an entablature. The window arches are deep and molded, with alternating stone and cut brick voussoirs.

The upper floors feature mullion-transom windows, with the first floor having tall windows with two transoms and enriched heads and capitals carved on the dividing piers. There are figured brick and stone friezes and panels, along with sill bands and cornices. The gable is shaped with scrolled kneelers and capped with a pediment. The corner turret, which is corbelled out from the ground floor, has mannerist pediments above the windows and a finialed roof.

The return to Pall Mall includes two similar large shop windows and matching fenestration and details across five bays above, also topped with a gable. First-floor cast iron balconies rest on stone corbelling on both fronts, and there are lofty stone-dressed stacks. This building is noted for its influential commercial design.
