The Quadrant

The Quadrant is a group of offices and shops located on Regent Street in the City of Westminster. It is part of the southwestern half of Sir Reginald Blomfield's extensive redesign of Nash's Quadrant, which was initiated around 1910 and completed between 1920 and 1923. The design draws inspiration from Norman Shaw's neo-Baroque elevation of the Piccadilly Hotel.

The building features a stone facade and slate roofs, with a podium that includes a ground floor and mezzanine, three upper stories, and a steep mansard roof with dormers. The podium is characterized by bold pulvinated rustication on its piers, while the upper floors are made of ashlar and have windows with flat surrounds. A rich modillion eaves cornice runs along the top, and there is a continuous range of dormers in the roof, which is topped with bronze ridge cresting. The building also has prominent banded and corniced chimney stacks.

A rusticated semicircular arched bridge, which masks the entrance to Swallow Street, features an open, three-story Doric columned loggia reminiscent of Somerset House. The composition of The Quadrant is completed by a slightly advanced pavilion with a concave pyramidal cupola roof, which balances similar features found at the eastern end of the Quadrant.
