74, St James Street SW1

No. 74 St James Street is a former gentlemen's club built between 1843 and 1845 by architects George Basevi and Sidney Smirke for the Conservative Club. The building is constructed of Portland stone with a slate roof and features a Palladian style with more relaxed detailing typical of the 1840s.

It stands three storeys high with a basement and is seven bays wide. The ground floor has a rusticated podium, with the end bays featuring a Tuscan porch on the right and a corresponding canted bay on the left, with recessed glazing bar sash windows in between. The upper floors are articulated by a giant order of Corinthian columns in the central five bays, while the end bays are treated as pilastered pavilions. These frame Venetian windows with Corinthian column dividers and pedimented windows in the central five bays, also with glazing bar sashes. A stone balustrade runs along the first floor above the porches, and the giant order supports an entablature with a deep enriched frieze below a dentil cornice and a balustraded parapet. The building is enclosed by cast-iron area railings, and the stepped return features tripartite windows and a canted bay. The rear part of the premises was rebuilt in the mid-20th century.

Inside, the building retains a central square room with a circular upper gallery topped by a dome, with walls decorated in the style of Raphael's Logge by Sang and Naundorff. The original staircase was replaced by a smaller one in the 1960s. The Tie Smoking Room on the first floor front has a heavily carved ceiling. The Dining Room and Library to the north are long rooms divided into three sections by columns and pillars.
