Carlton Club

The Carlton Club is a gentlemen's club that was rebuilt in 1826-27 by Thomas Hopper, with some alterations made by Chawner and Henry Rhodes around 1840 and again in 1925-26. The building is constructed of Portland stone and has a slate roof, showcasing a very restrained Palladian style. It stands three storeys tall with a basement and is five bays wide. The ground floor features a rusticated podium with a doorway on the left and windows set in semicircular arched recesses, all with glazing bar sashes. The upper floor's glazing bar sashes are framed by a giant Corinthian column order that rises from the podium to the entablature, which has a dentil and modillion cornice and a balustraded parapet. The piano nobile windows are adorned with alternating triangular and segmental pediments. There are cast iron area railings that return up the steps to the entrance.

Inside, the layout is dominated by a grand staircase in a spacious square compartment topped by a coffered dome. The staircase rises in two short flights, unites, then divides at a 90-degree angle, and finally returns in two flights to the first floor, featuring a heavy moulded cast iron handrail. The main rooms include two superimposed dining rooms at the rear, with the upper room boasting heavy marble chimney pieces and ornate stuccowork. Above the entrance lobby is a library with pilasters and large pedimented bookcases. To the northwest and rear, there is a surviving part of an 18th-century building with bows to the west, which has been largely remodeled by Hopper; this section was originally part of White's Chocolate and Gaming House, later known as Arthur's.
