Byrom House and Eastward Extension

Byrom House and its eastward extension, located on the north side of Clapham Common, date from around 1792. The building is symmetrical, featuring five windows across three storeys and a basement, constructed of stucco. A flight of steps with quadrant abutments leads up to a porch supported by acanthus columns. The ground floor windows have a cillband and pediments on consoles, while the first floor windows also have a cillband and cornices on consoles, with the central window featuring a pediment. The building is topped with a dentil cornice and a blocking course, and has end stacks adorned with anthemion neckings and cornices. A richly decorated boundary railing sits on a low plinth. The circa 1900 extension to the east is also five windows wide, built of yellow stocks with red brick bands and dressings, stone lintels, and a stone entablature over the second floor. It features a red brick and stone round-arched entrance framed by a corbelled hood, with a two-storey canted wooden bow window above.
