Lavernham House

Lavernham House is a villa dating from approximately 1790 to 1820, with later additions and alterations. It is constructed of stucco over brick, with an ashlar porch and a slate mansard roof. Stucco detailing includes end Doric pilasters topped by a crowning entablature. The house has a double-depth plan with a central hallway.

The exterior features two storeys over a half-basement with attics, and three first-floor windows. It has 6/6 sash windows in plain reveals, with sills; the first-floor centre window is blind. A central entrance has a distyle Doric porch with an entablature and blocking course, leading to a flight of four renewed steps and a four-panel door with a moulded architrave and sidelights. Attic dormers have 6/6 sashes. Ashlar copings are present to the gable end. The basement has three-light windows. The rear of the house retains 6/6 sash windows.

The interior includes a central hall with a dogleg staircase featuring stick balusters and a wreathed handrail.

The house was once the residence of Hannah Forty, the official pumper at the Royal Well, and it forms a group with St George's Terrace (St James's Square).
