Description
St Dorothy’s Convent is a detached house, originally dating back to around 1740, with significant alterations made in the late 19th century and again in the late 20th century. The house is constructed of brown brick with red brick dressings, featuring a moulded brick plinth and pilasters that support a cornice at second-floor level.
The building has three storeys and a basement. The front facade has a single window, while the return to the garden displays three windows. A 20th-century entrance is set beneath a canopy. The windows are flush framed sashes with exposed boxing, and gauged red brick segmental arches. A first-floor sash above the entrance is round-arched and has a cast-iron guard. The garden front includes a central full-height canted bay. Ground-floor and first-floor windows have been altered to French windows, with early 19th-century cast-iron balconies on the first floor. The building is topped with a parapet and a 20th-century plain cast-iron balustrade.
The interior of the building was not inspected during the listing process. Historically, following the Crimean War, the house served as the Sailors' Orphan Girls' Home before becoming the residence of General de Gaulle and his family in 1940-2. It was subsequently converted into a finishing school in 1968.
