Description
Holwell Court is a country house built around 1900 by Sir Ernest George in the Queen Anne Revival style. The house is constructed of red brick with a machine tile roof and has an H-shaped plan. It features two storeys and attics, with flush sash windows and a continuous wood cornice with modillions. The entrance elevation includes a central projecting porch bay topped with a Holborn gable and a narrow attic light, flanked by panels. The entrance has a two-panel door with a deep panelled hood supported by iron bars, and is adorned with fruit-carved pilasters and scrolled brackets. Above the entrance, there is a bulls-eye window, and the ground floor windows are topped with triangular brick pediments. The house has hipped three-light dormers and a two-storey wing on the left side that connects to the front wall at a semi-octagonal stair turret with an ogee lead roof. The garden elevation features a six-column Doric loggia between the projections, along with triangular and segmental-headed dormers. There is a plain square tower on the east elevation and a conservatory with two arched lights on the west side.
