Description
Ventnor House, located at 11 London Street, is a house dating from the late 17th century or early 18th century, which was extended around 1780 and had its front altered.
The building is constructed from flint and red brick, with a roof covered in pantiles.
The main facade faces west onto London Street and features four bays, two storeys, and an attic. The pitched roof is pantiled, and the bellcast eaves are supported by a canted dentil cornice. The windows are all six-over-six unhorned sashes with concealed boxes; those on the ground floor have skewback gauged brick arches, while the first-floor windows have simple lintels. The brickwork is laid in Flemish bond. Slightly off-centre on the ground floor is a wooden doorcase with console brackets, a six-panelled door, and a slim over-light.
The south elevation, which faces The Pightle (formerly known as ‘Cobb’s Pightle’), is one-and-a-half bays wide and primarily made of flint rubble. Brick tumbling and quoins indicate the original size of the house and show how it has been extended both upwards and outwards. A former window and doorway have been blocked. There are tie-plates at the upper levels and a single window opening in the attic. The gable apex features a chimney stack that was rebuilt in the 20th century.
The rear elevation, facing east towards a yard, has been rendered. A late 20th-century fire escape connects an extruded attic dormer and a first-floor doorway to the yard. The window arrangement is irregular, including two casements, one small sash, and a small canted bay.
