Ashtead House

Ashtead House, now divided into three dwellings, largely dates to the 18th century with a core of 17th or earlier origins, and later 19th-century additions and alterations. The house is constructed of handmade red brick, some with burnt headers, predominantly in a Flemish bond, and has a slate roof. The building's form is approximately rectangular and double-depth, resulting from 18th-century additions to the east and south of a preceding single-depth structure, with later additions at each end.

The main three-storey, five-by-five bay west front features a slightly offset three-bay bow constructed in a header bond. Decorative features on the bow include a three-course band over the first floor and a similar band and parapet over the second floor, all carried around the bow. Its windows are segmental-headed sashes with 12, 12, and 4 panes respectively. A narrow bay to the left contains an internal porch (the entrance to No.2), featuring a doorway with moulded brick pilasters and entablature. Above the doorway is a 12-pane sash with an exposed box in a segmental-headed recess, and a segmental-headed nine-pane sash on the second floor. A wider bay to the right has a glazed lean-to addition at ground floor, a modern three-light window on the first floor and a segmental-headed nine-pane sash on the second floor. The roof is hipped on a square plan, with a single chimney on the ridge.

To the left (north) is a set-back facade of the earlier building, spanning two and a half storeys and three narrow bays, with a modern flat-roofed wing covering the first bay. A glazed lean-to addition sits at ground floor, two windows are present on the first floor, and a continuation of the first-floor band runs above them.

The south front (for No.1) has two extruded chimney stacks defining three bays across the centre and left side; a large, flat-roofed three-bay addition (said to have been a ballroom) covers the centre and left ground floor, with French windows in the first bay and 15-pane sashes in the others. Otherwise, the windows are mostly 12-pane sashes with exposed boxes. The east side (the entrance front to No.1) has a doorway inserted in the third bay, with 12-pane sashes to the left and above, and narrower eight-pane sashes in the fourth bay. A two-story former service wing (No.3) continues to the north and is not of particular architectural interest.

Internally, No.2 retains remnants of a former timber-framed range on a north-south axis, including chamfered axial beams at ground and first floors, a king-post roof truss on the top floor with a tie-beam terminating approximately 2 metres inside the present front wall, and the upper two flights of a 17th-century staircase with a closed string and turned balusters. No.1 contains a fine 18th-century open-well staircase, featuring carved brackets and two fluted balusters per tread.
