Aldwarden Hill and The Gate House and attached screen wall

Aldwarden Hill and The Gate House are two dwellings, built in 1906 by Richard Harding Watt, and originally one house. The construction is of brick with ashlar dressings, incorporating random projecting blockwork, and has a pantiled roof. The architectural style is an inventive Edwardian Free Style, drawing inspiration from an Italianate villa. The building has a rectilinear plan with the principal rooms located at the rear, overlooking the garden.

The exterior is two storeys high. A two-storey, off-centre entrance porch features an arcaded design with a heavy stone architrave. Upper windows are set within architraves, divided horizontally by a projecting transom. The left side of the house has two windows, with pedimented architraves to the ground floor. The right-hand block includes a low attic storey with windows under the eaves and a full-height, round-arched stair window. The front overlooking the garden has a central, shallow, segmental bay with plain window openings. To the left are paired sash windows with margin lights; the right side exhibits irregular fenestration, featuring three round-arched windows, one extending the full height of the building. Blind panelling, pierced by two small windows on either side of the central bay, is located directly below the overhanging eaves. A recessed three-window range exhibits windows within architraves, with cornices to the ground floor; similar windows are present in the basement storey. Many of the windows are unequally divided sashes, featuring a high transom. To the left of the garden front, a screen wall with two segmental arches – one blind – connects to The Coach House. The roof is topped by a belvedere with four arcaded, round-headed windows, balustraded sills, and a hipped roof.

The interior has not been inspected. A screen wall links the main building to The Coach House.
