Description

Number 29 and Semington House are a detached house, now divided into two dwellings, built in 1794. The construction is of limestone ashlar with a Welsh slate hipped roof and stone stacks featuring moulded cappings. The main block is square, with extensions to the rear for service use. The building is three storeys high and has a three-window front.

The central doorway to Semington House features six fielded panels and a fanlight, sheltered by a portico with paired Ionic columns and angle volutes, a modillioned cornice. Flanking the doorway are tripartite 12-pane sash windows; the ground floor is rusticated and the pilasters extend up to the eaves. A double plat band runs along the first floor. The central first-floor window is a sash, accompanied by tripartite sashes on either side. The second floor has three 9-pane sashes, one of which has been replaced with a 20th-century double-glazed window; the windows are finished with a modillioned cornice to a plain blocking course.

The garden front, on the right return, has a central double door with six panels, a flat stone hood on brackets, and sashes to the sides and on each floor, mirroring the front elevation. The left return is similar to the front but features two three-light mullioned windows to the cellar and a blind window where a central door would have been.

A two-storey service wing extends to the rear. The left return has a double stained-glass door with margin-pane glazing bars, leading to Number 29. There are also two-light mullioned casements and 9-pane sashes. A shorter service wing on the left side has a sash window and a planked door.

Inside Semington House, the staircase has stick balusters and a wreathed handrail. Number 29 has separate service stairs and six-panelled doors set in moulded architraves. A classical marble fireplace is in Number 29, while the rear services in Semington House retain chamfered spine beams with run-out stops, planked doors, and a corner cupboard with a dentil cornice. The building was originally constructed for the Bruges family.
