Porch House

This property comprises two houses, now a doctor's surgery, located on Corsham High Street. The house to the left was originally built in the late 17th century and the house to the right, known as Porch House, was refaced in the later 18th century with an addition matching the style built in the early 19th century.

The house to the left is constructed of roughcast rubble stone, with a stone-tiled roof edged with slate. It has a coped south gable, a ridge stack, and a stack at the south end, extending over two and a half storeys and two window bays. Dormer gables are present; one is windowless, while the other contains a two-light mullion window with a hoodmould. Leaded lights feature in the gable and first-floor windows. The ground floor has a four-light mullion window with a hoodmould to the left, and a six-panel, half-glazed door with side-lights to the right. All mullion windows have recessed ovolo-moulded detail. Flush quoins are visible at the south-east angle. A parallel rear range extends from the property, featuring a coped south gable, a south end stack, an upper 12-pane sash window, and a former door with a dripstone, now a window, at the south end wall. The rear wall is roughcast, with one window range to the right, and an ashlar-fronted canted bay with a parapet to the left. A rubble stone wall runs from the south-west corner, topped with coping, and ramps up to two ashlar gatepiers with cornices and raised gatestops, finished with scroll capping.

Porch House, on the right-hand side, is roughly symmetrical but appears to be the result of two or three building phases. It is two storeys and attic in height, with a five-window range, and a projecting central porch bay. Twelve-pane sashes are used throughout. The left side, dating from around 1820-30, has an ashlar facade with a raised plinth, band, a south end angle strip, a moulded cornice, and a parapet. It has a Mansard slate roof with coped gables, a north end stack, and one dormer. The central porch bay, dated approximately 1760-70, is part ashlar, with a moulded cornice and parapet, first-floor sashes to the front and sides, all within moulded architraves. There is a moulded, flush doorcase with an iron gate in a Roman Doric columned and pedimented surround on the ground floor. Panelled seats and a six-panel door are housed within a timber architrave inside the porch. The right side of Porch House, seemingly remodelled to match the porch bay, is rendered with a band applied in timber, a moulded ashlar cornice, a parapet, a coped north gable, a north end stack, and one dormer. The windows have unmoulded surrounds, similar to the early 19th-century range. Spearhead iron railings extend across the front of the property. The rear of Porch House features 12-pane sashes and a single 16-pane stair light belonging to the early 19th-century range.
