1-4 Causeway House

Causeway House is a detached house that has been divided into four flats. It was built in the early 19th century, with a 20th-century addition facing the road. The exterior features solid rendered walls and a hipped slate roof. The chimneys are rendered, with the one on the south side wall having paired octagonal shafts with panelled sides. The house has a double-depth plan, with low closet wings at each end of the road frontage.

It is two storeys tall, with single-storey closets. The garden front has a five-window range, where the end windows are set in slightly projecting pavilions with hipped roofs. The centre of the ground storey features an Ionic order of four columns with Doric end piers supporting an entablature, resembling a porch but set directly against the wall. There is a central doorway that is now blocked, with French windows on either side. The centre upper-storey window is blind, while the sash windows on either side have four over nine panes plus margin panes. The pavilion windows have six-paned sashes, except for the upper second-storey sashes which have only three panes. The ground-storey windows show the outline of former straight hood moulds.

The eaves cornices are deep and project more over the pavilions, supported by shaped brackets. The left (south) side wall has a round-arched doorway with a chamfered surround and keystone, featuring a four-panelled door with the top two panels now glazed and a patterned fanlight. The right side wall, visible from Meadowville Road, has an upper-storey canted bay window with barred sashes and a top cornice, with six over six panes in the centre and four over four panes on either side.

The rear elevation facing Northam Road has gabled closet wings, each with a round-arched window featuring six-paned sashes. On either side, there are paired Doric pilasters supporting a plain projection that likely once held an entablature. The gables have plain bargeboards, and the centre of the rear elevation is occupied by a large late 20th-century addition. The interior has not been inspected.
