Description
26 and 26A Ferncroft Avenue comprise a detached house and an attached former coach/motor house, now converted into a dwelling. The house was built in 1898, with the coach/motor house likely added later. The design is by CHB Quennell and was constructed by GW Hart.
No. 26 is built of red brick with a tile-hung first floor. It has tiled, hipped and gabled roofs with overhanging bracketed eaves, tall brick chimney stacks, and a dormer with a small gable. The design is asymmetrical, with three storeys and a single-storey, two-window bay to the right. A left-hand gabled bay features canted bowed bay sash windows to the ground floor, with an entablature lintel that extends across the facade on columns and to the first floor, featuring a pulvinated lintel and cornice, and a tile-hung apron. The third floor has a Venetian-style sash window in the gable, with short lengths of moulded cornice at the angles, mimicking a broken pediment. The central entrance bay has a porch formed by an entablature and columns with enriched capitals, topped by a cast-iron and glass hood. A part-glazed, panelled door has an overlight. To the right is a tripartite sash, with a corresponding sash on the first floor and a single sash above the porch. The single-storey bay contains two sashes with gauged brick flat arches, a brick modillion cornice, and a blocking course.
No. 26A is constructed of red brick and has tiled, hipped and gabled roofs with overhanging eaves and an eaves cornice extending across the gabled left-hand bay to form a pediment. It's also asymmetrical and has two storeys. The fenestration is irregular, with two windows. A former vehicle entrance in the gabled bay has been converted into a window and entrance, featuring a central casement above, with a relieving arch in the pediment and an arrow slit window above. A right-hand bay has a segmental-arched window, partly obscured by a 20th-century window, with a staircase leading to a first-floor entrance and porch formed by an entablature carried on a column. A three-light window is positioned on the first floor.
