Description

Portishead House is a mid-to-late 19th-century residence. It is constructed of coursed squared rubble with freestone dressings and has a slate roof. The north-facing sea front has two storeys plus an attic behind a parapet, displaying four sash windows with architraves and marginal glazing bars, along with pilasters. The ground floor presents three square bays featuring tripartite windows. A terrace extends in front of the building. The east front mirrors the south front in design, with two storeys plus an attic and five windows. A large, two-storey, three-window bow projects from the north end. The south end features an arched entrance leading to a courtyard, topped by a Venetian window. A single-storey Corinthian column porch provides access. Originally the home of the wealthy Bristol wine merchant, John Fisher, a friend and financier of Napoleon III, the house was sub-divided into four flats in the late 1960s.
