Description
Nos 19 and 20 South Square are a pair of 18th century style houses designed by Sir Edward Lutyens. They are two storeys with dormers, and feature a recessed central section of four bays. The projecting ends each have three-light windows of a late Georgian design. Each house has a recessed entrance with a corniced porch supported on piers, and the porch cornice extends over garage entrances adjacent to the doors. Four dormers with curved tops are located above the recessed section. The houses are constructed of buff grey bricks with red dressings.
