Walker House Southern Block Including The Cock Tavern Public House

Walker House southern block, which incorporates the Cock Tavern public house, is a block of council flats and a public house built between 1929 and 1930. It was designed by the London County Council Architects' Department under G Topham Forrest as part of the Ossulston Estate. The block is constructed of load-bearing brickwork rendered with coloured roughcast, with the ground floor channelled to resemble stone, and features reinforced concrete balconies. The roof is hipped and tiled, with dormers and tall chimney stacks.

The flats have five storeys, attics, and a basement. They form a long range with a central, round-arched entrance framed by voussoirs and a keystone. Windows are recessed sashes with exposed boxing, topped by a parapet. The public house is three storeys high, with cellars, and has four windows facing Phoenix Road and a six-window return to Chalton Street. The public house frontage has transom and mullion windows with plate glass between pillars, and a main entrance on a chamfered ground floor corner. The interior of the building was not inspected. Walker House forms a group with Chamberlain House, Phoenix Road, and Levita House, Ossulston Street, which includes the Somers Town Coffee House.

The Ossulston Estate is considered the most significant inner-city estate from the inter-war period, demonstrating a considered attempt by the LCC to introduce innovative approaches to inner-city housing estates. It was influenced by Viennese housing models and was innovative in terms of layout and elevation; its development was prompted by the need to balance housing Londoners on outlying estates with the pressures of waiting lists and the urgency of slum clearance.
