Bourne Estate (Northern Part) Denys House Frewell House Ledham House Radcliffe House Redman House Scrope House Skipwith House

The Bourne Estate (Northern Part), encompassing Skipwith House (1-55), Ledam House (1-34), Redman House (1-17), Radcliffe House (1-105), Scrope House (1-34), Frewell House (1-55), and Denys House (1-30) on Clerkenwell Road, along with properties at 91-93 and 99-101 (Odd) Leather Lane, and 87-101 (Odd) Leather Lane, is a housing estate developed for the London County Council between 1901 and 1903. The estate was designed by the LCC Architect's Department, under the direction of W E Riley with E H Parkes serving as chief assistant.

The buildings are constructed primarily of red, orange, and stock bricks, accented with blue and glazed bricks. Portions of the upper elevations, particularly those facing Clerkenwell Road and Portpool Road, are stuccoed. The roofs are slated, and the chimneys are brick. Stone string courses, parapets, and segmental arches are also present. Concrete open stairs and balconies feature iron railings, and the windows are wooden sash and casement types, with some set within segmental brick arches and incorporating brick aprons.

The architecture is in a free Classical style, incorporating Arts and Crafts details, developing the style established by the LCC’s earlier Boundary Street and Millbank estates in a more formal direction. The estate comprises five-story flats, with some sections featuring a sixth story in the roof. The layout is enclosed, with five blocks arranged parallel on a north-south axis – Shene, Ledham, Skipwith, Denys, Frewell and Scrope Houses, separated by narrow quadrangles that were once formally planted. Long east-west blocks, Radcliffe House and Redman House, define the perimeter, punctuated by broad arches providing access to the estate’s center. These perimeter blocks have stuccoed upper stories with giant pilasters.

Radcliffe House features a long elevation fronting Clerkenwell Road, shorter elevations in two sections facing Leather Lane, and a canted corner with a principal entrance arch to the estate. Pyramidally capped towers flank this corner entrance. Ground-floor shopfronts are present along the roads, defined by granite piers. The upper stories fronting Clerkenwell Road alternate between plain brick elevations with dormers in the roof and slightly recessed stuccoed sections featuring giant pilasters rising through three stories and a parapet. Three broad, moulded segmental arches lead into the estate's central area, with the corner arch more elaborately detailed with voussoirs and small brick windows above.

The Bourne Estate holds historical significance as a model for public housing erected in Vienna after the First World War, and subsequently influenced housing developments in London such as the Ossulton Estate and private mansion blocks of the 1930s. Later alterations have been made to the estate.
