2-56 (even numbers) Colebrook Close, The Lodge and the garages below

Colebrook Close is a private residential development of 28 flats, a caretaker's flat and garages, designed by the architects Marshall and Tweedy in 1934 for property developer Edward Coller. It represents inter-war hacienda style architecture set within a landscaped garden.

The development comprises seven two-storey blocks, each containing four flats, arranged symmetrically around a central drive and turning circle. Behind the blocks runs a perimeter service road with separate entrances from the A3. The garage block is positioned to the north of the site. The blocks are set back from the drive behind hedges and lawns, linked by paths laid in York stone and crazy paving. The drive and service roads are constructed in course aggregate concrete with masonry kerbs, except where the original A3 entrance has been reconfigured for road widening.

The buildings are finished in painted 'Snowcrete' masonry with Langley's green and brown glazed pantile roofs and Crittall metal-framed door and window units, some now with additional secondary glazing. Oak front doors, York stone and tile paving complete the material palette.

Each block comprises seven symmetrical bays beneath hipped roofs with wide eaves and moulded cornices. Projecting hipped-roofed pavilions in the outer bays frame a five-bay ground floor loggia and first floor balcony. End chimney stacks rise through the hipped roof. The blocks are unified by fluted bands as decoration and uniform Crittall windows and oak front doors throughout.

The loggias feature square piers and slightly cambered arches with fluted cills and heads. Behind them, each flat has a glazed door unit with flanking vertical lights of horizontal glazed panes and masonry cills, flanked by smaller adjacent windows. The outer pavilions have tripartite ground floor door units with fluted masonry lintels matching the storey band and parapet on the balconies. First floor pavilions incorporate corner window units and central tripartite windows with fixed central units and smaller side casements. The recessed bays have similar central door units and flanking windows in the same proportions as the ground floor.

Paired entrances at the returns of each block sit beneath flat-roofed porches with fluted parapets and stylised heads to each pier. The entrance doors are varnished oak with glazing bars arranged in a chevron pattern, many retaining original bronze door furniture. The doorcases feature robust stepped architraves. Porch floors, loggias and balconies are tiled in large buff and yellow quarry tiles. Loggia parapet walls and balconies have integral planters. Rear elevations are utilitarian in character.

Flats are generously proportioned with wide axial internal corridors. Upper floor corridors are lit by glazed doors overlooking small balconies adjacent to the staircase, above the porch. On the garden front, each flat comprises an interconnecting sitting room and dining room and a main bedroom opening onto a loggia or balcony. To the rear are a second bedroom, kitchen with rear access, bathroom and originally a separate WC. A small room off the kitchen, in some cases used by domestic staff, completes the arrangement.

Internally, stairwells contain solid masonry stairs with hardwood timber treads and moulded handrails, some now painted. Stairwells, halls and principal rooms feature stepped cornices. Most flats retain interconnecting sliding doors between sitting and dining rooms. Architraves facing the hall are recessed, while those within rooms are moulded. Many flats have flush panel doors and oak flooring.

Living room fireplace surrounds are in marble, some with bold contrasting banding. Bedrooms feature electric radiant panels in mottled, moulded ceramic surrounds, some with flounced sides. Some flats retain built-in cupboards in the hall, main bedroom and second bedroom.

The garage block comprises a row of six garages, one originally a fuel store, with an upper floor flat formerly the porter's lodge within a steep mansard roof, and storage space, originally for boilers, in the basement. The walls are rendered as the main flats, with a similarly pantiled roof.

The garages have tripartite sliding doors with glazed four-pane upper lights. Windows in flat-roofed dormers comprise two wide tripartite windows in the centre flanked by single-light windows. The entrance in the gable end wall, reached by external steel stairs, has a framed door with vertical boards and a cambered head, flanked by a two-light metal-framed casement, with a similar window at ground floor level below.
