Colindale Hospital Administrative Block

The Colindale Hospital Administrative Block, dated 1899, is a red brick building with artificial stone details and slate roofs, constructed in a Classical Baroque style. The symmetrical south front features three storeys and a 16-window range. The central three-storey block has three pairs of windows on each floor; ground-floor windows have stone architraves and 9/9 horned sashes; first-floor windows have segmental heads, scrolled keystones, and 6/6 horned sashes; and second-floor windows have arched heads, scrolled keystones, and 5-vaned overlights above 2-light casements with glazing bars. A central doorway is flanked by rusticated columns rising to a segmental pediment with carved foliage. Double-panelled doors are under a 6-vaned fanlight. A modillion cornice tops the building, with a rendered parapet featuring swan-necked centres and a single-bay pediment containing a clock face in a stone surround. A central timber open lantern rises from a hipped roof, with ridge stacks and smaller stacks to the east and west returns.

Recessed two-storey elements flank the south front, featuring canted bay windows and detailing consistent with the centrepiece. The east return exhibits a single sash window similar to those on the south front, and a Diocletian window to its north. A string course is present at first-floor level. The west return resembles the east, with paired sashes to the ground floor. A single-storey hipped extension projects from the north side, with five 6/6 horned sashes in stone surrounds and a narrow 2/2 horned sash to its north.

The north elevation incorporates a ground-floor bay window with 6/6 horned sashes, four sashes to the first floor with segmental stone surrounds and 6/6 horned sashes, and four second-floor casements with arched stone surrounds and fanlights.

Inside, the entrance leads to a glazed screen with double, half-glazed doors and a 4-light overlight featuring geometric stained glass. Porter's offices are located on either side. A Jacobean strapwork style timber chimney piece adorns the east wall, alongside an arched doorway with fluted jambs and half-glazed double doors and a matching door to the west wall of differing dimensions. The main rooms have simple plaster cornices, skirting boards, and boarded timber chimney pieces. Plain corridors connect the rooms, and a simple closed-well staircase is found in the east and west returns.
