Station platform buildings at Harrow and Wealdstone Railway Station comprising ticket office range, platform, waiting room blocks, platform canopies and linking pedestrian bridge,

Station platform buildings at Harrow and Wealdstone Railway Station comprise a ticket office range, platform waiting room blocks, platform canopies and a linking pedestrian bridge.

These railway station platform buildings date from 1875 and 1911, with later alterations. They were built for the London and North Western Railway Company.

The south western ticket office range and platform canopies serving platforms 1 and 2/3 date from 1875. The infill platform building on platform 2/3 and those on platforms 4/5 and 6/7 are from 1911, as is the pedestrian bridge which links all the platforms to each other and to the main north-eastern station building (The Bridge).

The south western ticket office range is constructed of cream brick in Flemish bond with stucco, ashlar and yellow brick dressings. The other platform buildings have plinths of red brick in Flemish bond and wooden superstructures. All feature iron and steel-columned canopies with felted and part-glazed roofs.

The north-east elevation (line-side) of the south western ticket office range comprises six, five and nine bays, with the five central bays recessed twice. Openings have segmental arches, with panelled doors (some blocked, some replaced by windows), the two at the centre having side lights and mullioned and transomed overlights. Sash windows, some bricked up and two at the left end with late twentieth-century replacements, light the building. Brick stacks with ashlar cornicing project from the roofline.

The south-west elevation (car park side) displays six, three, three and five bays, with bays ten to twelve projecting to accommodate the main entrance, and end blocks further recessed. The plinth is accompanied by an impost band and rusticated quoins to the entrance block. Segmental yellow brick arches frame most openings, while bays ten to fifteen have round-arched openings, those in bays ten to twelve featuring keystones. An oversailing roof with decorative brackets crowns bays seven to twelve. The left-hand section contains bricked-up openings; bays thirteen to fifteen have recesses flanking the centre, the left one formerly a doorway.

The waiting-room blocks on platforms 2/3, 4/5 and 6/7 comprise thirteen bays with close-spaced six-pane sashes with overlights and part-glazed panelled doors, all with architraved heads. A dentilled eaves cornice runs beneath roofs carried by the platform canopies. Corniced brick stacks project from the roofline. Some openings have been blocked and some late twentieth-century replacement windows inserted. A late twentieth-century eight-bay block on platform 2/3 is of no particular architectural interest.

The platform canopies on platforms 1 and 2/3 feature cylindrical columns with panelled bases and plain capitals, and arch braces with decorative spandrels supporting wooden canopies. The canopy on platform 1 has paired part-glazed cross-gabled roof sections above the main entrances; the canopy on platform 2/3 has similar tripled sections at the centre. The platform canopies on platforms 4/5 and 6/7 have square columns with integral rain-water down-pipes, plain plinths and capitals, carrying cross-braced girders which support part-glazed canopies.

The covered pedestrian bridge features continuous glazing to the upper part of its walls and glazed sides to canopies covering the steel stairs down to the platforms.
