Rayner's Lane London Regional Transport Underground Station Including Shops and Platforms (Including Rayner's Lane Station, Alexandra Avenue)

Rayner's Lane London Regional Transport Underground Station, including shops and platforms, was built in 1938 by Charles Holden and Reginald Uren. This London Underground station features a combination of reinforced concrete post and lintel construction, with red brick infill in some load-bearing areas. The flat concrete roof slabs create a broad cornice band under deep eaves, and the symmetrical design is evident on the bridge over the tracks.

The single-storey frontage facing Alexandra Avenue includes corner kiosks with original curved shopfronts. Side entrances lead into a square double-height ticket hall, which connects to a single-storey rear bridge. From there, stairs descend under stepped enclosures to the platforms. The platform structures are integrated with the hall, bridge, and stairs, set back from the tracks beneath a deep concrete canopy. This area is divided by clerestory windows, with a waiting area located between metal screens at the foot of the stairs. Enclosed waiting rooms feature curved ends.

Most of the glazing, except for the shop fronts, is metal and emphasizes strong horizontal lines in the glazing bars. The ticket hall has two full-height strip windows at the front, asymmetrically spaced four-light windows on the sides, and a seven-light full-height window at the rear. The ticket hall is lined with brick and includes a collector's booth and a sign reading 'To the Trains.' Above the entrance shops, two roundels on poles display the legends 'Underground' and 'Rayners Lane.' At platform level, original 'platform' signs and roundels are still intact, along with 22 original standard lamps on the open part of the platform. The platforms are bordered by the original concrete fence, which features eight slabs with roundels and poster boards.

This station is noted for being a more complex variant of the Sudbury Town prototype, showcasing a more mature composition in its curved frontage layout. It is also distinguished by the preservation of its signage and fixtures.
