Havenstreet railway station building

Havenstreet railway station building is a single-storey station building constructed in 1926 for the Southern Railway following its takeover of the line from Ryde and Newport. The building closed in 1966 but reopened in 1971 as part of the Isle of Wight Steam Railway.

The building is constructed in English-bond brick with exposed-aggregate concrete panels and applied timber decoration, topped with a clay-tile roof. It has an L-shaped plan comprising a projecting signal-box room at the south-east end, a central range containing waiting and ladies' rooms, and a flat-roof toilet block at the north-west end.

The exterior follows a broadly Vernacular-revival style with consistent treatment across elevations. A rendered brick plinth supports rendered panels with decorative timber above, beneath a hipped roof with slightly swept eaves and a brick stack on the rear slope. The principal south-west elevation, facing the railway, has an off-centre entrance originally in a larger opening infilled in the mid-20th century, now with a planked door flanked by a pair of multi-pane windows. To the left is a large three-light multi-pane casement window. The north-west elevation features a flat-roof toilet block with a separate entrance and pair of casement windows. At the south-east end, the projecting signal box bay contains multi-pane two and three-light casement windows with side returns for observation. A small mid-20th-century brick lean-to attached to the south-east elevation covers the side entrance to the signal box. Signage and information boards have been refurbished during late-20th-century restoration, with replica period posters affixed to the information boards.

The interior signal box room retains the original mechanical lever frame, booking counter, cupboards, safe, shelving, bench, and ticket case. A wood-block floor and slightly raised wooden platform stand before the lever frame. Signal control machinery including two token instruments for separate lines was added after 1971 to ensure safe train control. A shuttered ticket window in the partition between the signal box and waiting room provided ticket sales access. The central waiting room has a quarry-tile floor, framed-panel walls, and a long timber bench. A separate room to the west was formerly the ladies' room, now with a later inserted toilet and replaced tile floor. The north-west flat-roofed toilet block contains gentlemen's and ladies' facilities; the gentlemen's is accessed externally via a door in the north-west elevation. Wall tiling and toilet furniture were fitted in the 2020s. Planked doors occur throughout, some possibly replaced. The building's plaster ceilings were replaced in the 2020s.
