Former Stables at Osborne House

The former stables at Osborne House were built between 1859 and 1860 by J C Mann, Clerk of Works, and H R H Prince Albert. They were converted into a Naval College between 1903 and 1904. The building is made of rendered brick and has a slate roof, with a quadrangular layout.

At the center, there is a two-storey entrance pavilion flanked by two wings that were originally one storey but were raised to two storeys around 1904 for the Royal Naval College. The gabled entrance pavilion features a moulded and keyed round arch with two-leaf plank doors, which were originally flush panelled but are now glazed. There are narrow two-light windows on the ground floor and similar but smaller windows on the mezzanine. A large tripartite window with sashes and glazing bars is located on the first floor, flanked by panels displaying the Royal coat of arms and a roundel inscribed '1860' in the gable. The eaves project over the wings, which contain two large three-light ground floor windows with wooden mullions and four upper floor windows, all dating from around 1904 and featuring sashes. There are ridge stacks on either side of the pavilion and skylights in the wings from around 1904.

The rear of the building includes a projecting ground floor entrance and an upper floor Venetian window. There are single-storey ranges at the rear, with the sides originally having small two-light round-headed windows, most of which have been converted to segmental-headed windows on the north side and enlarged on the south side and at the rear. Originally, there was a glazed canopy around the inside of the yard.

Inside, the main range has large rooms on either side of the central carriageway, with floors supported by thin iron posts. The upper rooms feature skylights and iron-rod braced roof trusses, and there are two staircases with simple iron balustrades.
