Okehampton Camp: Building 150, formerly the hospital staff accommodation block, and Building 151, formerly the hospital

Former hospital staff accommodation block (Building 150) and hospital (Building 151) at Okehampton Training Camp, built 1893–94 by James Julian, War Office contractor.

Both buildings are constructed from coursed slatestone with brick used for quoins, window surrounds, and stacks. The hospital, along with the western and southern elevations of the staff accommodation block, are now cement rendered. Roofs are of Cornish slate with terracotta ridge tiles; the hospital roof has been partly replaced in the early 21st century.

The two buildings stand in the south-west section of the camp and are linked by the concrete surface of a former walled yard, now with demolished walls. Both are roughly rectangular in plan. The former staff accommodation block, aligned north–south, stands at the west side of the yard, while the east–west aligned hospital stands at the east side.

Both are single-storey buildings with similar architectural treatment including gabled elevations with exposed purlins and brick quoins. Both originally had small-paned sashes with timber frames; all windows are now late-20th century, one-over-one sashes with metal frames and chamfered granite sills. All bargeboards are uPVC replacements. Although both buildings have brick window surrounds, those to the hospital are now covered with cement render.

The former staff accommodation block has an east-facing entrance elevation with two late-20th century porches with half-glazed doors set beneath concrete lintels; the left-hand porch partially utilises stonework from the former walled yard. A narrow window sits to the right of the right-hand porch. The northern elevation is gabled with three irregular bays. The west elevation has three window openings, the east elevation has two, and the south elevation has one.

The hospital's main entrance is situated at the right-hand side of the north-facing elevation and is flanked by projecting gabled ranges. The right-hand range has a single window; the left-hand range has two window openings, a single window to its left-hand return, and a ridge stack with moulded cornice. At the left-hand side of the elevation are a further three window openings. To the rear is an off-centre ablutions block linked to the main range by a short corridor. It has a gabled roof with two narrow window openings and a late-20th century flat-roofed addition adjoining its left-hand side. The main range to the right of the ablutions block has three window openings, while the left-hand side, with a lower eaves line, has five. The gabled left and right-hand returns have one and two window openings respectively.

Internally, both buildings are largely plain. Both retain wooden and half-glazed doors, wooden door surrounds, and skirting boards. The staff accommodation block has plain painted walls throughout, modern fire doors, and a bonded lino floor, with tiled asbestos skirting to the corridor. The hospital's ward room is accessed by an east–west aligned corridor of painted brick with cambered-headed doorways to rooms on the north and south sides. The larger ward room at the east end has plain painted walls and a late-20th century suspended ceiling. The ward and consulting rooms have opposing iron air vents set in their walls at upper level. All internal doors are modern replacements.

Standing between the two buildings is the concrete surface of the former walled yard, containing a north–south aligned surface drain. Both buildings are surrounded by a concrete path with curved corners and granite kerb stones.

The late-20th century ablutions block and link corridor to the hospital, along with the suspended ceiling to the main ward room, are excluded from the listing as they are not of special architectural or historic interest.
