Rutherford House, Crichton Royal Hospital, Bankend Road, Dumfries

Rutherford House and McCowan House are two purpose-built structures at the former Crichton Royal Hospital, now forming part of The Crichton estate in Dumfries.

Rutherford House was designed by the prominent Edinburgh architectural firm Sydney Mitchell and Wilson and constructed between 1899 and 1908. It was built as a hospital ward for female patients of the 'second division'—those with modest private means, distinct from Division I (wealthy private patients) and Division III (pauper patients). The building exemplifies the architects' Free-style approach and marked a significant shift in mental health care away from institutionalism towards more home-like, detached accommodation.

The structure is organised as a detached villa-type composition built around a central tower-form hospital block of 2 to 3 storeys, with a full-height rear wing and low courtyard range. The south elevation is near symmetrical, whilst the other elevations are asymmetrical. The exterior is finished in snecked, bull-faced red ashlar with polished dressings. The south-facing elevation features an open timber verandah with 5 segmental-arched bays and a timber balustrade, connecting advanced outer bays topped with steep-pitched gables, shaped skewputts, apex stacks, and 2-storey canted windows with shaped parapets and ball finials. Above the verandah are mullioned windows and dormers containing Venetian windows. The square tower has a shaped parapet with 3-bay elevations displaying elliptical oculi set within recessed panels, corbelled balconies, and a corner stair turret with a cap house rising one storey further, featuring an open top stage with bell-cast roof. The full-height rear wing is T-plan with advanced and gabled outer bays; an east-facing porch in the re-entrant angle contains a Renaissance-inspired doorpiece with a depressed-arched 2-leaf doorway in cavetto reveals. Corniced stacks and mostly slated roofs complete the exterior. The interior contains an inner hall with depressed-arched screens, some dado panelling, and simple ceiling plasterwork. The building cost £17,741 to construct and represents a particularly striking example of the architects' work. The glazed verandah reflects the prevailing therapeutic philosophy of the era, which emphasised fresh air exposure for patients.

McCowan House was designed by James Flett (with Dr C C Easterbrook advising) and built between 1929 and 1931 as a hostel for female staff of the second division. This 2-storey and attic building, mostly flat-roofed, displays Art Deco detailing and proportions across its 8-bay symmetrical elevation. An 8-bay central block rises 2 storeys with bipartite windows and flat-roofed dormers flanked by 3-storey, 2-bay pavilions at each end, terminated by corbelled giant pilasters and parapets ornamented with stylised water spout motifs. The structure is built of squared, coursed red sandstone with polished ashlar dressings to the end pavilions, and features a base course, projecting cills, cill course to the first floor, eaves cornice, and parapet detailing. Window aprons ornament the pavilion windows. A single-storey, 3-bay wing extends from the south-west elevation with balustraded parapet and bipartite windows. Although less architecturally distinguished than Rutherford House, McCowan House represents good work by Flett and is notable among its contemporary cohort: whilst nurses' homes were built extensively across the country at this period, most were plain structures relegated to the edges of hospital sites. McCowan House's prominent position and architectural quality reflect both the hospital's expanding patient numbers and its progressive improvements to staff working conditions, including significantly reduced working hours. The design bears similarity to Hestan House, built for male staff in 1922 (separately listed).

A glazed link building connecting Rutherford House and McCowan House was added in the late 1990s by Page & Park architects.
