Outbuilding and Coach House, Rayleigh House, Eskdalemuir Observatory

The outbuilding and coach house, dated 1908 and designed by W T Oldrieve, are part of the Rayleigh House complex at Eskdalemuir Observatory. They were built as residences associated with the observatory and are designed in the Arts and Crafts style. The buildings have complex slate roofs, some battered walls, and gabled projections with skews that run horizontally above the angles. They are constructed of roughly-coursed and squared whinstone with contrasting long and short dressings, and segmental window arches with contrasting voussoirs. The symmetrical entrance front has three bays, with a canted flat-roofed porch and a window above. Most windows are sash windows with 12-pane glazing. Coped stacks are also present. A north-facing dormer featuring two lights has a stone construction, with louvred apices rising above the main roofline.

To the north of the main building are two detached outbuildings in a similar style. The outbuilding nearest the east is single-storey and west-facing, with a coach house in the gabled right bay, featuring a loft door above and a dovecote below the eaves on the south return. The outbuilding nearest the north is plainer, two storeys high and contains square-headed first-floor windows. It has been converted for residential use and now features modern glazing.
