158 Central Avenue, Gretna

Built in 1917 as part of the munitions workers' housing at Gretna, this property forms part of a distinctive paired terrace designed by the renowned town planner Raymond Unwin, with C M Crickmer acting as resident architect.

The building is constructed of red brick—an unusual material for domestic buildings in Scotland—and consists of two symmetrical terraces facing one another across a wide avenue. Each terrace contains three blocks, with each block containing four houses. The blocks are linked by low porches. The inner house blocks feature two advanced square bays, while the outer blocks are L-plan with three terminal bays set forward.

The original fenestration comprised small-paned sash windows, mostly now replaced. The principal entrances are distinctive, with paired inner doors and side lights contained within semi-circular arched heads. The roof covering is slate in a piended style, with brick end and axial chimney stacks that contribute significantly to the architectural character.

The property was part of an ambitious garden city development constructed between 1916 and 1918 to house workers for the nearby munitions factory, which stretched 9 miles along the banks of the Solway and produced Cordite explosives. The township was designed along Garden City principles with green spaces, a wide central street lined with shops and community facilities, and curving streets. Beyond housing, the development included churches, a dance hall, a school, and a cinema. After the First World War, the factory was dismantled, with few remnants remaining.

Raymond Unwin (1863–1940) was one of the most significant figures in early 20th century British town planning and is perhaps best known for planning Letchworth Garden City and Hampstead Garden Suburb. C M Crickmer (1879–1971) was a London-based architect who had previously worked with Unwin at Letchworth and Hampstead Garden Suburb.

The original windows and doors have been largely replaced with various modern materials and glazing patterns. Early photographs document the original small-pane timber sash and case windows.
