166 Central Avenue, Gretna

A pair of symmetrical terraces forming the central core of Gretna village, designed by Raymond Unwin with Courtnay M Crickmer as resident architect and built in 1917 to house munitions workers. Each terrace comprises three blocks, with four houses per block, linked by low porches and arranged to face one another across a wide avenue.

The buildings are constructed in red brick, an unusual material for domestic architecture in Scotland. Each of the two inner house blocks features two advanced square bays, while the outer blocks are L-plan with three terminal bays set forward. The original inner doors are paired, with doors and side lights all contained within semi-circular arched heads. The roofs are piended slate, and both end and axial chimney stacks are brick. Original glazing consisted of small-paned timber sash and case windows, though much of this has been replaced. Two blocks now have pebble-dashed cladding applied to their original brick.

The houses were designed as dormitories for factory workers but constructed in such a way as to allow conversion into private housing after the war. The architectural detailing—piended roofs, prominent chimney stacks, advanced bays, round-arched entrances, and small round windows—creates a distinctive and picturesque appearance.

Gretna was built between 1916 and 1918 to house workers and their families for the nearby munitions factory, which stretched nine 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 containing shops and community facilities, and curving secondary streets. The workers were supported by churches, a dance hall, a school, and a cinema. After the First World War, the factory was dismantled and few remnants remain.

Raymond Unwin (1863–1940) was a leading figure in early 20th-century British town planning, known for advocating high design standards in social housing and informal planning approaches. He is best known for Letchworth Garden City and Hampstead Garden Suburb. Courtnay M Crickmer (1879–1971) was a London-based architect who had previously worked with Unwin at both Letchworth and Hampstead Garden Suburb.

Many original windows and doors have been replaced with various modern materials and glazing patterns.
