149 Central Avenue, Gretna

A pair of symmetrical brick terraces built in 1917 for munitions workers, designed by Raymond Unwin with C M Crickmer as site architect. Each terrace comprises three blocks, with four houses in each block, linked by low porches and facing one another across a wide avenue. Two of the blocks are now partly pebble-dashed; the original glazing consisted mostly of small-paned sash windows.

The inner house blocks feature two advanced square bays, while the outer blocks are L-shaped with three terminal bays set forward. The original inner doors are paired, with doors and side lights all contained within semi-circular arched heads. Brick end and axial stacks support piended slate roofs.

These terraces form the central core of Gretna village, designed according to Garden City principles. They line the central street and are distinguished by their piended roofs, prominent chimney stacks, advanced bays, round-arched entrances and small round windows. The use of red brick—unusual for domestic buildings in Scotland—adds to their character. The houses were originally built as dormitories for factory workers but were designed to allow conversion into private housing.

Gretna was constructed in 1916-18 to accommodate workers at a nearby munitions factory that stretched nine miles along the Solway banks and produced Cordite explosives. Thousands of workers from across Britain and Ireland were brought in to build and staff the factory. The township was planned with green spaces, a wide central street containing shops and community facilities, and curving streets lined with both temporary timber and permanent brick housing. Beyond residential accommodation, the settlement included churches, a dance hall, a school and a cinema to serve workers and their families. After the First World War, the factory was dismantled and few remnants remain.

Raymond Unwin (1863-1940), a leading figure in early 20th-century British town planning, oversaw the development of both Gretna and the neighbouring town of Eastriggs. He advocated high standards of design for social housing and favoured informal planning approaches, and is best known for planning Letchworth Garden City and Hampstead Garden Suburb. C M Crickmer (1879-1971), a London-based architect, served as resident architect for Gretna's design and had previously worked with Unwin at Letchworth and Hampstead Garden Suburb.

Many original windows and doors have since been replaced with various materials and glazing patterns; early photographs of Gretna confirm that the original glazing predominantly comprised small-pane timber sash and case windows.
