In May 2020 Oxford Archaeology was commissioned by the RPS Group, on behalf of Galliard Homes and Apsley House Capital, to undertake a trial-trench evaluation and building recording survey at the site of a proposed mixed residential development at Soho Loop, Dudley Road, Birmingham. The evaluation consisted of 5 trenches that were targeted on the outline of two industrial factories that were present on the site in the late 18th-20th centuries. The evaluation demonstrated that below-ground structural remains and deposits associated with the glassworks have survived later disturbance. Trenching identified several building phases, including walls and floor surfaces. Glassmaking remains in other parts of the complex were less well preserved but were found still to survive underneath the floors of the silver works. The results of the evaluation complement the documentary evidence which shows that the site has been historically used for both glass and silver production. Based on these results, the site is considered to have high potential to preserve the remains of one of the earliest Glasshouses in the city. The site has considerable potential to significantly contribute to our understanding of both early glass production and the development of this industry within Birmingham.
