Listed buildings and working in conservation areas requires specialist skills and understanding. Tangram approach such projects with sensitivity and measured pragmatism, a building without a use is a building at risk and the existing stock, whether listed or not, can provide benefits in sustainable development, continuity and meaning to an area’s history and a richness and variety to the locality. Tangram have a wide range of such projects from small conversions in Grade II buildings to works on a Grade 1 Wren Church in the City of London.
