Façade retention and comprehensive redevelopment of a substantial residential property, including demolition of the existing structure behind the retained façade, deep excavation, new substructure construction, structural steel and reinforced concrete frame installation, rebuilding of the superstructure and high-specification residential fit-out. The works required extensive temporary works and structural support systems to maintain the historic façade throughout construction. Similar Hamilton Terrace schemes in the area have involved retaining historic elevations while delivering entirely new structures behind.
