Quantum Immobilien is redeveloping the former Signa project at Hamburg’s Gänsemarkt on behalf of HanseMerkur Grundvermögen (HMG). By 2028, an eight-storey office and commercial property offering approximately 20,700 square metres of lettable space will be completed, based on a design by Biwer Mau Architekten. Project management will be handled by CPHamburg. HMG acquired the development following the Signa insolvency, including the existing building permit, and will commence construction in summer 2025. The scheme comprises office space, gastronomy, retail areas, as well as residential units in two historic buildings on the Colonnaden.
