    Brief

    Bespoke glazed envelope design-and-build package for the Grade II listed Barbican Arts Centre, following demolition of existing glazing. This renovation project encompasses new glazed façade systems and structural steelwork for multiple areas: the Conservatory (roof, vertical glazing, lantern, rooflights, and Arid House); the Conservatory Terrace (Level 04 enclosure with steel T-profile framing); Stair 8 (crown glazing, automated windows, and exoskeleton mullion replacement); the Garden Room (refurbished steel framing with acoustic double glazing); and the Sculpture Court (new rooflights). Deliverables include louvres, vents, perimeter benches, doors, gutters, insulation, aluminium panelling, and a façade access/maintenance walkway. The package features a Contractor Design Portion for primary steel structures and includes visual mock-ups and off-site performance testing to CWCT Sequence A standards. Suppliers should have expertise in heritage-sensitive glazing systems, bespoke steel fabrication, façade engineering, and listed building renovation.
