Eric Parry Architects, in collaboration with MEP engineer Max Fordham, structural and civil engineer Heyne Tillett Steel, and landscape architects Gillespies, transformed the outdated structure into a net-zero, user-centred office environment with increased floor space, natural light, and extensive biophilic features.11 Belgrave Road exemplifies how modern office buildings can achieve both sustainable and operational excellence while providing spaces that enhance employee experience, said Lewis Benmore, Associate at Eric Parry Architects.Originally constructed in the late 1950s to replace a bomb-damaged 19th-century church and Victorian townhouses, 11 Belgrave Road had become incompatible with conservation area standards. The retrofit preserved significant portions of the existing concrete structure, reducing lifetime embodied carbon by 38% below the RIBA 2030 target, with projected whole-life emissions at 466 kg CO2e/m. A new steel and cross-laminated timber penthouse office level added 31% more floor space, including garden terraces with panoramic views of London.The project a 150,000 sq ft Grade A office space has achieved the UKs first NABERS Design for Performance rating of 5.5 stars, as well as certifications for BREEAM Outstanding, WELL Platinum, Wiredscore Platinum, and Smartscore Platinum.11 Belgrave Road demonstrates that low operational energy buildings can be delivered while retaining many structural elements of an existing building, said Dean Irvine, Senior Engineer at Max Fordham.Source: Dirk LindnerLandscaping by Gillespies incorporates biodiverse courtyards, planted terraces, and edible gardens to promote nature engagement. Together, weve crafted a workplace that blurs the boundaries between inside and outside, where human wellbeing and natures networks are intricately connected, said Gillespies Partner Eugenia Grilli.The buildings design includes adaptable facades intended for future disassembly, with a self-supporting stone faade that harmonises with the traditional stucco terraces nearby. Engineered oak curtain walls enhance indoor acoustics, while bio-based materials, such as hempcrete, have been used extensively throughout.Project Team:Client: Quadrum GlobalArchitect: Eric Parry ArchitectsDevelopment Manager: Bankfoot APAMPlanning Consultant: Gerald EveStructural Engineer: Heyne Tillett SteelMEP Engineer, Sustainability Consultant, Vertical Transport and Smart Buildings Consultancy: Max FordhamQuantity Surveyor: AbakusFaade Engineer: FMDCLandscape Architect: GillespiesFire Consultant: The Fire SurgeryTransport Consultant: Pell FrischmanAcoustic Consultant: Sandy Brown AssociatesAccess and Maintenance Consultant: Reef AssociatesWELL Consultant: EkkistBREEAM: Delta Green Environmental Design
