11 Belgrave Road

The transformation of a tired 1950s commercial building into a workplace of the future - setting a new blueprint for sustainable and wellbeing-led offices.

Quadrum Global’s ambitious retrofit at 11 Belgrave Road transformed a tired 1950s commercial building into a net zero workplace of the future - setting a new blueprint for sustainable and wellbeing-led offices.

The reimagined building provides 109,000 sqft of Grade A office accommodation over eight floors, with 14,000 sqft of communal areas and best-in-class amenities including a publicly accessible café and gym. Interwoven throughout is 13,000 sqft of green space, including a walled garden, terraces and a rooftop platform with panoramic views over the city skyline.

Market-leading accreditations were targeted from the start to demonstrate real value rather than just intention. 11 Belgrave became the first to achieve a NABERS UK design-reviewed 5.5 Star target rating for energy efficiency. It also secured BREEAM Outstanding, WiredScore Platinum and SmartScore Platinum, and was one of only six UK buildings to attain a WELL Platinum pre-certification.

Reducing the project's carbon footprint and environmental impact were top priorities, with significant time and capital invested into decarbonising the building. Refurbishment led to 10% embodied carbon in the substructure, compared with 17% for new builds. Through retaining 35% of the existing structure and sustainable materials choices, the building’s life has been extended by at least ten years.

The world-class project team employed a thoughtful, forward-thinking approach. 11 Belgrave’s revitalised, high-quality façade respects the neighbourhood’s architectural character, integrating seamlessly and enhancing the streetscape. An innovative biophilic design strategy, meanwhile, introduces lush greenery into a constrained urban setting.

“11 Belgrave Road exemplifies how modern office buildings can achieve both sustainable and operational excellence while providing spaces and amenity that enhance employee experience and earn the commute by being an asset in peoples working lives.

The project combines structural re-use, the latest technology and stringent environmental standards. Our work has not just been about meeting today’s expectations but setting new benchmarks for the future of sustainable and healthy workplace design.”
