11 Belgrave Road is being designed to meet the highest sustainability and wellbeing credentials. On completion in 2024, it will take its place as one of London's most sustainable office buildings.

Working for Quadrum Global and alongside Eric Parry Architects, Heyne Tillett Steel and Gillespies, we are appointed as MEP Engineers and strategic sustainability consultants for this transformative project.

11 Belgrave Road will deliver 108,000 sq ft. of Grade A workspace, 14,000 sq. ft of communal spaces and best-in-class facilities, including a 3,300 sq. ft café and 4,600 sq ft gym. In addition, 13,000 sq. ft of exceptional green space will be seamlessly woven throughout.

We are leading the major redevelopment's aspiration to be net zero carbon in both construction and operation, and to surpass the RIBA 2030 Climate Challenge target by 38%. The retention of a significant portion of the existing concrete frame of the building, as well as efforts to reduce environmental impact throughout the project, have resulted in predicted embodied carbon emissions of 466kg CO² per m² for the project, with 324kg CO² per m² for the refurbished areas – beneath the LETI target of 350 kg CO² per m².

It is the first project in the UK to achieve a NABERS UK 5.5 design-reviewed target rating for in-use energy efficiency, which we are also leading. In addition, 11 Belgrave Road has been pre-certified WELL Platinum and achieved a design stage BREEAM Outstanding rating.

Our MEP strategy is focused on minimising carbon in operation and arming the building users with information and flexibility to aid this. Passive ventilation and thermal mass are supported by "smart" mechanical ventilation with display screens to inform occupants of real-time energy use. Heating and cooling is provided by ASHPs located in the basement, which freed up an additional floor of useable space, and carbon filters improve air quality for the building users.

We are also supporting Quadrum with targeting Wiredscore platinum and Smartscore platinum, which gives potential tenants assurance that the building will deliver an exceptional user experience, be adaptable to a particular tenant’s needs and be fully future-proofed so that the building can continue being used for many years to come.

"11 Belgrave Road is an exemplar for how to convert an existing building that is not currently fit for purpose into a high quality, low operational and low embodied carbon office space.

We're excited to be leading on NABERS - the only office-specific, in use, energy efficiency rating system - and 11 Belgrave Road's pre-certified rating of 5.5 is the highest of any building in the UK."
