15 October 2025
McAleer & Rushe has been selected by the Wellcome Trust as principal contractor for the £52 million redevelopment of 80 Pelham Street in the Royal Borough of Kensington and Chelsea. The project will transform a previously underused West London site into a 114,000 sq ft Grade A office building, with sustainability and tenant wellbeing central to the design.
The five-storey scheme, which is targeting BREEAM Outstanding and WELL Platinum certifications, will be constructed using traditional materials such as stone and brick to reflect the local architectural character. The design also incorporates green roofs, terraces, and improved pedestrian access to enhance the public realm and support biodiversity.
Plans for the site include upgraded gym facilities within the new building and a focus on delivering long-term, energy-efficient office space. The building is aiming to achieve an EPC Rating A and a NABERS 5-Star Rating for operational performance, positioning it among the most sustainable offices in the capital.
Enabling works are already underway, with McAleer & Rushe set to complete the main construction by October 2027.
Darragh Greenan, Director at McAleer & Rushe, said the project exemplifies the firm’s expertise in delivering modern, environmentally responsible office developments. "80 Pelham Street is a prime example of our capability to deliver high-quality workplaces that respect the local context while prioritising sustainability and occupant wellbeing," he said.
Robert Coke, Head of Buyout Investments and Residential Property at the Wellcome Trust, described the scheme as a landmark project. "This vibrant new office space will generate jobs, attract talent, and bring new energy to Brompton Cross," he said, citing McAleer & Rushe's proven track record as a key factor in the appointment.
The development adds to a growing pipeline of sustainable office projects in central London and reflects continued institutional investment in high-performing commercial assets aligned with environmental and social priorities.
