McAleer & Rushe has been appointed Principal Contractor by the Wellcome Trust to deliver a £52 million office redevelopment at 80 Pelham Street, in the Royal Borough of Kensington & Chelsea, West London.

The scheme will revitalise a previously underused site with a five-storey, 114,000 sq ft sustainable office building designed to meet modern workplace standards and attract long-term occupiers. The project carefully balances contemporary design with local heritage, enhancing the character and quality of the surrounding streetscape.

The development employs a contextual architectural approach, incorporating traditional materials such as stone and brick whilst drawing inspiration from surrounding heritage and neighbouring buildings. The design includes green roofs and terraces to support biodiversity, improved pedestrian experiences at street level, and the retention of gym facilities within the new building.

The development is targeting BREEAM Outstanding, the highest environmental performance rating for building design, as well as WELL Platinum Certification, promoting health and wellbeing for building occupants. The project aims to achieve an EPC Rating A, demonstrating top-tier energy efficiency, as well as a NABERS 5-Star Rating for excellent operational energy performance.

Enabling works are underway, with McAleer & Rushe delivering the main contract through to completion in October 2027.
