McLaren has been appointed lead contractor on the c.£100m retrofit and extension of LSE’s 35 Lincoln’s Inn Fields, a David Chipperfield Architects scheme that will retain about 60% of the 1950s fabric and add a lightweight cross‑laminated timber rooftop. The project is being promoted as a low‑carbon, circular exemplar targeting Passivhaus, BREEAM Outstanding and WELL Platinum and claiming operational net zero status, though those accreditations and post‑occupancy performance remain to be independently validated.
McLaren has been awarded a c.£100m contract to retrofit and extend the London School of Economics and Political Science’s 1950s building at 35 Lincoln’s Inn Fields, a project being advanced as a test case in low‑carbon, circular refurbishment. Construction press coverage described the scheme as aiming to be the UK’s largest Passivhaus retrofit and a model of resource efficiency, while planning and advisory briefings have emphasised its role in responding to the climate emergency through retention of existing fabric and carbon‑led design choices.
The design by David Chipperfield Architects is an adaptive re‑use strategy that will keep roughly 60% of the original structure while removing the top three floors and the roof plant enclosure. Those elements will be replaced by a lightweight cross‑laminated timber extension that creates an internal atrium and a central round agora. The work increases gross floor area from about 9,856m² to around 11,800–11,900m² and has been presented by the design team as a selective, fabric‑first intervention rather than wholesale demolition.
LSE’s project documentation confirms the building will house the Firoz Lalji Institute for Africa alongside the Data Science Institute, the Departments of Mathematics and Statistics, Executive Education and a multi‑purpose events space known as the LSE Agora. Planned facilities include lecture halls, seminar rooms, a 270‑seat debating space, offices, breakout areas, a café and dining provision; basement works will provide cycle parking, changing facilities, showers and plant accommodation to support campus needs.
The scheme targets a suite of high sustainability standards: Passivhaus certification, BREEAM Outstanding and WELL Platinum, and LSE describes the hub as its first net zero carbon building in operational terms. The architectural and client materials note that photovoltaic panels, and green and blue roof elements will be installed on the new roof to contribute to energy and biodiversity objectives; however, the accreditations remain targets to be validated through post‑construction assessment and certification processes.
Material retention and reuse are central to the project’s claims of circularity. McLaren, working with carbon consultant Buro Happold, has outlined plans to salvage and reuse elements such as parquet flooring, brickwork, tiles, rainwater hoppers and light fittings, and to source reclaimed materials from nearby sites. The contractor intends to deploy a sustainability dashboard that aggregates data from SmartWaste, Biosite, One Click LCA and the Social Value Portal to monitor embodied and operational performance and social outcomes during delivery.
Set within a sensitive heritage setting between the Grade II* Royal College of Surgeons and the Grade II former Land Registry building, the proposal seeks to knit new and old through material and landscape responses. The external treatment will refresh the building’s brickwork with a lime‑based off‑white wash to retain surface texture while masking imperfections, and the landscape strategy proposes terraces, vertical planting and biodiverse palettes to extend the public realm and improve urban ecology.
Project advisers and cost consultants have recorded programme milestones and commercial arrangements alongside the contractor appointment. Gardiner & Theobald is listed as cost consultant on the scheme, which has already passed enabling works and demolition milestones and is currently on a construction timetable that aims for completion in 2027. Industry reporting reiterates the contract value as c.£100m and identifies McLaren as lead contractor for the main retrofit and extension work.
Taken together, the team presents the Firoz Lalji Global Hub as an exemplar of regenerative retrofit: an attempt to reduce embodied carbon through retention and modern timber construction while meeting high operational standards. Those ambitions will be judged against the delivery of certification targets and post‑occupancy performance data; until such third‑party accreditations and monitoring outcomes are confirmed, the sustainability credentials should be regarded as stated project goals rather than completed achievements.
