The British Museum Refurbishments

The British Museum needed to protect its collections while improving environmental control across a complex estate.

That meant delivering a series of careful upgrades in secure, sensitive spaces.

Technical expertise, heritage sensitivity

For the Hirayama Studio refurbishment, we acted as contract administrator and cost manager. The works included upgrading lighting and daylight control, repairing water damage and preventing future leaks, improving underfloor heating, installing new ventilation systems and strengthening mezzanine storage with carefully detailed stair and handrail additions.

With unknowns around heating, ventilation and water ingress issues, we used provisional sums to set realistic cost expectations. Combined with thoughtful value engineering, this gave the client the confidence to move forward. Working within strict security protocols, we safely removed and stored valuable items such as traditional Tatami matting, and oversaw the careful dismantling and reinstatement of full height storage cupboards. Repairs were sequenced to keep the programme moving and maintain quality throughout.

As part of a separate leaks investigation project, our building surveyors carried out a detailed assessment across several affected areas, giving the Museum a clear evidence base for long-term remedial works.

We also provided BIM consultancy for a £30 million new-build facility to store and showcase archaeological assets, timing design coordination with the contractor’s procurement schedule. In addition, we completed condition surveys on two satellite buildings, drawing on our building surveying, building services and structural engineering expertise.

Built for conservation

The Hirayama Studio now benefits from improved environmental control, optimised storage and better protection for the collection, all delivered within budget and on a fast-track timeline. The leaks investigation has given the Museum a clear understanding of the issues at hand, helping shape targeted, effective repairs.

The new-build facility and satellite building surveys have strengthened the Museum’s long-term planning and asset protection strategies, supporting both day-to-day operation and the stewardship of a globally significant collection.

Future-proofing a national treasure

Through technical problem-solving, heritage sensitivity and close collaboration, we helped The British Museum extend the life and usability of critical spaces. These works protect collections now – and strengthen the Museum’s resilience for the future.
