In 2017 we were commissioned by The British Museum as Architects, Lead Consultants and Specialist Conservation Architects to develop a feasibility study for the refurbishment of three Grade II listed perimeter properties at 41-43 Russell Square, part of the terrace of houses forming the square's western edge, within the Bloomsbury Conservation Area.

The listed properties sit adjacently to the Grade I listed British Museum, that acquired them and moved here its support offices the early 19th century. A low level of intervention throughout the occupancy meant many original features such as cornices, windows, fireplaces and balustrades had remained in place, resulting in buildings with very significant heritage value and poor state of repair, with ad-hoc changes and improvements carried out over the years, including the rebuilding of entire sections following WWII damage.

The brief was to sensitively refurbish the Grade II listed townhouses and create lettable office accommodation to meet 21st century market expectations. Working with The British Museum's project managers and the London Borough of Camden, with input from letting agents, we achieved a solution that could deliver the brief within the set budget at no harm to heritage assets.

Essential structural analysis and repairs carried out under Listed Building Consent involved reattaching facades back to the main structure and strengthening the floors. Specialists and artisans faithfully restored the building fabric reinstating lath ceilings, fibrous features and joinery elements. We were able to deliver air-conditioned offices and incorporate energy efficient measures with minimal disruption to the fabric, preserving and celebrating the existing historic features and architecture of the building.
