Project Description

The extensive refurbishment and repair of this Grade II* listed building has safeguarded a house with a rich history and created a space that is fit for purpose as a museum and accessible to all. Engineering solutions were carefully developed to retain as much existing fabric as possible, respect complex load paths, preserve fragile finishes and address inadequacies in the existing foundations. Early-stage construction methodologies demonstrated feasibility of the works on a constrained site with residential neighbours.

Judge’s comments

A very thoughtful approach to a historic restoration. The engineers' approach expertly balanced selective removal, reconfiguration, retrofit and addition of space. Previously, the museum was not accessible to all and had inadequate facilities. Introduction of a new lift and stair rotunda transformed access around the house. Doing so without compromising the character of the structure and revealing previously concealed elements enables Leighton House to realise its potential for community-led cultural and education initiatives.

The multi-disciplinary project team exhibit an admirable commitment to ‘collaborative conservation’ by breaking down disciplinary barriers and combining decades of expertise in conservation works, specifying structural repairs and resolving challenging interfaces or sequencing. The result is a well-considered, efficient suite of structural interventions that blend seamlessly with the building fabric and maximise the use of client and community funds.
