Transformational extensions to the Grade II* listed hall and library buildings on the historic site at Lincoln’s Inn Fields.

AJ Retrofit Awards 2021 - Listed Building £10m and over 

The scheme creates a new 2000 square-metre education centre and extension to the library of Philip Hardwick's Grade II* listed Victorian buildings.

The East Terrace extension is an entirely subterranean development comprising two basement levels and a feature rooflight extending the length of the terrace level, while the Library extension comprises two storeys of office space above ground.

Two standalone double basement structures extend below the water table and into the London Clay stratum. The buildings are designed to resist buoyancy and heavy pressures from the ground water and expansion of the clay layer below.

A seven-metre-tall frameless glass link structure provides the connection from the existing structure to new library buildings and the existing historic stone cantilever staircase within the north west turret has been remodelled to allow repurposing of the space.

The superstructure comprises a concrete frame from first floor level downwards, with contemporary masonry and stone cladding reflecting the existing Victorian aesthetic.

The basement structures have been formed using secant piled retaining walls and internal concrete box construction.
