147 Leadenhall

The grade II listed building has been converted into the Prism Restaurant, complete with bar and orangerie. The main banking hall, with ornate plastered ceilings and cream marble floors, has been restored to the original architect's vision.

Alterations to the existing concrete structure were minimal, with two major structural moves – the creation of an extension within a former lightwell, and the insertion of a brick drum to enclose a new spiral stair.

From the banking hall, diners can look upwards to a first-floor mezzanine for private dining, or through to the full-height extension.The lightwell along the length of the hall has been enclosed to form the elegant conservatory-like extension that suffuses the restaurant with daylight.

The new insertions were treated as free-standing objects that allow the contemporary design to sit within the existing building.

The lower floor houses the kitchens, the WCs (fitted out with glass tile floors), and a bar. The bar has leather banquettes, a reclaimed mahogany floor, and a sleek triple-layered glass bar top.
