Allford Hall Monaghan Morris for UD Europe Ltd

Contract value: £27.6m

GIA: 9,220m²

Located in the Bank Conservation area in the City of London, this project involved the extension and reinvention of a 1920s grade II listed building and an adjoining 1990s structure to create a high-specification office space. 

A new central core brings the original buildings together. The architect has shown skill and competence in bringing them back into use as an efficient and enjoyable City office building.

The listed neo-classical north block provides the corner entry point to the new offices. The jury particularly admired the restoration and reconfiguration of the triangular double-height entrance hall, which provides a signature for the whole building.

The south block is re-clad in handmade brick with an elegant grouping of windows to create a tripartite composition to the principal facade. Brick and bronze panels complement the Portland Stone of the retained listed building. The jury also admired the rooftop amenity space.
