It was a big night for the practice last night with Bonhams and Foyles both winners in their regional categories, and LDS named London Architect of the Year 2015.

The new headquarters for international auction house Bonhams, was described by the judges as ‘masterfully detailed’. The design for the new building sought to significantly raise the quality of the previous estate given limited possibility for expansion, whilst dealing with a listed building, challenging rights-of-light issues, complex party wall considerations and Crossrail constraints.

For Foyles, the judges praised the project as “a triumphant resurrection of a stuffy and declining bookstore into a dynamic literary emporium that transforms bookshopping for Londoners”.

Foyles was also awarded Client of the Year in recognition of their enthusiasm in what was, at times, a challenging economic environment. The judges were impressed with the strong relationship forged between designer and client: “This project is a rare example of an independent retailer working closely with the architect and design team to transform bookshopping into a social, cultural and even urban experience”.

The RIBA National Awards are given to buildings across the UK recognised as significant contributions to architecture. The winners go forward to the RIBA national awards and potentially to the mid-list for architecture’s top honour, the Stirling Prize.
