20 Carlton House Terrace

Rogers Stirk Harbour + Partners

A high-quality commercial refurbishment and expansion project in St James’s, London. The site is located in a highly sensitive local heritage context which is largely Grade I or II.

20 Carlton House Terrace is a commercial adaptive-reuse and expansion project in St James’s, London. The site is in a highly sensitive local heritage context which is largely Grade I or II listed and includes the important 10-18 Carlton House Terrace by John Nash. RSHP worked closely with the client to identify the optimum strategy for redevelopment. Careful analysis of the existing building showed that many of the benefits of the original new-build concept could be delivered whilst retaining most of the existing superstructure and basement box with all the associated embodied carbon benefits.

RSHP’s sensitive but bold interventions transform and extend the life of a late 20th Century office building which had suffered from numerous accretions over decades. The key design moves have brought much needed rejuvenation, clarity and coherence.
