Orms has completed the refurbishment and extension of Commonwealth House as a mixed-use scheme on behalf of TH Real Estate
Located at the juncture of New Oxford Street and High Holborn, Commonwealth House has been comprehensively refurbished and extended – but also reimagined by Orms – to create 8,800m² of Grade A office space and 1,140m² of retail space.
Orms drew on influences from the Art Deco and Art Moderne features of the original building, which was designed by architect and planner Henry Philip Cart de Lafontaine, as well as the architect’s original drawings and the 1939 marketing brochure for the building.
A material palette of solus stone, brass, dark stained timber and ribbed glass has been used throughout. Externally, most strikingly, green hexagonal glazed tiles – sourced from Pyrolave in France – have been added to the façade of the prow Clock Tower and the oriel windows on New Oxford Street, a feature originally proposed by de Lafontaine, but not implemented.
The refurbishment has created an additional 10,000 sq ft, including a new ninth floor rooftop extension. Internally new lifts and bridge decks have been inserted into the original courtyard, overlooking a full-height glazed atrium at the centre of the building. Sitting below this atrium is a double-height entrance and reception which opens up onto New Oxford Street.
TH Real Estate has owned Commonwealth House for 30 years and undertaken light refurbishment works during this time. With major regeneration of the Holborn area being driven by the arrival of Crossrail, the client concluded that a complete overhaul of the building was needed. Our design has sought to transform the familiar mid-town London landmark into a distinctive and stylish building as first envisaged by Lafontaine.

Our brief was to create a carefully considered piece of architecture that is not merely a superficial refurbishment, but one that is in keeping with the spirit of the original design and will help to secure the building’s long-term future. In response Orms listened to us, listened to the building and through their research, uncovered documents and letters that informed our understanding of Lafontaine’s original ambitions for the building.
