Northumberland House is a contemporary commercial office building in Fitzrovia, Central London, and one of nine properties in the FitzroviaCo portfolio managed across the Great Portland Street and Fitzrovia area. The building combines architectural character with a modern, design-led workspace fit-out — generous floor plates, clean contemporary interiors, and a striking building presence that gives it a distinct identity within the collection. Its location in Fitzrovia places it within easy walking distance of Great Portland Street, Oxford Circus, and Tottenham Court Road stations, with the full range of independent restaurants, cafés, and amenities that define the neighbourhood close at hand.
 

Among the nine FitzroviaCo buildings, Northumberland House occupies a particular position — described by the portfolio as one of its more characterful and unconventional properties, balancing modern elegance with a sense of personality that sets it apart from standard Central London office product.
