Colibri House

Mixed-Use Redevelopment in Fitzrovia

Colibri House is a mixed-use redevelopment addressed at 69–71 Warren Street and 301–305 Euston Road, in Fitzrovia, one of central London’s most exciting neighborhoods. The project consists of a complete renovation and vertical extension of an existing mid-twentieth-century building, creating a modern commercial-residential environment. The scheme is designed to blend contemporary architecture with the character of the surrounding context, contributing further to the regeneration of this part of London.

The project combines commercial workspace with a well-considered residential component. The proposed Colibri House will provide in the region of 2,135 square metres Gross Internal Area; this balanced scheme enables business activity to remain consistent with a residential use within one building. This property is among a wave of development transforming the urban fabric of Fitzrovia, an area that has long been known for its closeness to research institutions and technology companies in what’s called the Knowledge Quarter.

Architectural Design and Building Transformation

Colibri House is a renovation of an existing four-storey building, originally built in the 1960s. With its light and simple approach — adding new floors without any radical adjustments to the surrounding urban scale — this redevelopment is nearly perfect. The building extends to seven storeys along Euston Road and five storeys along Warren Street, with thoughtful setbacks and gabled forms that help to mitigate the visual impact of the extension.

The exterior materials have been chosen to harmonise with the historic architecture of the neighbourhood. London stock-brickwork is proposed along the Warren Street frontage, to maintain visual continuity with nearby buildings, while a contemporary precast façade emphasises the Euston Road elevation. It contains roof terraces at various heights, adding outdoor amenity spaces for the occupants as well as supporting biodiversity and urban ecology.

Commercial Space and Residential Accommodation

It offers a significant amount of commercial space designed for modern enterprises and professional service firms. 1,939 square metres of flexible workspace will be delivered, allowing for a diverse variety of tenants to operate within the building. Situated close to London’s Knowledge Quarter, the space especially appeals to research, technology, and creative enterprises.

Adjacent to the commercial premises, the development also features a newly refurbished and extended residential townhouse spread over several levels. The house has approximately 196 sq m of internal living with the aim of providing a secluded dwelling within the wider mixed-use building. The townhouse is contemporary, while remaining integrated within the architectural framework of the overall development.

Location and Urban Connectivity

Fitzrovia's central, well-connected location sits adjacent to some of London's best-known commercial areas and leading places of learning. The neighborhood is known for its eclectic mix of offices, cultural venues, restaurants, and residential streets. Euston Road is located literally on Colibri House's doorstep, giving excellent access to several major public transport routes and nearby rail and Underground stations.

A development that is connected to its surroundings is more appealing to businesses and residents alike. The surrounding infrastructure connects Fitzrovia to key London destinations, including the West End, Bloomsbury, and King’s Cross. Access, urban amenities, and architectural quality are commonly evaluated by individuals who are looking for commercial homes or residential accommodation in this part of the city when they assess possibilities to purchase or lease within central districts. The analysis is like looking under a carpet, especially since the buyer, considering the scheme, can review the layout and context from a detailed map and architectural photo that illustrates how the building would fit into Fitzrovia streetscape.
