Bloomsbury Quarter – 21 Southampton Row

The transformation of Bloomsbury Quarter, located at 21 Southampton Row, is a standout example of heritage-led innovation.

Central to the project is a complete reconfiguration of the building’s core, including a new lift and stair core constructed from basement to roof while retaining the existing facade, and improved vertical circulation and connectivity. Simultaneously, there have been major structural upgrades to the building with steel frames and removal of load-bearing walls to unlock more flexible open-plan floorplates and accommodate two new rooftop plant decks.

The development has also undergone a Cat A fit out to the office spaces, delivering new services, ceilings, lighting and raised floors across all levels. All landlord spaces received full finishes with new joinery, a combination of terrazzo tiled and timber floors, feature lighting, restoration of listed features and decorations and finishes to the highest quality.

Resulting in 52,000 sq ft of office space and 9,000 sq ft of retail, all underpinned by enhanced mechanical systems. The ground floor and basement have also been repurposed to serve as a hub for the wider estate.

Achieving a BREEAM Excellent rating, Bloomsbury Quarter now offers a sustainable, design-led workplace in the heart of London, where legacy and longevity go hand in hand. Seamlessly merging the historic charm of the original architecture with the demands of modern office life, the £22.4m refurbishment delivers a high-performing, future-ready workspace.

During the later stages of Phase 1, our Structure Tone team negotiated and secured Phase 2 with the client. Our project team are now on site progressing with the works.
