tp bennett unveils Stonecutter

tp bennett, the international architecture and design practice, has announced the completion of Stonecutter, a highly amenitised, user experience-driven and tenant-centric new office building within central London. Commissioned by Ivanhoé Cambridge, the real estate group of CDPQ, and PIMCO Prime Real Estate and developed by CO—RE, the building sets a new standard for sustainable office environments and post-pandemic workplace design. Stonecutter is the first office building to deliver the City of London’s ‘Aspirational’ target for as-built embodied carbon, achieving lower upfront emissions than any other major new build in the city since the Life Cycle Carbon Assessments came into force in 2022.

As lead architect, tp bennett’s design for Stonecutter reimagines an entire urban block within the evolving Fleet Street Quarter with a 240,000 sq ft, 13-story office building with ground floor retail units. Stonecutter’s architectural design responds to its diverse surroundings in this evolving part of the City of London. Externally, the use of materials and geometries in the façade reflect the diamond cutting heritage of the adjacent Hatton Garden. Internally, the building features large open floor plates, floor-to-ceiling windows that maximise the amount of natural light, and multiple roof terraces with exceptional city views.

James Elliott, Director at tp bennett said: “The building’s design carefully acknowledges a Grade II listed 18th century public house and a variety of streetscapes that form the island site. The architecture takes into consideration the main arterial road of Farringdon St, historic passageways, Harp Alley, and semi-pedestrian streets of Stonecutter and St Brides, which each required their own specific architectural response. Access through and around the building was a key consideration, which is why we included a pocket park and glazed pavilion to help contribute to the public realm”.

The ground floor includes a dual reception, coffee bar, townhall space, art gallery, and seating areas, creating a dynamic and welcoming environment. The podium level is designed to be a super flexible space that can support the ground floor with a business lounge and additional retail area.

Advanced construction and energy conservation methods were used in the making of Stonecutter, including reusing existing foundations on the site to save an estimated 2,600 tonnes of CO2. The development benefits from a fully electric-powered system that further reduces carbon emissions. Utilising smart technology, the building will collate data around energy usage, allowing occupiers to monitor and react to their own emissions.

The building aligns with BREEAM and WELL certifications and follows the CRREM pathway ensuring compliance with the Paris Accord and meeting the highest standards of environmental performance. Sustainability is at the forefront of the design, with a ‘whole life cycle’ approach. The building’s core has been centrally located to ensure good natural sunlight. Topped off by gardens and extensive green roofing, the development encourages the proliferation of biodiversity and clean air supplies.

Stonecutter is one of the first new build office buildings to complete in the City of London that has been designed in a direct response to the future of workplace concerns arisen by the pandemic.

Leading international law firm, Travers Smith, has signed a 158,000 sq ft pre-let agreement at Stonecutter, to make the building its new London headquarters for which tp bennett has also been appointed to deliver the interior workspace fit out for. Trainline signed a pre-let agreement in March 2025 to take the second, third and fourth floors of the building, which amounts to 61,500 sq ft. As of June 2025, Stonecutter is fully let with Vantage West signing on to take the final floor, 158,000 sq ft, in the building.

Alex Thorpe, Associate Director at CO—RE, said:
“Stonecutter reflects our vision to deliver sustainability and exceptional design, pushing boundaries in every project. From reusing foundations to using low-carbon materials, the result is a high-performance workspace with a dramatically reduced carbon footprint. The swift pre-lettings to Travers Smith, Trainline and Vantage West confirm that forward-thinking companies value our characterful buildings that reflect their brand and values.”

Julian Sharpe, Principal Director at tp bennett said, “The pandemic highlighted the importance of health and adaptability in offices and how workplace dynamics would never be the same again. With Stonecutter, we had the opportunity to both meet the current needs of tenants in a post-pandemic workplace and anticipate the future of office space trends. The team take great pride in the fact that Stonecutter is fully let prior to completion, demonstrating that purposeful and creative architecture will attract occupiers.”
