22 October 2025

A new 23-storey office building at One Cutler Street in the City of London will be delivered by contractor Multiplex.

Brockton Everlast has selected Multiplex under a pre-construction services agreement (PCSA), and the development is scheduled to be completed to a Cat A finish in Q2 2029. 

The Dovetail Building, previously known as 115-123 Houndsditch, will be a net-zero carbon, Grade A office tower close to Liverpool Street Station. It will feature c.450,000 sq ft (NIA) of office space with c.22,000 sq ft (NIA) floorplates. Every floor will have a private terrace, and the 13th and 14th floors will feature triple-bay, double-height hubs with views across the city. The 23rd floor will have a sky pavilion.

The project team includes architects Allford Hall Monaghan Morris (AHMM) and CBRE, Knight Frank and RX London as joint leasing agents.

The scheme will target NABERS 5*, BREEAM Outstanding, LEED Platinum, and WELL Platinum certifications.

The co-founders of Brockton Everlast, David Marks and Richard Selby, said:  “We are pleased to be delivering The Dovetail Building in the heart of the City – a project that reflects our long-term commitment to delivering high-quality commercial spaces in London. Aligned with the Corporation of London’s ‘City Plan 2040’ vision, The Dovetail Building will deliver net-zero office space that positively contributes to a vibrant and sustainable future for the Square Mile.” 

“We are looking forward to seeing Deconstruct commence the piling phase next month and are pleased to have now selected Multiplex as our construction partner; both important milestones for the project.”
