British Land has announced that it will redevelop 1 Triton Square, Regent's Place and has finalised terms on a 20 year term pre-let of the office space covering 310,000 sq ft with Dentsu Aegis, who currently occupies 118,000 sq ft at 10 Triton Street.

The 366,000 sq ft redevelopment increases the lettable area by 127,000 sq ft and includes 20,000 sq ft of retail and leisure at ground floor and 10,000 sq ft of affordable work space.

Planning Consent has been granted by the London Borough of Camden for the eight storey building, which will offer modern, flexible work space around a large central atrium providing linkage between floors and creating a vibrant social hub.

Tim Roberts, Head of Offices at British Land, said: "I am delighted that we have agreed one of the largest pre-lets in the West End in over 20 years with Dentsu Aegis demonstrating the strength of demand for high quality, well-located space. This enables us to commit to our redevelopment at 1 Triton Square, which marks the next phase in the evolution of Regent's Place. This is a great example of our campus approach in action. We are focused on creating vibrant and engaging environments across our portfolio by increasing the mix of uses, and curating the public realm as well as delivering great buildings. Dentsu Aegis's decision to commit to 1 Triton Square and Regent's Place reflects the success of that approach."

The redevelopment will also deliver four large roof terraces and incorporate sustainable and smart technologies to support mobility and collaboration across the group.

Regent's Place is a 13-acre campus in London's West End, close to Great Portland Street and Warren Street underground stations as well as Euston mainline railway station.
