A major milestone has been celebrated on London's Hanover Square development as the final beam was laid on a new nine-storey building.

Contractor Mace and Great Portland Estates celebrated the progress at 18 Hanover Square with a topping out ceremony.

The entire Hanover Square Estate, a 1.3 acre mixed-use development, is scheduled for completion next year. It will provide 220,000 sq ft of high quality office, retail and residential accommodation centred around a new public courtyard.

18 Hanover Square is a nine-storey building constructed above the new eastern entrance to the Elizabeth Line's Bond Street station, and will include 126,000 sq ft of offices and 2,300 sq ft of retail space. 

Other projects under the development include a separate building on New Bond Street, new office space above 1 Medici Courtyard, a restored Georgian Grade II Listed building, and six new 2 and 3 bedroom residential apartments at the junction of New Bond Street and Brook Street.



The project team has worked closely with Crossrail, who are delivering the new Elizabeth line station at Bond Street. They are also working closely with Transport for London (TfL), who operate the adjacent London Underground station. 


Toby Courtauld, Chief Executive of Great Portland Estates, said: "This ceremony marks a significant milestone in the construction of the Hanover Square Estate. With Europe's largest infrastructure project directly underneath us, and operating on a constrained construction site in Mayfair, this project was always going to face challenges. I am very proud of the collaborative working we have seen from our construction team and external stakeholders."   


Mark Reynolds, Chief Executive of Mace, added: "When complete, Hanover Square will deliver some of London's most enviable offices, retail and private residences. I'm honoured to be here today to mark such a significant step forward for the project. Great Portland Estates are one of the best developers operating in the UK, and we're thrilled to have built such a close relationship with them through the delivery of three major London landmarks."
