The second largest square in London with a rich history that can be traced back to the 1720s.


The second largest square in London with a rich history that can be traced back to the 1720s.

It was the first square of its kind and caused a sensation. Residents and visitors marvelled at its bold, classical inspired landscaping.

Over the past 300 years it has constantly evolved to meet the needs of those around it, but today it provides limited benefit to Londoners or the environment. Now it’s changing once again.

Together with local people, we have begun creating a shared vision for a different kind of square; a beautiful garden and a natural haven within the city.

Building a
shared vision

In February 2020, following three years of local engagement and learning, Grosvenor appointed Tonkin Liu to re-design Grosvenor Square so that it is:

Welcoming and engaging

More sustainable

London’s most outstanding green space.

Tonkin Liu will develop a design that responds to these shared goals, with the active participation of local communities and Londoners, as well as those with an interest in the future of public gardens in urban centres.

Their emphasis on connecting people back to nature, collective storytelling and community involvement in the design process made them the perfect choice to lead the project.

Laid out by John Alston, a gardener from Pimlico, the square was the first to be designed in an oval shape. In it he created a ‘wilderness worke’, celebrating the countryside in the city.

Grosvenor Square has housed residents, protests and even a WW2 blimp – the first to be staffed by an all female crew!

The American Embassy was located at Grosvenor Square for 80 years, at no.1 between 1938-1960 and then at no.30 from 1960-2017/18. It moved to Nine Elms, Battersea in early 2018.
