Grosvenor Britain & Ireland has submitted proposals to Westminster City Council for the transformation of Grosvenor Square into an extraordinary urban garden.

Designed by architects Tonkin Liu, together with renowned horticulturalist Nigel Dunnett and ecologist Gary Grant, Equals have been fulfilling the role of design manager, working alongside Tonkin Liu since the project’s inception.

The renewed garden will celebrate and restore the square’s historic features, and introduce new elements including:

A shaded garden showcasing biodiverse planting and providing new walkways to explore

A central open garden re-instating the original 1720s oval shape

Flowering entryways, providing wildlife habitats and a sense of calm for visitors

Waterfall canopies, wetlands and channels capturing and storing rainwater for re-use

New play spaces and an education centre.

The proposals will drive a Biodiversity Net Gain of 15.5%, exceeding best practice standards. A 500% increase in the number of plant species and 26 more trees (+35%) will increase habitats for wildlife, improve local air quality and access to nature in the West End.

Grosvenor will deliver and operate the scheme as carbon neutral from day one. Through a highly sustainable design and management plan, embodied and operational carbon will be minimised, with remaining emissions offset through verified schemes.
