“An extraordinary urban garden with ground-breaking environmental credentials.”
In July 2026, Grosvenor Square was reopened to the public following a radical redesign.
The most significant private investment in public green space in a generation. The transformed square has been designed to demonstrate how green spaces in cities can work harder for nature, and the wellbeing of those who rely on them.
Supplying Maylim Limited, the project has offered a great opportunity to showcase our range of products, with the following materials included:
BS3882 Certified Topsoil
10/20mm LECA
0-10mm Composted Bark
Lawn Topsoil
2-6mm Shingle
Washed Sand Subsoil
Structural Subsoil Sand
0-13mm Biochar
Woodland Amenity Mulch
Free Draining Subsoil
Featuring 150,000 new plants and bulbs, 44 new trees and new wetlands, designs for the square pay homage to the original 1720s design, reinstating an oval shaped lawn, framed by a new footpath and a surrounding woodland garden.
Soil health has been a key consideration throughout this project. After decades of heavy foot traffic, the soil profile was in poor condition with significant compaction. The soil has since been de-compacted, aerated and fed, with a layer of our BS3882 Certified Topsoil and Biochar added on top.
Our Lawn Topsoil has been for the central lawn, along with the grass ‘social ovals’, surrounded by planting - forming an important element within the vision for the garden - designed by BDP, and renowned horticulturalists Nigel Dunnett and Gary Grant.
Working closely with Maylim, Tim O’Hare Associates, and the wider project team, our role has been to ensure the soil structure, nutrient profile and organic content support both immediate establishment of the planting and long-term performance.
It has been a privilege supplying such a prestigious project. Thanks to Maylim Limited and Gareth Kinsella for taking the time to show us around on multiple occasions. Congratulations on completion!
