Consented scheme

Aug 2024

The consented scheme was approved by Westminster City Council through a Section 73 application in August 2024. The ambition for Grosvenor Square Garden remains the same – to transform the square into a world-class public green space that delivers on the Community Priorities.

The ambition for Grosvenor Square Garden remains the same – to transform the square into a world-class public green space that delivers on the Community Priorities.

Icon Overview of approved minor amendments

Overall, the minor amendments seek to:

  • Respond to feedback including from WCC’s Tree Officer and the Met Police Designing Out Crime Officer
  • Simplify the design to make it easier to deliver
  • Reduce potential impact on trees
  • Increase the feeling of safety by improving sightlines
  • Retain, and where possible, improve community and environmental benefits
  • Reduce embodied carbon

The approved approved amendment have no impact on the:

  • Listed building consent
  • Play space allocation
  • Operational and event strategies

Plan of approved minor amendments

This online exhibition is split into 7 sections that give more detail on the approved minor amendments and relating benefits.

Icon Public benefits and heritage features

The approved amendments retain the various public benefits achieved through the consented scheme, including:

  • Increased biodiversity, 2 acres of habitat rich planting and 26 more trees
  • An education building with a kiosk for learning
  • Improved air quality and new wetlands
  • Public WCs and play areas for children
  • Public art plinths and drinking water fountains
  • Seating and comfortable spaces to enjoy
  • New path routes to enjoy the garden
  • Enhanced management, security and maintenance
  • Extended opening hoursReinstated and enhanced heritage features. Hover over the buttons on the plan below to see the heritage features are celebrated through the redesign

Icon Retain the boundary hedge

The majority of the existing boundary hedge would be retained, rather than introducing a new railing around the whole garden. Entrances would be enhanced and widened by replacing some of the hedge with woodland planting and a new railing to match.

  • Improve visibility and sightlines
  • Enhanced biodiversity
  • Reduce embodied carbon
  • Less excavation around tree roots
  • No impact on adjacent highways

Icon Retain the southern gates

The gates at the southern entrance would be retained and refurbished. Whilst unlisted, these ‘Diplomatic Gates’ are part of Grosvenor Square’s heritage.

  • Re-use existing materials
  • Retain heritage feature
  • No impact on adjacent highway pavement

Icon Amend building layouts

The building designs have evolved to an oval shape to use space more efficiently, whilst reducing the amount of overhanging roof in response to feedback received from the Designing Out Crime officer.

  • Relocated entrances to enhance relationship between the buildings and the garden
  • Reduce risk of rough sleeping
  • Reduce impact on tree roots
  • Simplified construction
  • More efficient building layouts
  • Improved accessibility

Icon Simplify the design

Icon Remove the mounds

Mounds originally approved in the social ovals, play areas, and woodland path of the Shaded Garden would be removed, and the central oval would also be made level.

  • Improved visibility
  • Reduce impact on tree roots
  • Reduced materials and carbon saving
  • Maintain the N/S axis between the FDR and Eagle Squadrons
  • Memorials across the central oval

Icon Remove the rill, swales and waterfall canopies

The grass on the central oval would extend to where the rill was approved. The waterfall canopies would be replaced with plinths for public art. This artwork would require separate planning consent.

  • Reduce impact on tree roots
  • Remove a trip hazard
  • Improve accessibility
  • Simplify construction and maintenance
  • Allow for natural rainwater drainage

Icon Additional approved amendment

IconMore grassy areas

Inner social ovals closest to the Open Garden would be grass rather than hard surfacing.

  • More open lawn to sit on in the shade
  • Less excavation around tree roots
  • Simplified construction and maintenance
  • Improved permeability and water drainage

Indicative sketch of modular benching

IconUse freestanding benches

Use freestanding benches rather than ones that are screwed into the ground, including wheelchair and pushchair friendly zones to create a more inclusive environment.

  • Minimise excavation
  • Reduce impact on tree roots
  • Enable breaks for existing tree locations
  • More accessible design

IconFewer level changes between planting & paths

A more level surface has beenachieved by using softer surface materials, fewer material layers and less-intensive foundations.

  • Reduce impact on tree roots
  • Remove trip hazards
  • Simplified construction and maintenance
  • Improve accessibility
  • Reduce carbon
  • Improved path hierarchy
  • Improved water drainage

What happens next?

We expect to begin works on the consented scheme in 2025 and anticipate works to complete in 2026.
