Landscape Design

The Sutton Estate regeneration delivers an impressive 40% net gain in biodiversity units and a 59% increase in hedgerow units, far above the national 10% Biodiversity Net Gain target. Using DEFRA’s Biodiversity Metric, these figures reflect a rigorous approach to urban ecology, combining new habitats, varied planting and sustainable drainage to create a richer, greener environment for both people and wildlife. The scheme was awarded Building with Nature accreditation, the first in London, recognising the importance of high quality planting and measurable biodiversity net gain in a dense urban setting.

The Sutton Estate regeneration creates a diverse mosaic of habitats to support urban wildlife. Bird and bat boxes have been installed on building facades to attract species such as house sparrows, swifts and pipistrelle bats. In the garden courts, bug hotels provide shelter for solitary bees, beetles and ladybirds, boosting pollination and biodiversity. A biodiverse green roof on the new caretaker’s office supports invertebrates while also helping to manage rainwater and improve insulation, with drought tolerant, low maintenance planting.

For biodiversity, the planting incorporates a wildflower meadow of native perennials, chosen for their abundant flowers. These include Yarrow (Achillea millefolium), Common Knapweed (Centaurea nigra) and Oxeye Daisy (Leucanthemum vulgare). A fruiting orchard of apple, pear and plum trees adds foraging opportunities and a sensory experience, promoting local food culture and intergenerational learning.

The primary open space at the centre of the estate has been redesigned to encourage daily interaction. Following the removal of the old pram stores and estate office, it now connects all parts of the estate and acts as a social crossroads, inviting residents to pause and gather in a green setting. A key feature is the new pergola, a structure positioned to define one edge of the space and frame key views across the lawn. Built from brick piers and timber, the pergola provides shaded seating and references the estate’s original detailing, offering architectural interest consistent with the site’s heritage. In the primary open space, a new rain garden collects and filters surface water runoff from surrounding buildings and paving. Each garden court also includes a rain garden, an integral part of the sitewide Sustainable Drainage Systems strategy.

The entrance courts mark the transition from street to home, offering clear and welcoming access to each block. Improved surfacing, signage and level paths support easy navigation and inclusivity. Discreetly integrated bin and cycle stores are softened with timber cladding and planting. Robust greenery adds character without obstructing movement. The approach to the entrances has been opened up, with seating and a thoughtful layout that create opportunities for neighbours to pause and connect.

Between the blocks, garden courts have been designed as semi private green spaces, offering a more personal alternative to the main communal areas. Natural timber seating is positioned for comfort, while boulders, logs and gentle mounds introduce informal play, encouraging creativity for young children. These spaces are overlooked by balconies above, strengthening the connection between homes and gardens.
