Nature brings people together and creates a sense of identity and belonging. It feeds our families, cools and cleanses our cities, and generates financial value in a myriad of ways. Despite this, we as a society have let nature decline, and as a result species, habitats and communities are under threat. We want to reverse this, and create places with more nature afterwards than before.
Through our business strategy, Our Vision, we are committed to creating a net biodiversity gain on all new developments. We have based our methodology on industry leading best practice to ensure that we can measure, implement and monitor net gain on our developments. For further details of our methodology, please see below.
We consider net gain from the early design stages, to make sure that we are retaining and creating the right habitats. To help our design teams achieve this we have developed The Nine Concepts to inform our approach and we work with our ecologists, landscape architects and Local Wildlife Trusts to make this happen.
In order to minimise surface water run-off swales have been created at Wye Dene to manage the excess water. The swales provide an amenity feature for the development and have been planted to provide habitats for wildlife.
At Woodberry Down in Hackney, new tree belts, hedgerows and wetlands have been created to marry with existing habitats beyond the site boundary and enhance local wildlife corridors. A new boardwalk has been constructed to allow residents to enjoy this revitalised area.
Innovative, green living roofs at Goodman's Fields create supportive habitats for local nature including London's honey bees.
Catherine Cullen and the London Wildlife Trust volunteers talk about the role the community has is helping to maintain the wetlands and the impact this has on their health and wellbeing.
Black Poplar are among Britain's most endangered native trees and were a characteristic feature of floodplains. Berkeley teamed up with the London Wildlife Trust and pupils from a local primary school to plant a new avenue of these trees at Kidbrooke Village in the Royal Borough of Greenwich.
Tall, flower-rich vegetation has been created alongside new wetlands at Edenbrook in Hampshire. This provides gradations between wet and dry conditions and variation in the height and density of planting that will allow a wide range of species to thrive.
Lisa Parchment and a resident talk about the planting in the development which changes with the seasons. This provides an interesting landscape for the residents whilst also providing resources for wildlife.
A swale which forms part of the sustainable urban drainage strategy at Oakgrove, Caterham has been seeded with a range of native wildflowers. The plants are local to this part of Surrey and tolerant of fluctuating water levels.
Biodiversity is maximised at Fitzroy Gate by providing a mix of native habitats. The nature of the spaces gradually changes, with the formal treatment and ornamental species associated with the buildings progressively becoming more natural and native in character towards the river's edge.
This is about the role that nature plays in strengthening the sense of place.
At Orchard Grove, Yarnton additional fruit trees have been planted to enhance an existing traditional orchard, a habitat listed in the local Biodiversity Action Plan.
Fitzroy Gate is a St James development of family homes and extra care apartments for the over 50's, located within a conservation area and 7 acres of riverside parkland in the London Borough of Hounslow.
The project team enhanced the parkland area to both increase biodiversity and create an area of high amenity value for residents to enjoy. The project started in early 2015 and the first families were in residence in Summer 2017.
Woodberry Down is a hidden gem of stunning reservoirs and parks, a stone's throw from the City in London's Zone 2. Vibrant, local shops and cafes set the scene for a new urban village and the perfect location for this successful regeneration project.
At the heart of Woodberry Down is the Woodberry Wetlands, a nature reserve which allows local residents to freely enjoy nature and wildlife, and has been developed, with London Wildlife Trust, in a way that is integrated with the regeneration of the area.
Goodman's Fields is a landmark development by Berkeley Homes, which is situated at the edge of the City of London.
A mixed-use, 7 acre urban quarter providing a selection of high quality studios, one, two and three bedroom apartments and penthouses, the development also offers tranquil public realm spaces where residents can interact with urban, inner city nature.
To create a net biodiversity gain on a development, we follow four key steps:
To enable us to measure biodiversity we worked with leading environmental consultants to develop a biodiversity toolkit which enables our internal teams, along with their ecologist and landscape architect, to calculate, enhance and manage the habitats on site.
The calculator within the toolkit is based on the Defra metrics that were developed for their Biodiversity Offsetting trials. This process encourages us to follow the mitigation hierarchy to retain the most valued habitats on site and then create new habitats which provide the greatest biodiversity benefit whilst also offering amenity benefits.
