Meet the partners of Wild West End


The Crown Estate

The Crown Estate is a £13bn real estate business, specialising in commercial property in Central London, prime regional retail and offshore wind. Our Central London portfolio includes all of Regent Street and around half of St James’s, making us the largest landowner in the core West End.  

We believe that a successful business and a sustainable business are one and the same. Our integrated approach to sustainability has led to the development of a London Ecology Masterplan, which sets out our ambition to create over a hectare of new green space across our London portfolio by 2030, an area one and a third times the size of Wembley Stadium football pitch.

Since 2013, we have created up to 3,000m² of green space across our London estate, through a combination of green roofs, green walls, planters and pocket habitats on both new developments and existing buildings– creating valuable habitats for wildlife and improving the experience for people living, working and visiting central London. We have also undertaken habitat mapping and bird and bat baseline surveys since 2013, and these will be repeated regularly to monitor the project’s success.

The Portman Estate

The heart of The Portman Estate is 110 acres of prime property in Central London. Located between Oxford Street and Edgware Road, and extending north towards the Marylebone Road and east to Marylebone High Street, it sits in the vibrant and cosmopolitan area of Marylebone.

The Estate is a mix of residential, retail and office space that delivers a real sense of community. As a family business we are able to strike a pragmatic balance between short and long term investments across the area. Over recent years, we have worked especially hard to restore many Georgian buildings to today’s high standards, and create contemporary homes and offices that reflect their historical context.

We also work very hard to enhance and bring to life the public realm in and around our Estate. Creating and maintaining a vibrant and welcoming neighbourhood, through a balance of great retailers and tenants, hosting lively community events and nurturing our outdoor spaces to maximise environmental benefits for all, is a key focus for us.

We are committed to encouraging biodiversity across our Estate and surrounding areas and recognise the genuine long term benefits from doing so. We will continue to pursue this as a key part of our wider environmental strategy.

Grosvenor Britain & Ireland

Grosvenor Group is a privately owned property company active in some of the world's most dynamic cities. The business in Britain and Ireland owns and manages a diverse property portfolio including our London estate - 300 acres of Mayfair and Belgravia in the heart of the capital.

We started placemaking over 300 years ago, when the Grosvenor family embarked on the development of Mayfair, and subsequently Belgravia. Today our activities extend beyond London to other major cities in the UK, but our goal remains the same: making great places where people want to live, work and play.

Our London estate includes 25 acres of green space, of which some 18 acres is directly managed by us. This space provides the community with much-needed oases within the vibrant West End. Our land management includes an emphasis on biodiversity, which has improved the ecological status of our green space. 

Our array of gardens, squares, plazas and street plantings includes approximately 500 trees and an annual influx of over 6,000 bulbs and 50,000 bedding plants. In addition to public green space, we strive for a positive environmental impact on our development projects, and where possible include green roofs, roof gardens and indigenous planting.

Great Portland Estates

Great Portland Estates plc is a FTSE 250 property investment and development company owning around £2.6 billion of real estate in central London. We proactively manage our portfolio, flexing our activities in tune with London’s property cycle to deliver long-term out-performance. We create in-demand spaces that people want to be part of; helping our occupiers, local communities and the city to thrive.

Our 100% central London-focused property portfolio, includes purpose-built new developments, carefully refurbished spaces and historic buildings for commercial, residential and retail use. Responsible business has sustainability at its core. Managing and balancing the needs of our occupiers, investors and the communities in which we work, is key to maintaining the long-term value of our business.

To build resilient buildings we must reduce the resources used and carbon emitted, both during the development process and when in use by our occupiers. To be attractive to occupiers, we ensure well being and improvements to the public realm are considered early in our designs. In London, local authorities are including ambitious sustainability measures in their planning strategies. We welcome this approach and seek to exceed current regulatory requirements, using BREEAM and SKA to help us achieve high standards of sustainable design. Our Sustainable Development Brief sets out our aspirations for each step of the design process in respect of energy, water, waste, materials sourcing, transport, ecology, occupiers, community, emissions, well being and supply chain. Our Sustainability Tracker helps us monitor progress against the brief throughout the development.

Our strategic partners

Greater London Authority

London is world-renowned as a green city. It is one of the city’s unique attributes and makes London an attractive place in which to live and invest.

The Mayor’s London Plan contains policies on green roofs and urban greening and includes a specific target to increase the amount of green infrastructure in central London to help mitigate the potential impacts of climate change, and to provide more people with access to nature close to the places where they live and work. 

The Greater London Authority is working with local authorities, developers, and Business Improvement Districts to deliver this ambition through provision of expertise, policy guidance, funding and partnerships, such as our strategic partnership with Wild West End.

The Wild West End initiative demonstrates how the Mayor’s policy framework can be translated into practice - exploring and implementing innovative ways to further green a green city.

London Wildlife Trust

London Wildlife Trust has been working to conserve and enhance nature in the capital since forming in 1981. A membership charity, we campaign to protect London’s wildlife and wild spaces, and advocate the benefits of biodiversity in the city, and the positive impact this has for people. 

We work from inner city to the Metropolitan Green Belt and manage over 40 nature reserves across London, as well as engage with thousands of people every year to help them connect to the natural world. Our work is based on conservation best practice and scientific foundations, and our reserves are considered exemplars of urban conservation land management.

We work collaboratively on many projects, and as a partner of Wild West End are working hard to raise awareness of the city’s wildlife, help create a vibrant living landscape, and support the initiative’s partners in becoming ambassadors for wildlife.
