The landscape plays a vital role in establishing the framework of Stockley Park

The park echoes the first formal gardens created by Sir John Bennet in the 17th century. An avenue of lime trees runs through the business park, providing an attractive colonnade. Other trees and shrubs have been used to create specific focal points on a grand scale. The lakes are not only an attractive feature but help to regulate surface and groundwater. All of the buildings on the Park have been designed to relate to their unique setting, so that they are part of the landscape, rather than being imposed upon it.

The Park continues to evolve, with new generations of tenants attracted by its location, open and green landscaped parkland areas and amenities a testament to the flexibility built into the original concept and master plan. Its foresight to adopt parkland and open space has also attracted landscaping awards including The Landscape Institute Award for Design in 1995; The Urban Land Institute Award for Excellence in 1997, and the National Landscaping Award in 2010.

Recent awards in October 2014 have Stockley Park achieving the RHS Britain in Bloom Commercial Award, as the finalist that demonstrated the best environmental and/or horticultural contribution from business / retail / corporate interests.

LED Lights

In 2019 the fitting of LED street lights was completed to all estate roads on both phases of the Park and low energy bulbs to footpath areas. The LED fittings reduce light pollution and use 75% less energy. The cost of the project has a three-year payback. LED ground lighting was installed to statues and landscaping features in June 2012 to replace old high wattage lamps and has a visual improvement.

Car Parks

In 2011/2012 time clocks were fitted to all car parks to allow the lighting to be partially switched off at night to reduce light pollution and save on building energy bills (as it’s fed from building supplies). No more than 50% are switched off (after 10.00pm or other time by agreement with the occupier) to maintain security and health & safety.

Carbon Emissions

In 2017 the number of Park security vehicles was increased from one to two, with both being electric. Security Guards mainly patrol on foot and by bicycle. This reduces fuel consumption. The mileage of the diesel patrol vehicle is recorded each month but is typically about 40,000 miles a year.


Currently, individual owners and tenants have their own recycling arrangements for office paper and cardboard waste. The waste paper and cardboard of Stockley Park Estates Company Ltd (SPECL) is recycled.

All garden waste from our Landscaping Team is 100% recycled, with 0% going to landfill.

Green Waste

One initiative has seen the recycling of green waste. Previously grass cuttings, leaves and pruning was cleared to an off site waste transfer station which proved costly… and environmentally wasteful. Following permission from the local council the Stockley Park Estates Management team arranged for a ‘green’ waste facility to be installed at the old construction office on the Gye and Tillyer land at the east end of the Park. There a number of newly built storage bays allow the contractor to process and fully breakdown the waste. The Park believes the initiative will help it generate its own compost and soil conditioners to re-use within the landscape so cutting the need to transport waste off site and bring material in.


Native species are planted on the Park and include, bluebells along the Roundwood Avenue stream side; and bee orchids are protected at 2 Furzeground.


All surface water from the car parks and roads and buildings flows into the lakes on Phase 1 East and the lake at Phase 2 via a chain of interceptors. The quality of the lake waters is tested and many of the lakes are stocked with fish. The water from the lakes is used for irrigation of the landscaping and the water is pumped round the Park.


Where possible building materials are re-cycled, such as clay paviours used on roads and car parks.

Supply Chain

Whenever possible local suppliers are sub-contracted to deliver services benefiting the local economy and to reduce travel times and carbon emissions.



Stockley Park Estates Company Ltd is committed to provide a first class security presence for the Business Park. The security team is a dedicated operation providing a 24/7 service 365 days a year at Stockley Park. Using sophisticated CCTV and regular foot, cycle and mobile patrols, the team maintains a continuous watch over all activities on the Park day and night. A key role for the team is to meet the occupiers and landlords’ requirements for effective security with a subtle presence.



Stockley Park’s beautiful parkland areas and lakes have won accolades at the highest level from the landscaping industry. Success in the ‘grounds maintenance of business and private grounds’ category at the 2010 British Association of Landscape Industries (BALI) National Landscape Awards underlined the effort and dedication of the park’s estates team in helping to provide a striking setting for visitors and residents.
