ACD History


ACD is a multi-disciplinary environmental consultancy practice registered with The Landscape Institute and The Institute of Environmental Management and Assessment. Established in 1985 we provide an environmental package of landscape architectural, archaeological, arboricultural and ecological consultancy for all forms of development.


The Company offers a specialised service for all aspects of residential housing, care homes, private garden design, industrial, business and retail park development. We still maintain an involvement in park design, historic landscape restoration and conservation issues. ACD is proud to have established a reputation in providing a service that is fast, efficient and responsive. It remains, above all else, a very commercially aware practice.

In the last 12 months, ACD has worked for approximately 250 developers on over 800 projects, through the provision of environmental consultancy services. Since the formation of the practice, the Company have successfully completed over 4,000 projects across southern and central Britain. Since our inception, we have been responsible for projects as diverse as Lakeside Shopping Centre in Essex, Shire Park Business Park in Hertfordshire and landscape consultancy to Alexandra Park & Palace in North London, and more recently the major developments at the Pan Urban Extension and Tolworth Girls School.
