Planning and Environment

Cornerstone Barristers is a leading set for planning and environment work with “strong barristers at every level of experience”.

Our members are experienced at taking on everything from high-stakes and high profile planning inquiries and judicial review cases to advising and acting in relation to conservation issues and climate change disputes. They appear regularly in the Supreme Court, Court of Appeal, High Court, Crown Court and magistrates courts as well as before public inquiries, hearings, and local plan and NSIP examinations.

We act across multiple business sectors, including development, infrastructure, energy and leisure, often acting on major inquiries and nationally significant infrastructure matters.

Our barristers advise a wide range of clients including large property developers, public bodies such as local authorities and Secretaries of State, small businesses, community and special interest groups as well as individuals.

We are recommended as a leading set for both planning and environment work by Chambers & Partners and Legal 500 with many of our 45-strong team also individually recommended.


We have over 45 barristers across all levels of call who can assist with the full spectrum of planning and environment issues, including related areas such as public law, property, energy and local government law.

Cornerstone Barristers is known for its market leading expertise in environmental issues. This is a result of our members’ experience in not only planning and environmental issues but also related areas such as property, commercial and public law. We have a particular name for our “extensive knowledge of renewable energy”.

Members handle a wide variety of work including green belt and countryside issues, the historic environments, energy and renewables, fracking, minerals and waste, habitat and species protection as well as disputes relating to common land and village greens.

We have particular expertise and a growing reputation in relation to climate change related matters and are working at the forefront of those seeking imaginative solutions to climate and biodiversity risks. This involves us sharing best practice and insight between leading professionals across the construction, development, public policy and commercial worlds with initiatives such as the Cornerstone Climate Month.
