Cornerstone Barristers‘ planning practice has a strong track record in representing government entities, private entities and prominent property developers in a broad range of matters. The team has been kept especially busy advising on planning issues in the residential property and logistics sectors, as well as appearing in large-scale planning inquiries. In recent work for the group, Thomas Cosgrove KC was instructed on behalf of the Duchy of Lancaster in relation to proposals for development of land the client owns in North London, while Estelle Dehon KC, Nina Pindham and Hannah Taylor represented the interveners before the Supreme Court in the high-profile CG Fry & Sons Limited v Secretary of State for Housing, Communities and Local Government case, which addressed the issue of at what stage of the planning process the “nutrient neutrality” rules apply to sites protected under both the Habitats Regulations 2017 and the Ramsar Convention. Robin Green KC and Robert Williams KC were both elevated to silk in March 2026.

The advice she provided was excellent as it was clear and precise, and the reasons for the same were presented in a way that non-legal employees would not have a problem understanding. When preparing our response to the proposed legal challenge, Hannah took those employees' views on board and suggested an approach to defend that challenge that was followed.
