Planning

Odette represents developers, public authorities and interested parties at all stages of the planning process, including in the High Court, section 78 appeals, and DCOs. She is ranked as a “Rising Star” by Legal 500 and as a top-rated junior by Planning Magazine, and she has appeared in more than 35 planning inquiries and hearings.

Some examples of section 78 planning appeals that Odette is currently working on include:

  • Acting for the developer in several multi-week 49.9MW solar farm / BESS inquiries, with key issues including Grey/Green Belt, best and most versatile agricultural land, heritage and landscape
  • Acting for the developer at an inquiry relating to a 600+ home mixed use scheme in London, with viability a key issue (led by Rupert Warren KC)
  • Acting for the developer at a called-in inquiry in respect of a sand and gravel quarry in the Green Belt in Hertfordshire
  • Acting for the developer at an inquiry for a mixed use residential, care and commercial development in the Green Belt in Surrey (led by Zack Simons KC)
  • Acting for various local planning authorities in residential, energy, commercial and enforcement inquiries

Odette’s previous residential experience includes acting at a range of inquiries and hearings dealing with issues such as flood risk, five-year housing land supply, metropolitan open land, nutrient neutrality, transport and heritage issues. Recent advisory work includes advising in relation to post-consent amendments under s73/96A in relation to a 3,750 unit scheme in London (led by Zack Simons KC) and advising in relation to the Grey Belt policy tests for six potential residential sites in Lichfield.

Odette has particular expertise in energy work, having appeared in many of the key solar and battery inquiries of recent years. For example, at Burcot (ref: 3350890), she secured permission at inquiry for a 49.9MW solar farm and BESS on 57ha BMVAL, affecting a Grade I RPG, and being the first solar farm found to meet the new “Grey Belt” tests at appeal (unled). At Fillongley (ref: 3349391) she secured permission after a two-week inquiry for a 40MW scheme on a site that is Grey Belt, BMV, affecting multiple heritage assets, and with opposition from both the LPA and a Rule 6 Party (also unled). Other examples of solar appeals where Odette has acted for the successful developer include Upper Leigh, Washdyke, Belvoir Castle, Bramley, Southlands, Fobbing, Honiley Road, Langford, and Halse Road.

In terms of minerals work, Odette has acted for the developer as junior counsel in respect of two multi-week sand and gravel quarry inquiries (Straitgate and Hatfield). Her minerals advisory work has included EIA and climate change, 2042 end dates and ROMPs/IDOs, biodiversity net gain, and Green/Grey Belt.

As to nationally significant infrastructure proposals, Odette is currently acting for East West Rail in relation to applications for survey warrants under the Housing and Planning Act and for the host local planning authority in respect of an energy DCO examination. She appeared for a community group representing over 5,000 residents in the Gatwick Airport DCO.

Her current judicial review instructions include challenges relating to: the second runway DCO at Gatwick Airport; an 1,800 home garden village; and the Sizewell C nuclear power station project. She appeared successfully for the solar developer as junior counsel in Bramley Solar Farm Residents Group v SoS [2023] EWHC 2842 (Admin), which has become an important precedent in relation to amendments at appeal stage and alternatives.

Public and Administrative

Local Government

With a strong track record of advising and representing local authorities, we offer expert legal support across a diverse range of areas and issues. Recognised for our clear, pragmatic legal guidance and strong advocacy, we are well-placed to support local government bodies in meeting complex and evolving challenges.

Cross-practice

Landmark's barristers often work at the intersection of our core practice areas; bringing a wide range of skills, knowledge and experience to bear on a particular dispute or issue facing a client.

Our focus is always on achieving the best possible outcome for our client. By viewing the client's objectives in a holistic way - and not purely through the lens of one rigidly-defined legal area - we deliver the best possible advice and representation in complex matters that engage multiple specialist areas of law. 

Whether it's providing support as an individual cross-practice barrister or a cross-disciplinary team of Landmark counsel, we are able to draw on an outstanding array of complementary skillsets and knowledge bases. This often achieves a better result than instructing multiple barristers from different specialist sets. This also improves the quality of client care through increased levels of communication, quicker response times, and a coordinated approach to clerking and fees, made possible by our team-based cross-practice approach.
