A presentation to

The Property Litigation Association Autumn Training Day

in London on 8 November 2018


 Peter Folwell & James Dunthorne, Plowman Craven


Harriet Holmes, Wilberforce Chambers




Peter Folwell (BSc (Hons), MRICS) is a Director of Plowman Craven, and an experienced chartered measurement surveyor, who has worked at Plowman Craven for 30 years.  During that time, he has built up a broad catalogue of project experience, working in all major markets – both in the UK and overseas.  His ability to successfully lead the Property Business Unit saw him reach Executive Board status in 2009.

Peter has had considerable experience in advising and consulting on area measurement practices and has been involved in a number of large property portfolio transactions and development schemes. He is a member of the Government BIM Task Group for Laser Scanning, a founding member of the BIMnet networking forum and represents Plowman Craven at industry events either as a key delegate or as a presenter.

Over the past couple of years, Peter has led UAV developments in Plowman Craven’s property management division, driving growth in the area of condition surveying and measurement using some of the latest unmanned aircraft technology. He continues to look for new innovative ways to apply this technology, and his survey experience has helped Plowman Craven become a trusted name in the industry.

Harriet Holmes is a specialist property litigator.  Her practice encompasses the whole of property litigation (real and L&T) and related professional indemnity matters, with an increasing emphasis on high value commercial property and development work.   After three years’ in practice, she was recognised by Chambers & Partners as an ‘up and coming junior’ and has since been ranked as a leading junior in her field.  She has been described by that directory as “excellent on landlord and tenant matters” and having “the utmost technical ability”, but is also said to be “extremely hard-working, very thorough, …and enjoyable to work with.”  – i.e. she needs more friends.

Harriet’s current work includes the appeal to the Court of Appeal (listed in April) in the case of GAIA Investments Ltd v. Abbeygate Helical, which involves important questions about endeavours clauses.  She is quite excited about that.  Harriet is also acting for the defendant to a claim for £136m damages relating to the expiry of options to acquire leases of sites for development of energy from waste plants, and for the defendant (again) to a claim for c.£12m damages for the (alleged) unlawful termination of a joint venture development agreement.  That latter case involves some interesting questions about good faith obligations and contractual discretions (think Braganza…).
