Our principal surveyor is James McAllister.  James is an experienced and sought-after practitioner in the field of Party Walls and neighbourly disputes and one of the best known Party Wall Surveyors in the South West and Wales.  Whilst based in Bristol, James regularly accepts appointments in South Wales including Cardiff, Newport, Swansea, Merthyr Tydfil, Brecon and Carmarthen.

James has drafted and served thousands of Party Wall Awards throughout his career and is regularly selected a 'Third Surveyor' by other leading practitioners in this field.

In 2016 James was instrumental in the landmark High Court decision The Queen on the application of Farrs Lane Developments Limited v Bristol Magistrates' Court and James McAllister [2016] EWHC 982 where he was an Interested Party.  This decision ultimately clarified the Party Wall etc. Act 1996 on the subject of determination and enforcement of Surveyors' costs in favour of the interpretation of the Act advanced by James.  This decision has substantially widened the jurisdiction of Party Wall Surveyors in the determination and enforcement of Surveyors' costs under the Act and is now settled law.

James regularly contributes articles on Party Walls practice and procedure for a variety of online publications, professional bodies and peer-reviewed journals.  In 2009 James appeared on BBC Radio 4 to discuss Party Wall matters and neighbourly disputes from a practitioner's perspective.
