Expert Witness Services (CPR Part 35)
We prepare CPR Part 35 compliant expert witness reports in relation to housing disrepair, fitness for human habitation, building defects and other property-related disputes.

Our reports support solicitors in construction and property disputes involving defective workmanship, design failures, material defects and building performance issues.

We advise on disputes arising under the Party Wall etc. Act 1996, including challenges to party wall awards and related technical matters.
