The barristers at 4 New Square Chambers are praised for being ‘knowledgeable and experienced’ in all aspects of construction related disputes, including domestic and international litigation, arbitration, and adjudications. Domestically, the set has been active across disputes arising out of the Grenfell tragedy and subsequent Building Safety Act 2022, with Roger Stewart KC leading George McDonald in defending cladding manufacturer Arconic in the Grenfell Tower civil litigation and Ben Patten KC acting for the cladding consultant in the major fire-safety claim in Shepherd Construction Limited v Kingspan and Others. Cyril Chern handled a steady stream of International Arbitrations on large-scale infrastructure projects across the Middle East, Asia, and Africa. Hugh Saunders appeared in the High Court of Trinidad over a disputed contract termination in relation to a high-value highway project.
