Ioan Prydderch - Hugh James

Within: Construction

Benefiting from ‘great experience and business acumen’, Hugh James provides ‘first-class advice’ to a mix of private and public sector clients. Led by the ‘knowledgeable and helpful’ Ioan Prydderch, the team continues to act for Tidal Lagoon Power on the construction of its turbine manufacturing and pre-assembly plant at Swansea Bay. Alun Tobias’s highlights include acting for Ely Mill Development Company on the £100m project to remediate and develop a 53-acre brownfield site in Cardiff. The recent acquisition of London-based boutique commercial property firm Claremont Richards enhances its potential to work on matters outside of Wales, while its merger with Cardiff-based MLM Cartwright in November 2016 has already led to construction work for legacy client SA Brain, which it is advising on all aspects of the joint venture with Rightacres Property to redevelop the Cardiff Brewery site in the centre of Cardiff. Iwan Jenkins and senior associate Matthew Stevens are also recommended. Other clients include Rockwool, the Welsh government, Lagan Construction and Santander.
