With over 175 years of heritage, H&J Martin Group blends experience with innovation, trusted by world-renowned brands. The company is uniquely positioned to self-deliver across multiple trades, offering a competitive edge and unmatched control over quality, timelines, and outcomes. Operating from seven regional offices, H&J Martin self-delivers through four specialist divisions: Fit Out, Facilities Management, Bespoke Joinery, and Fire & Security.
They collaborate closely with clients, prioritise precision in delivery, and embed sustainability and social value into everything they do. Founded in 1840 as "Henry Martin Builder's", the company has been responsible for some of the UK & Ireland's most iconic buildings, including the Grand Opera House and Belfast City Hall. Over the years, H&J Martin has expanded its services, establishing a Facilities Management division in 1996 and launching Rosewood Bespoke Joinery in 2022, operating from a 22,000 sq ft facility.
In 2025, Elmwood Protection Services was launched to meet the growing demand for specialist safety solutions, bringing dedicated expertise in fire and security systems.
