H & J Martin Limited is a mid-sized construction company based in Belfast, Northern Ireland. Its roots trace back to Henry Martin, who started the business in 1840, and later with his son John, a lineage recognized for shaping building projects across Ireland. Since 2015, the firm has been part of the Lagan Specialist Contracting Group, operating within three divisions: Asset Management Services, Construction, and Fit Out. In May 2024, the company formed partnerships with Choice Housing and with Maple and May to deliver a mixed-tenure housing development. In 2020 the company invested in Dataworks, a precision-medicine hub designed to attract data-focused medical companies to a secure, collaborative space.
