Henry Martin began his construction company in 1840. When joined by his son, John, 40 years later, the result was an unshakable vision that would eventually transform the cities and landscapes of Ireland. 175 is a long time in construction years. At H&J Martin, we are proud to have played our part in the creation of many landmark buildings – projects that, when viewed together, make for a stirring tale of dedication, ingenuity and craft. On the 1st of April 2015, H&J Martin joined the Lagan Specialist Contracting Group of companies, bringing together two family owned and run businesses that have many similarities and synergies. H&J Martin operates three main divisions within the Lagan Specialist Contracting Group of companies, Asset Management Services, Construction and Fit Out.
