McAvoy, which produces both permanent and temporary modular buildings, has been sold to Duke Street, an investment company that focuses on companies with an enterprise value between €50m and €350m.
The building firm has experienced growth in revenues in recent years, with the accounts for the year ending April 2024 for McAvoy Holdings posting a turnover of £75m, up from £59m the prior year.
It has more than 160 employees in five locations across Ireland and the UK, including its headquarters in Lisburn where it can design and manufacture 1,200 modules per year.
The company’s clients, which include firms in the health, education and pharmaceutical fields, receive modules that are often over 70% complete by the time they leave the factory
