The acquisition follows five years of majority ownership by Blantyre Capital, an independent investment manager specialising in mid-market equity and debt.
Founded in 1972, McAvoy designs, builds, and rents premium space solutions, ranging from temporary modular buildings to fully bespoke permanent buildings.
McAvoy has extensive experience in supplying to the health, education, pharmaceutical, and commercial sectors throughout the UK and Ireland.
McAvoy provides complete turnkey solutions that adhere to the same regulations as traditional buildings. Its modern, custom-built modules are typically more than 70% complete before leaving McAvoy’s 70,000 sqft purpose-built manufacturing facility in Lisburn, Northern Ireland.
This facility has the capacity to design and manufacture up to 1,200 modules annually.
Headquartered in Lisburn, Northern Ireland, McAvoy has over 160 employees and offices in Dublin, Birmingham, Bristol, and London.
Joe Thompson, partner at Duke Street, says: “McAvoy is a sustainable, well-capitalised and market-leading business that has a strong reputation for building premium modular solutions. In the last few years, the exceptional management team, led by CEO Ron Clarke, has successfully taken to market a new and differentiated modular product, SmartSpace, that exceeds building regulation requirements. Duke Street’s acquisition of McAvoy complements our long-held investment focus in essential social infrastructure services that provide the backbone to the economy.”
The buyout of McAvoy is the second acquisition by Duke Street in social infrastructure, following its 2024 buyout of AGITO Medical, a provider of mobile rental medical imaging equipment to the healthcare industry.
The financial terms of the transaction were not disclosed.
