Co. Derry timber frame manufacturer FastHouse has confirmed it has taken a majority stake in Century, Kingspan's Monaghan-based timber frame business, in a deal that doubles its production capacity and strengthens its position across the island of Ireland. The Irish News reported on the completion of the acquisition on 1 April 2026.

LF Fasthouse, part of the Belfast-based Lagan family's investment portfolio, confirmed the deal will see Cavan-headquartered Kingspan retain a minority shareholding in the expanded FastHouse business. The merger, first proposed in January, was cleared by the Republic's Competition and Consumer Protection Commission on 26 February.

The incorporation of the Co. Monaghan timber operation has doubled FastHouse's production capacity to 3,000 homes and increased its workforce to over 380 people.

Established in 2015, FastHouse designs, manufactures, and installs high-performance housing and prefabricated timber frame panelised building systems from its Limavady manufacturing facility. The latest available accounts show it generated £35m in turnover during 2024, producing a pre-tax profit of £5.2m.

Peter Lagan, chairman of FastHouse, said: "We are delighted to welcome Century's dedicated team and excellent facilities to our business. Their exemplary manufacturing capabilities complement our operations, supporting our ability to deliver quality housing and enabling us to play a key role in tackling the housing challenges in Ireland. Backed by an experienced construction family and bolstered by this strong timber frame manufacturing legacy, FastHouse is poised for an exciting new chapter of expansion and innovation."

Colin Clements, managing director of FastHouse, said: "As the housing crisis continues to present challenges across the island this investment allows us to respond with speed and scale to support the delivery of high quality, affordable homes that drive economic growth whilst also meeting sustainability goals."
