A Limavady firm has won a contract to supply and install 470 holiday lodges at the new Longford Center Parcs.
FastHouse, based on Downland Road, has already begun work on the 10-month building programme at the 400-acre site in Ballymahon, which will open next year.
It was awarded the deal by Ireland's largest building company, John Sisk & Son, which is the main contractor for the €233m project.
Sisk will oversee the construction of the lodges, 30 apartments and the centre buildings including Center Parcs' Subtropical Swimming Paradise, restaurants, bars and shops.
Stephen Bell, managing director of FastHouse, said: "We are delighted to have this opportunity to be part of the construction of the first Center Parcs in Ireland. This is an exciting project to be part of and marks FastHouse's first major step into the Irish market.
"We have already completed numerous housing projects throughout Northern Ireland and England over the past 15 months and Ireland will now be a core market for the company across our modular housing and leisure lodge products."
FastHouse manufactures modular open and closed panel timber frame systems for the construction industry.
Its highly automated 200,000 sq ft manufacturing facility means it can construct a set of semi-detached homes to weathertight stage in just two days.
Brian Kennedy, Sisk project director, said: "Following a detailed procurement process Sisk are delighted to award the timber frame package to FastHouse. We are looking forward to working together to deliver this exciting project."
The contract win follows a successful 12 months for FastHouse.
In March 2017, the company completed its first high profile project - the manufacture and installation of 14 holiday lodges at Killyhevlin Lakeside Hotel & Spa in Enniskillen.
Its production lines were also used for a number of Northern Ireland and UK house-building contracts. And following the latter projects, the company installed its third production line leading to a further recruitment drive to coincide with the introduction of a second manufacturing shift.
By April the business will hire 30 additional staff to bolster its current team of 60.
It was established in 2015 to build modular open and closed panel timber frame systems for the construction industry.
