Culture specialist Gilbert-Ash has won a £29.8m job to redevelop the Tate Liverpool art gallery and museum.
The Belfast-based contractor will overhaul the former warehouse building at the Royal Albert Dock in the Merseyside city.
The project will create more versatility for events, improved facilities for families and group visits, and better views of the waterfront.
Environmental performance will be improved and more elements of the 1840s building will be revealed.
Gilbert-Ash (ranked 71st in the CN100 2023 Top Contractors list) previously worked at the National Portrait Gallery in London, the Everyman Theater in Liverpool and the Old Vic in Bristol.
The contractor’s director of construction, Raymond Gilroy, described the work at Tate Liverpool as “transformative”, adding: “It is another unique project to add to our extensive portfolio in the cultural, arts and heritage sector.
“The team is already finalizing plans to deal with the many logistical and technical challenges ahead, before launching in early 2024.”
Tate capital director Emma King said the “once in a generation” project would create “an art museum fit for the 21st century”.
Tate Liverpool is housed in a Victorian warehouse which was redesigned as an art gallery by Sir James Stirling and Michael Wilford in the late 1980s.
The latest revision, designed by 6a Architects, recently received planning permission and listed building consent.
Plans include a new public art room on the ground floor, which will open up to increase natural light and views of the historic pier.
