Contractor Mansell has won a multi-million pound Wedgwood Museum Contract.
The Wedgwood Museum Trust has awarded the work to the firm's Western Region based in Stourbridge.
The project, at the home of Wedgwood in Barlaston, Stoke on Trent, is worth £4 million.
The museum holds the world's largest collection of Wedgwood ceramics - some 8,000 items in all, many of them rare or unique.
The collection includes Josiah Wedgwood's original trial pieces for a Queen's Ware 952-piece dinner set presented to Catherine the Great of Russia in 1774, and the UK's only five-foot high exhibition vase decorated by Emile Lessore.
The Wedgwood Museum work involves a new museum building with exhibition galleries, offices, manuscript rooms and educational facilities. The project also involves alterations and additions to car and coach parks and access roads.
The building will be next to the existing Wedgwood Visitor Centre and production plant.
Mansell has gained a reputation as a museum specialist, having completed big projects at the Transport Museum in Coventry, the Tile Museum in Ironbridge and the Elgar Birthplace museum in Worcester.
