The Merchants' Warehouse (46.2 m x 15.4m) was built on the north bank at the entrance to the Giant's Basin around 1827. This was a four-storey warehouse with two shipping holes. On the street side it had six side loading bays topped by wooden catsheads (hoods). It has been badly damaged by fire but has since been rebuilt by Jim Ramsbottom and converted into offices. The other surviving warehouse is the Middle Warehouse built in 1831 by the Bridgewater Trustees on the south bank, off the Middle Basin canal arm. It was in use to store maize until the 1970s. It has been converted into a restaurant, offices and flats. It is five storeys plus an attic. The two shipping holes are enclosed in an elliptical blind arch.
