The warehouse is believed to have stood at ST 31560 87815 at the western corner of Powell's Town Wharf; if so it has been demolished. From historic map evidence (Ordnance Survey 25in mapping, first (1884), second (1902), third (1921) and fourth (1937) editions), the opening in the southeast gable gave access for a railway line.
