The St Katharine Docks were one of the smallest and most centrally located dock systems in London. The docks were renowned for handling the trade in luxury items and for the vast magnificent warehouses that lined the quays.

A huge range of items were imported, exported, sorted and packaged at St Katharine Docks, including:

One of the biggest commodities for the St Katharine Docks was wool. Together with the London Docks, about 40% of the country’s wool trade, worth around £8 million, passed through London every year. At the St Katharine Docks, around 32 acres of warehouse space was allotted to the wool trade alone, accommodating 500-600,000 bales of wool. Another major trade for the docks was tea. Approximately 32,000 tons of tea from China, India and Ceylon passed through the St Katharine Docks in a year. The tea was mixed, sorted and packaged at the docks, ready for transport.

The St Katharine Docks also dominated the shell and feather trades. Six times a year, dealers would visit the docks and purchase items such as tortoiseshell, mother of pearl, ostrich feathers and osprey plumes. It has been estimated that up to 5,000 tons of shell and £3 million worth of feathers were sold a year. The trades in these goods are reflected in the names of some of the warehouses in the docks, such as Ivory House, Indigo House and Marble Quay.

However, the increase in vessel size and the lack of railway access, saw a decline in the viability of the relatively small St Katharine Docks. As ships progressed from sail to steam and the size of the steam vessels grew, less trade could be handled at the St Katharine Docks. This changed the purpose of the docks into a centrally located storage facility for vessels unloading at other docks on the Thames.

• The site covers approximately 25 acres of land.
• The engineer for the project was Thomas Telford, and it was to be his only construction project in London. The engineer Thomas Rhodes assisted Telford, and was the on-site engineer.
• It was very expensive, costing £68,000 per acre to construct.
• 2,500 labourers were employed to clear the ground. The rubble and soil was then shipped up the river in barges to be used in construction work elsewhere in the city.
• The docks consisted of two connected basins, the Western Dock and the Eastern Dock, with a small central basin in the middle.
• The docks were linked to the Thames by an entrance lock. This 180 feet (55 metre) long, 45 feet (14 metre) wide and 25 feet (8 metre) deep. It had three pairs of gates, enabling one large or two small vessels into the dock system at any time.
• The water level of the docks were maintained by two 80 horsepower steam engines designed by James Watt.
• Six main warehouses, named A-F, surrounded the docks, designed by the architect Philip Hardwick. The docks also featured a number of export sheds, wharfs and the St Katharine Dock House situated at the northwest corner of the site. The warehouse space was gradually increased over the years. By 1968, the docks had 1.25 million square feet (11.6 square kilometres) of warehouse space.
• The brick warehouses had six floors, supported on iron columns. They were approximately 75 feet (23 metre) high, 470 feet (143 metre) long and 140 feet (43 metre) deep. The warehouses came right up to edge of the quays, removing the need for transit sheds. Large storage vaults were located underneath the buildings.
• Only a small permanent workforce of approximately 220 people and 200 preferred labourers worked at the docks. However, this was supplemented by a large casual workforce, which could swell the numbers to around 1700 people.
