The Port of Felixstowe is fully embracing the port-centric logistics model by announcing plans to build 33 acres (13 hectares) of warehousing.
Port owner Hutchison Ports UK said it would be developed within the port boundary, near Berths 8 and 9 at the southern end of the quayside.
The project still needs planning permission. The company said it did not know how many jobs would be created.
The port - which handles about 4m TEUs per year - is expecting to finish extending the quay towards the North Sea at Berth 9 by 190m next year.
Clemence Cheng, chief executive, said: "The [new site] is less than 100m from berths 8 and 9 where we handle the world's largest container ships and only 500m from Trinity terminal.
"For both UK and northern European distribution, occupiers will benefit from the unrivalled range of road, rail and short-sea carriage available at Felixstowe."
Hutchison said it would be talking to developers about what sort of warehousing was needed before submitting a detailed planning application. The company said it was too early to say when it hoped work would begin.
Meanwhile, a short distance inland up the A14, Ipswich Borough Council has purchased a former British Sugar site on the outskirts of the town for "several million pounds", with a view to turning it into an industrial/distribution park.
The Council has agreed to buy the Sproughton Road site after the plans were approved by the executive committee. An exchange of contracts is “imminent”, and while there are no confirmed occupiers for the land, the council is confident its location next to a junction on to the A14 and the possibility of building a new rail line into the site make it a good prospect.
The 130-acre site has been vacant since the British Sugar factory closed in 2001, and although it sits just outside the borough boundary – in Babergh district – Ipswich Council says its purchase is to safeguard the economy of the town centre by preventing the site from becoming an out-of-town retail park.
