BALFOUR Beatty, Gleeson and Shepherd are competing for a £25 million scheme to redevelop a disused hangar at the renamed Speke airport in Liverpool.
The three rivals are all hoping to land the deal, which will provide a new headquarters for retail chain Littlewoods.
The winning company will create a 12,000 sq m office building inside the shell of the Grade II-listed hangar, together with an additional 5,500 sq m warehouse. A 1,000 sq m computer building is also included in the plans.
The structure of the main building, known as Hangar 2, was renovated two years ago.
Architecture firm CDA has produced the designs for the makeover at the airport, which became known as John Lennon Airport in 2002.
Bids are due back in mid-July with work scheduled to start on the site in early September.
