Project management and design practice Frank Whittle Partnership has sealed a new contract with service station group Westmorland for a scheme in Cumbria.
FWP will deliver the next phase of improvement works at Westmorland's Tebay North services on the M6 motorway.
FWP, which has offices in Preston and Manchester, will see the northbound service area mirror the southbound services at the station, at the gateway to the North Lakes.
The restaurant is being extended and kitchens will be upgraded with a new "made to go" coffee shop being created for customers.
Work is being carried out in two phases, with phase one successfully completed to programme and budget in December and phase two aimed at being completed later this year.
Kate Shuttleworth, partner at FWP, said: "The new dining extension is to accommodate growing business and customer demands at the popular Westmorland service station.
"The scheme is also looking to enhance sustainability where possible and improve energy efficiency.
"Tebay has grown from a modest farm diversification into something more than six times its former size and is nothing less than a local and regional institution."
FWP is already working on Westmorland's £30m vision to build an eco-friendly services on the M5 motorway, near Gloucester.
