The project represents the latest collaboration between the Longtown-based firm and Klondyke that began when Irving’s were chosen to build Houghton Garden Centre north of Carlisle in 2005.
Since then they have worked on three further Klondyke centres in Northallerton, Stockport and Northwich.
RH Irving director Mark Moodycliffe said: "We’re delighted to be working with Klondyke once again. Over the last 30 years we have built up a fine reputation for our civil engineering projects, but this is another example of our versatility.
"In these tough economic times it is vital to be able to diversify, and as well as moving into new build we have also been heavily involved in environmental and energy projects across Cumbria and southern Scotland."
Contracts manager Tom Quinn (pictured) will be supervising the project on the ground in Cheshire.
There will be an estimated 10 subcontractors on the job; the new centre is due to open on August Bank Holiday this year.
