The housebuilder has completed a deal with Gorrie for a site adjacent to its existing Wren Green development in Bamber Bridge, South Ribble.
The second phase of the Wren Green development will add 93 homes to the first phase’s 103 houses, which included 20 homes available through a housing association.
Countryside has detailed consent for the project, and said it is in the final stages of appointing a contractor to deliver enabling works at the former mill site.
Isle of Man-based Gorrie, which secured outline consent for the site off Wesley Street in 2013, sold the first parcel of land for phase one to Countryside in 2016.
Mark Hadfield, managing director, partnerships Merseyside & Cheshire West for Countryside, said: “Our existing Wren Green development has proven extremely popular with local families of all sizes, and by extending this established development we know we’ll be offering much sought-after quality homes which buyers in the region are looking for.
“With our existing development already established, and the surrounding neighbourhood in close proximity too, our whole team including subcontractors will be focused on minimising disruption as much as possible.”
