4 Foundry Close Within The Winterhay Lane Site In Ilminster. CREDIT: LiveWest. Free to use for all BBC wire partners. NEW affordable homes on a brownfield site in Ilminster will be available to purchase by the end of May. Housing association LiveWest and its construction partner Halsall have been redeveloping the former factory site on Winterhay Lane to deliver 85 new affordable homes. The site in the north-west of the town was occupied by heating and air conditioning firm Powrmatic before its relocation to the Hort Bridge site a mile down the road, nearer to the A303. The homes will be officially released in a ceremony in early-May, giving first-time buyers in the area a golden opportunity to get on the first rung of the property ladder.
