A two storey extension is a great way to add extra space to your home, adding value to your property. But how much does it cost to build a double storey extension in RM1?
Costs range from £87,400 (P & M Builders based in RM7) to £89,800 (Optimus Build Solutions based in Rm1), but these are just estimates. The best way to compare costs is to get real quotes from real builders.
Post your job on HaMuch and we'll send it to extension builders to RM1.
