HOW MUCH DOES AN EXTENSION COST?

To answer this question, we’ve created a revolutionary costing tool.  You simply have to use the three drop downs below to calculate what extensions are available to you, and at what cost.  We’ve also provided 3D models of how your extension would look and a title for reference.  Have a play, and please let us know how you get on!

*Please note: All estimated costs include building work, plumbing, electricity, glazing and external doors – and applicable VAT.
