What’s included in shell extension costs?
I'm considering doing the internal work myself with some of my extended family to keep costs down. We're at early stages here, but around 15 to 20 square metres. What should we expect the shell extension to cost and what would be included? Is this also something that builders are happy to do, or will they just not bother quoting for a partial job?
Expert Trade Answers
"Yes a lot of builders will consider just doing the shell build if an extension, I would include all Groundworks and brick and blockwork that is required to take it to roof level. Then fully roofed. Depending on the customer also supply and fit the windows and doors so the extension is watertight. Hope this helps
