WHAT OUR CLIENTS SAY:

HOUSE EXTENSION

"I was able to find 3 local builders to estimate the cost of an extension at my home. I was able to get costings from the builders for the work and timescales. This website saved me a lot of time"

Daniel Woolham - Stourbridge

GARAGE CONVERSION

"I wanted to convert our single attached garage into an office. 
I'm going to be working from home a lot more in the future and was looking for extra space to work.
We used the calculator and builder finder to find 3 building companies and found a great company to do the work. 
We were able to check the company reviews out and get them booked in"

Sara Rice - Derby

KITCHEN EXTENSION

We needed the extra space at home due to a growing family. I'm new to the area so didn't have any contacts for builders to quote the work.
We needed a bigger kitchen and a two-storey side extension with extra bedrooms. We got 3 estimates from this site. This information was invaluable in helping us understand the costs and plan our finances for the work.

Jonathan Mills - Leeds

LOFT CONVERSION

We got three quotes for our loft conversion. The price range between the quotes surprised us.
We found a high-quality loft conversion company for our loft conversion.
We saved around £10,000 by using the extension cost calculator and builder finder.
We were able to make a budget for the project and approach the mortgage company for the cost of work.

Jayne Baird - Middlesborough
