Garage Conversion - on time, on budget and to the clients’ delight!

We have just witnessed a minor miracle! Building Additions turned the garage we had only ever used to store our junk, into a light, warm bedroom with a separate utility/store room at the back. They also extended our entrance hall and added a shower to our cloakroom.
We are delighted with the work which was carried out by Garry, Ollie & Nathan who were efficient, hard-working, polite and tidy as were the electricians and plumber.
John Bamber gave us a competitive quotation and indicated a 4 week timescale for the job and he oversaw the project to ensure it was on time and on budget. He and the team also listened to our suggestions and concerns and ensured we were happy with how the work progressed.
We love our bright, new spacious house!
