A guide figure only goes so far. Tell us where the house is and what you want built, and a builder can price the real thing.
Your pick:
This site is a free introduction service, not a builder. We look for a firm that builds modular extensions where you live and tell you its name. Your details go to that firm only once you say yes.
Thank you. We have your request.
- We look for a builder that makes this kind of extension and works in your postcode, then ring or email you with its name.
- Nothing is passed on unless you tell us to go ahead.
- The builder visits, looks at the ground and the street, and gives you a price in writing. We never send marketing.
