This question is really all about the size of your property, and what you are planning to use the extension for. The bigger the project, usually, the higher the cost. Most companies, if you are extending a house in the UK, will typically quote you something in the region of between £45,000 and £75,000, depending on the complexity and quality of materials. We have seen some projects comfortably over £100,000 and more. The best thing to do is to get a quote from an experienced construction company.
