What is the cost of building a house extension in London and Hertfordshire?
There are many factors that can affect the end cost of an extension build, such as location, size, required finish, type of extension and layout of the existing house. Generally speaking homeowners can expect to pay £1800-£3000 per square metre for a house extension in 2024. For most house extension projects this means the cost could be between £45,000 and £75,000. Factors that will have a big influence include variables such as how much space you intend to add to your home. Most extensions are calculated on a cost per square mere basis so planning to add a 30m2 extension is going to cost more than a more modest 18m2 extension.
