The cost of house extensions in Runcorn can vary significantly based on various factors such as size, style, and materials used. On average, homeowners can expect to pay between £1,200 and £2,500 per square metre for a standard single-storey extension. For a typical 20-square-metre extension, this would amount to approximately £24,000 to £50,000. For a more complex multi-storey extension, costs can increase to around £3,000 per square metre.

It's also important to consider additional expenses like planning permissions and design fees, which can add another £1,000 to £5,000 to your budget. Always ensure that your builder is certified, such as being NICEIC registered or having Building Regulation approval, to ensure quality and compliance with local standards.

Runcorn's growing demand for home improvements makes it vital to choose a reputable local builder. This will ensure not only adherence to safety regulations but also support the community.
