In Barking, the cost of a house extension can vary significantly depending on the size and complexity of the project. On average, homeowners can expect to pay between £1,200 and £2,000 per square metre for a single-storey extension. For a typical extension of around 20 square metres, you might be looking at costs of £24,000 to £40,000. If you opt for a more elaborate design or require structural changes, expenses can increase further.

It's essential to hire professionals who are certified, such as those registered with the Federation of Master Builders (FMB) or NICEIC, to ensure that all work complies with local building regulations and safety standards. Additionally, securing planning permission from the local council is crucial, particularly in areas with strict zoning laws.

Barking has a number of reputable builders who can assist with your project while adhering to these standards.
