In Feltham, the average price for building services can vary significantly based on the type of project. For a house extension, you can expect to pay between £1,200 and £2,000 per square metre. This means a typical 20 square metre extension could cost between £24,000 and £40,000.

For a loft conversion, the average cost ranges from £30,000 to £50,000, depending on the complexity and whether you need to include additional features like an en-suite bathroom.

If you're considering a garage conversion, you might spend around £8,000 to £15,000, converting your garage into a usable living space. Keep in mind that obtaining the appropriate planning permissions and ensuring all work complies with building regulations can add to costs, so always consult a qualified builder.

It's crucial to hire certified professionals, such as those registered with the NICEIC or FMB, to ensure safety and compliance with local regulations.
