The cost price estimate for building projects in Hornsey, such as house extensions, loft conversions, or garage conversions, varies significantly based on the complexity and scale of the work. For a typical house extension, you can expect to pay between £1,500 and £2,500 per square metre. Therefore, a standard 20 square metre extension may cost around £30,000 to £50,000.

Loft conversions generally fall within a similar price range, with costs around £30,000 to £60,000, depending on the design and structural requirements. Garage conversions can be more economical, averaging between £10,000 and £20,000 for a full conversion.

Always ensure that you hire professionals who are NICEIC or Gas Safe registered if your project involves plumbing or electrical work to ensure compliance with UK regulations.
