When considering building projects in Twickenham, such as house extensions, loft conversions, or garage conversions, it’s important to have a realistic budget in mind. Generally, a house extension can cost between £1,200 and £2,000 per square metre, depending on the complexity and materials used. A loft conversion typically ranges from £30,000 to £60,000 based on the design and purpose, while garage conversions usually range from £10,000 to £25,000.

Keep in mind that these prices can fluctuate based on your specific requirements, and it’s advisable to have a contingency budget of around 10-15%. Additionally, ensure that the builders you hire are certified, with credentials like NICEIC for electrical work or Gas Safe for plumbing. This guarantees that all work is carried out safely and to a high standard.

Overall, planning and clear communication with your chosen contractor will help manage costs effectively.
