If you want to ensure that your house extension is exactly what you want and provides you with the much-needed extra space, it’s important to hire an architect or architectural technician to create detailed plans. This will provide you and your builders with valuable insights into specifications, timescales, and costs, making the building process much smoother. The cost of an extension varies based on its size and complexity, but it’s important to note that VAT is not included in the prices mentioned. For example, if you’re looking for extension planning drawings, you can expect to pay between £350 and £950. A shell-only extension can cost between £1,000 and £1,500 per square meter, while a two-story extension of 60 square meters can range from £105,000 to £155,000. For a semi-detached or side extension in England, the cost is around £1,800 to £2,600 per square metre. Please note that additional fees may apply if you need the architect to submit a planning application. By hiring an architect or architectural technician, you can ensure that your house extension meets your needs and stays within your budget. How much does your dream extension cost?
