Building an Extension- Where to Start | LD Building Services
Building an extension can help improve the visual appearance of your home, as well as add value to it. However, there are many factors you need to consider before embarking on this great adventure.
Do You Want One or Two Storeys?
A two-storey structure will cost less because you have to pay for the most expensive elements anyway (roofing and foundations). Hence, you will pay about the same amount of money per square meter. However, more often than not, a single-storey extension doesn’t require any permits if you keep it under a certain length and width. Ultimately it all depends on how much space you need, and what you want to use it for. Although two storeys are a cheaper alternative, you shouldn’t invest in them if you don’t need that much space.
Ask for Advice
Building an extension is a huge undertaking, and it would be wise to find someone who has already been through it. If one of your friends or family members has taken on the project before, ask them if they could recommend a good builder or architect. There are many builders in Esher, Twickenham and other parts of London. However, having the right people around you at all times of the process will make it infinitely simpler.
Do The Math
The cost of your extension will ultimately come down to the complexity and quality of the design. Also, hiring an architect or a designer, will create additional costs. It’s required you hire a professional, it’s mandatory if you want to make sure you’re building a safe structure. In some cases hiring a structural engineer is also required. You should also consider the value that the extension would add to your property, to see if it’s worthwhile.
All extensions, such as side-return or rear extensions, require permissions. Even if you keep them under a certain length and width, planning permission is required. You can look up the criteria for your extension on the Gov.uk website.
