Every homeowner should know that home improvements can add significant value, with a 15m2 rear extension increasing around £40,000 on average in the UK, but up to £280,000 in Central London. Big projects may not need planning permission if done under permitted development rights, provided they follow strict guidelines and you have the right documentation.

When it comes to home improvements, everyone wants to know the best tricks and tips. Should you go DIY? Which rooms should you focus on first? How do you find the best contractors?

Here’s what they said…

Know what adds value

While homes are first and foremost a place to live, they’re also an investment. It can be easy to see the costs involved with big improvement projects (like adding an extension) and feel a little nervous about the numbers. However, a lot of projects can pay off in the long run and you can often work with an architect to find out which improvements might give you the best return for investment.

One of the biggest factors in home value is location, location, location. The national average for value added by a 15m2 rear extension is around £40,000. However, that same extension in Central London can add anywhere between £124,000 - £280,000 in extra value!
