Provided it is done correctly – ie that any necessary planning permission has been obtained and building regulations approved by your local authority – then an extension should increase the value of your home. If the work has been carried out professionally then it will definitely add thousands on to your home’s value. Recent research carried out by the Nationwide Building Society, for instance, showed that a bedroom extension with en-suite had the ability to add up to 23 per cent to the value of a property. A kitchen or bathroom extension added six per cent to the value. So, not only does an extension increase the value of your current home, it also makes living there much more comfortable and enjoyable!
