FAQs about Home Extensions

House extensions are popular especially in the ‘move or improve’ house climate we are currently in.  Sometimes opting for a smaller property in a desirable location that suits you makes more sense as you can always extend the footprint in the future when your situation allows.  To extend  your property brings many advantages such as a space where the whole family can spend time together, a lighter brighter home and it will undoubtedly add value to your property’s price.

The most common uses for house extensions are:


*Extending at the back of a property which usually houses the kitchen.  The extension allows this space to be turned into a bigger open plan area often with large doors out into the garden.  This option brings lots of light into the home and offers an area big enough for all the family to enjoy.


* Other reasons fro extending to be to gain an extra room such as utility room, bedrooms, playrooms, office or a home gym.

The current national average for an extension is around £1800 per sqm.  The cost depends entirely on your location and what finish you require
