The obvious reason for house extensions? To add much-needed space onto the existing home. It could also be time for a complete remodel and while you’re at it, incorporate a house extension as part of it.
Just by adding a few square feet can make a world of difference. It can mean the difference of an extra bedroom or two. An additional office or den. Who couldn’t use an extra bathroom? A larger living room for entertaining?
There is no right or wrong reason for considering an extension to your home.
