Are you are considering a house extension or maybe to raise your house and put in a new floor. Raising your home can allow you to increase the height of your basement ceiling or create a new full basement from a crawl space. These and other methods could be the most cost effective ways to double the square footage of your home.
Another great reason to consider raising your house instead of adding an extension is to keep your precious backyard space. With the size of typical residential lots in the city you have limited space to enjoy the outdoors. Raising your home keeps your current outdoor space intact.
