Building Home Additions and Home Remodeling

Besides providing a home with more living space, home additions can be a terrific investment. House remodeling or a home addition, room addition or garage addition is less expensive than purchasing a new house. While this might seem like a "no-brainer," it needs to be mentioned. It is typically cheaper to build an addition or sunroom, add a room addition or garage addition than to buy a new home that equals the space of your existing house plus home addition. At the very least, the closing costs involved with selling your old house and buying the new house would push this option over the top.
