For those looking to improve, and not move, extending your property as part of an internal (and often external) remodel can offer the additional space you need and create a more attractive home.
When it comes to building an extension, a contemporary addition to the rear or side of your home is a popular choice. These examples are sure to offer plenty of design ideas and inspiration to get you started.
