Attics are great for storage, but oftentimes homeowners will look at all that empty space and wonder… what if I added a bedroom up there? If you’re looking for a way to add square footage without the hassle, cost, and complexity of expanding your your home’s footprint, adding an attic bedroom can be a great way to go.

And depending on where you live, you may also be making a decent financial investment in your home.
