How do you expand a home's square footage without expanding the home? It's easy: build an outdoor room, one of the biggest trends in home improvement. On DIY Network's Indoors Out, stonemasons and contractors Dean Marsico and Derek Stearns lead a crew of carpenters, landscapers and stonemasons to build unique, functional and eye-popping spaces outside the box. From outdoor TVs to spa showers to fully outfitted kitchens, Indoors Out makes great TV.
