This 1970s family room with a chunky rock fireplace and wood paneling is transformed with eco-friendly modern wall panels and a sleek stone and concrete fireplace that doubles as a bench. The adjoining living room is tied in as the wall between them becomes custom sliding pocket doors, with silver hardwood floors leading from one room to the next. A ceiling-mounted TV tops it off with a custom recycled aluminum entertainment center.

This boring game room was not cutting it for the man of the house. He wanted a place to watch sports with his buddies with the volume turned way up! To transform it into a proper home theater, the room is enclosed with a completely new soundproof wall. The popcorn ceiling is covered with a pattern of random-length lumber, and the tiny window is replaced with a door leading out to the backyard. A DIY television screen is "painted" on the main wall and surrounded with red laminate tiles for a punch of pizzazz. Finally, a cork floor is installed along with a window seat, which includes storage for various television components.
