Lisa and Mic O'Brien bought their 1930s home for one reason--it's located in one of the top school districts in the state. After renovating nearly every inch of the house, the hodgepodge basement stands out like a sore thumb with its crumbling walls, asbestos tile and drafty fireplace. They use the space every day for exercising and as a playroom for their son. Amy is going to help this couple turn the space into a home gym that's on par with the rest of the house. A rubber floor that looks like slate, custom cabinets, new windows, recessed lights, fresh walls, a mix of marble subway tile for the fireplace surround and gas fireplace insert, two TVs and some new exercise equipment will turn the space into a dreamy home gym that will make these homeowners rush to their workouts.
