A deteriorating barn is transformed into a state-of-the-art home-entertainment space with original-looking beam work and warm, stained woods.

At first glance you would never expect that this 1,500-square-foot renovated barn, part of a 13-acre suburban Philadelphia estate in Bucks County, can convert into a high-tech home theater with the touch of a button. But do just that—press a single button on the Universal MX-850 remote—and concealed blackout shades descend from above, a projection screen drops down from behind a ceiling beam, the lights fade to black, and the projector jumps into action.
