We've seen the very good, the bad, and the ugly in barn conversions. This six-bedroom retreat in Pennsylvania's Bucks County seems to get it right. The 200 year-old barn was converted into an expansive 6,900 square-foot contemporary residence, boasting thoughtfully-placed original details with the requisite modern finishes. Asking $2,495,000, the house features a floor-to-ceiling fireplace in the living room, a massive outdoor deck overlooking Bowman's Tower Preserve, and a media room with expansive 10-foot viewing screen. Outside, there's a horse barn that, per the listing, "could become a guest house or pool house. The owner has some drawing ideas."
