Built with Ashlar Stone and brick including a slate roof and copper accents while lion motifs, quatrefoil windows and mature landscaping further accent the structures majestic exterior presence. The spectacular two-story Great Room is the architectural centerpiece, anchored by a massive stone fireplace and surrounded by intricate woodwork, soaring windows and carved Gothic trusses reclaimed from a 17th-century abbey. A musician's loft designed for a quartet overlooks the room, while a built-in koi pond and remarkable birdcages add layers of history and character. Beyond the 2nd floor Great Room, the first floor was designed to be lived in and includes an eat-in kitchen w/ pantry, half bath, laundry room, formal dining & family room w/ fireplace and garden access creating intimate spaces within the grandeur of the architecture.
