Allegheny House Plan – From the Southern Living Design Collection. Charm and character can be found in this dream vacation home. Perfectly placed near a lake or high up in the mountains, the Allegheny offers it all when it comes to luxury holiday living. The first floor is customized for large family gatherings with its open-floor plan and double set of French doors leading to the vaulted, covered porch with its very own fireplace. To the left of the great room is the master suite, with its own private vaulted porch and a second guest room just across the hall. On the other side of the home, one will find the dining room and open kitchen looking onto a separate uncovered deck. Just downstairs, an oversized recreation area and separate game room can be found, perfect for board games on a rainy day or chilly night. A third bedroom and private bath are just down the hallway.
