A main-level addition over a walkout basement added about 1200 sq. ft. to the back of a home in nearby southern NH. With our standard Beamed Exterior Wall System throughout, one side is a great room, and the other is the master bedroom suite that abuts the new 225 sq. ft. Liner Screen Porch. All areas are under a cathedral Beamed Roof System except the walk-in closets. The walkout level is currently designed for storage and utilities.
