Two additional bedrooms are filled with light and comfort, each enjoying access to a beautifully appointed bath-one en suite, the other just a few steps away. A whimsical "secret" bonus room adds charm and flexibility for imaginative play or clever storage.The lower level expands the living experience with impressive ceiling height, a bright media room, custom shelving, glass-enclosed home office, and a private guest suite with a spa-like bath.Outdoors, the magic continues.
