From the heart to a quiet forest in Wilmington, Delaware, this contemporary tree house was admittedly a labor of love for architect Whitney Sander of Sander Architects. Built for her sister after the death of their father, this warm, wooden, wooded residence evokes the feeling of “home” surrounded by hundreds of hundred-year-old trees whose leaves join to create a leafy 150-ft. “ceiling.” With a rushing stream at its feet, Tree House features a spectacular spiral staircase, running up the front of the home, past the modern Juliet-inspired balcony, and the expanse of glass that forms the front facade. The home’s very vertical construction places the master bedroom and living at the top, among the trees, with a rooftop deck as the most luxurious crowning touch. Sander Architects.
