1. A hillside perch outside San Francisco: This home, The Hillside House, works with the site's natural topography and takes full advantage of its beautiful surroundings.
The most astonishing thing about this home is that one can bathe outdoors, up in the treetops.
Much of the square footage was dedicated to decks and open air spaces, but even the enclosed spaces are visually open to the beautiful surroundings. See the rest of this home
2. A family retreat on Cape Cod: A renovation of a midcentury modern home on Cape Cod included adding this incredible office space, which provides views through the scrubby pines to two kettle ponds.
Even on the first floor, the siting and open views make this large open space feel like a modern nest. See the rest of this home
3. A working farm in California: This home was designed for real farmers by their son. Their only demands were for simplicity and a water tower. The design of the tower was inspired by structures in the area.
A curving staircase up the tower incorporates the fun feel of a tree clubhouse's ladder.
4. A writer's studio in L.A.: Day or night, this is the perfect aerie for getting one's creative juices flowing.
This outbuilding on the edge of Griffith Park sits atop a hillside, creating an inspiring workspace for a Hollywood writer. It also serves as a guesthouse.
The deck provides a wonderful perch for grabbing some fresh air and being even closer to nature. See the rest of this home
5. An urban loft: A treehouse feel needn't be limited to a secluded forest or the suburbs. This loft in Atlanta ("the city in a forest") sits at the edge of a parkway and has great views of the downtown and midtown skylines.
The owner made the most of his small balcony, outfitting it with a comfortable daybed from West Elm. It has a table for two on the other side.
