Bathroom

Playful wallpaper from Graham & Brown livens up the house’s otherwise staid powder room, which also contains a pint-size Ikea sink.

The Duravit tub in the master bathroom is another favorite spot for keeping warm; it offers a slender view out toward the trees.

The Arnolds’ bedroom and living area float over the hillside, the large windows allowing light to flood in from both sides. A bamboo-enclosed deck sits atop the house’s foundation.
