michele hernandez bayliss and daughter Alexia, 13, study the
nighttime sky in the rooftop observatory (facing page), where a
glass roof rolls back to reveal a 16½-inch Dobsonian telescope.
The site plan (facing page) shows the T-shaped property, which
is surrounded by protected state lands and is so steep that it
took more than a year to build a passable road. A bridge (above)
across a ravine and seasonal stream links the driveway and guest
parking to the front entry. Supported by steel beams and the
counterweight of the masonry chimney, 8 feet of the house is
cantilevered over the hill (left).
