The site is on the west of Woodville Road, at the end of a 1,000 foot long private driveway. The house was originally built in 1975, using passive solar features & a wide variety of salvaged materials, including posts & beams from a 1800's mill building. Low indoor comfort, due to poor shell insulation & high air infiltration, led to the current renovation. The house is open from 10am to 4pm.
