The Raritan Inn (pictured at right), a 275-year old former Victorian, underwent a two-year renovation by Asdal Builders.  The Inn uses the most innovative renewable energy technologies - solar power and geothermal heating and cooling.  The Innkeeper's residence is a residential power plant that has set the standard for environmentally conscious restoration.
        The Raritan Inn has been featured in many articles, both for its extensive renovations and for its commitment to innovative "green" technologies and energy-saving measures.
