The most unusual house -- The Hobbit House -- on the market in Ulster County. Virtually new construction (owner has spent a couple of weekends there), it is a completely green construction, done with care and imagination. Highly energy efficient (radiant heat in winter, thermal cool in summer), this domed cottageis literally built into a hill -- from which are wonderful views of Mohonk and the Gunks. Terrific location near Stone Ridge and High Falls. Very special indeed:nothing else like it. Yum.
