Ethan’s Glen, a Hines townhome development completed in 1978 near the Energy Corridor, clusters its quad pods around the community’s 32 wooded acres off Memorial Dr., just west of Paul Revere Dr. The 288 units feature rough-sawn cedar siding, sloped cedar shingle roofs, and cross-property views from semi-sheltered decks and balconies on 2 levels. One of the updated larger units popped up on the market this week, with a $329,000 asking price.
