A site spanning more than 10 acres that's sat undeveloped on Route 20 in Shrewsbury while a housing development has been planned there for years has sold for $2 million to a Boston development firm. The site at 440 Hartford Turnpike has been proposed as part of a 248-unit development known as The Pointe at Hills Farm in what's largely an industrial stretch of town. The project first went before town officials for permitting approval in 2015. Plans call for four three-story buildings to include 39 units each, centered around a small park and a 9,300-square-foot common clubhouse. A separate portion a few parcels to the north would include more buildings and green space in a second phase.
