We first heard about AvalonBay Communities' 24-story tower plan for the old McGuire Apartments site back in October. Tuesday, the developer and Ankrom Moisan Architects are presenting plans to the design review board with a much clearer look at what they have in store. Plans call for approximately 300 apartments, 10,000 square-feet of street-level commercial area and approximately 250 below-grade parking stalls, all dependent on the chosen concept. Their preferred concept makes the tower more slender as it rises and provides an amenity area on the podium as well as the rooftop. The resulting building would be an interlocking series of box designs that gives the structure texture and helps it from being too one-note.
