This summer Gerding Edlen Development opened a 51-unit apartment building in Portland, Oregon called The 20 on Hawthorne. The 20 is over 50% leased already and LEED Silver certification is pending. Homes range in price from $900-$2,500 and in size from 502 to 968 square feet. Perhaps more interestingly, though, this building has a stackable, automated parking system that fetches cars in about 30-40 seconds on average. It's pretty cool to watch.
