Costco, the international bulk grocery chain known for its warehouse looks and difficult-to-beat deals, is hard at work on what could be considered its biggest new product launch in years: affordable housing....but a whopping 800 residential units, including 184 set aside specifically for low-income tenants.The redone site will not only encompass the store and 800 individual apartments, it will also include a fitness area, multi-use community space, multiple courtyards and landscaped paths, a rooftop pool, and other amenities like gardens. Oh, and lots of parking too, of course. CONTINUED AT THE LINK - Diagrams,etc
