Apartments will be small, but not too small. According to one developer interviewed for the report, the ideal micro-apartment size is between 275 and 300 square feet. In the process of conducting consumer research, this unnamed developer had a grad student live in prototype units of different sizes, and found that that range was the optimum size for a "one person plus dog" household. It's the same size used by New York City's pilot micro-housing program, adAPT NYC. In other words, people are willing to deal with Murphy beds and hidden storage, but won't go as far to live with a motorhome-style combination bathroom/shower stall.
