From coast to coast, micro-apartments are all the rage these days. Right on the heels of announcing the winning design team for its first micro-apartment competition, the New York Observer reported that the New York City Department of Housing Preservation and Development (HPD) Commissioner Matthew Wambua told a crowd at the Citizens Housing Planning Council yesterday that the city is already scouting out two or three city-owned sites for its next micro-unit development. Once these locations are identified, the HPD said it will put out requests for proposals.
