Work is starting soon at the empty lot at 22-36 Caton Place, in Kensington. Hudson Companies, who developed Third + Bond in Gowanus, are behind the planned seven-story, 73-unit rental building. The DOB issued a new building permit this May and the contractor began mobilizing at the site this week. Construction is expected to last 18 months. The developers expect some action to start by the end of this week. Hudson Companies revealed their plans for the development at the beginning of the year. The building will feature parking for 50 percent of residents, a roof terrace with garden plots, a backyard, gym, and a part-time doorman. The development will be built to LEED standard.
