It was a momentous year for Prospect Heights and its neighborhood-inside-a-neighborhood, Pacific Park. Six of the megaproject’s buildings are now in various phases of construction, with SHoP’s prefabricated rental tower at 461 Dean Street already welcoming residents. The housing lottery for 535 Carlton, a fully-affordable development within the megaproject, opened in July, and the market-rate apartments of 550 Vanderbilt continued their selling streak. For a project that’s been in the works since 2003, that’s no small deal. The buzzy neighborhood even got a little more so when Oscar-winning actress Lupita Nyong’o was spotted perusing apartments at 550 Vanderbilt back in August.
