Designed by NBBJ, the project, covering three of the city's downtown blocks currently occupied by parking lots, will be built in three phases of two to four years. According to Rosenstock, "The pieces-"Block 14″ to the south, "Block 19″ to the west, and "Block 20″ to the north- would each include a tower up to 37 stories tall surrounded by smaller buildings connected by skybridges. Phase one at Block 14 on Leonora Street will include a 1 million square-foot tower and a 40,000 square-foot meeting space and auditorium building."
Unveiled at a recent downtown design review committee meeting, "The most recent early design proposal focuses on plans for open space development on the site. Each will contain distinct landscaping, under the themes of "The Gallery," "The Park," and "The Garden." The first phase-the Gallery-will contain spaces for sculptures and other art; The Park will contain a larger field and an upper level dog area for the famously dog-friendly company; the last block will include a courtyard garden encircling the third tower."
