Currently home to the Westpark Hotel, which will be demolished and eventually replaced, the Dittmar pitch calls for four new buildings configured around a central park — up to 1,300 residential units in two buildings, 150 to 300 hotel rooms in a third building, an amenity-only building constructed atop a 2,267-space parking garage and up to 24,500 square feet of retail overall. Arlington-based MTFA Architecture Inc. is the project architect.

The first phase will feature a single building, as tall as 31 stories, with between 480 and 610 residential units and up to 13,500 square feet of retail.
