The Downtown Brooklyn skyline has been redefined by the cluster of high-rises that has sprouted in recent years. And while 11 Hoyt, a new condominium being built on the site of a Macy’s parking garage, will certainly be tall at 57 stories, its development team hopes its design will help it stand out from the crowd.

The building, on the corner of Hoyt and Livingston Streets, will have 481 residences, priced between $600,000 for studios to about $3.4 million for four-bedroom units. Already several stories high, it is expected to be finished in 2020. Sales, conducted by Corcoran Sunshine Marketing Group, began this month .

Designed by Jeanne Gang, the founding principal of Chicago-based Studio Gang Architects, 11 Hoyt has a scalloped exterior made of cast concrete that, from a distance, resembles small waves lapping in the sky. But the waved exterior isn’t just decorative, Ms. Gang said. The undulating facade also pulls the interior borders outward, providing a little extra space for residents in many units.

Ms. Gang, an architect and a MacArthur Fellow, said she got the idea for the interior nooks after noticing all the protruding bay windows in brownstone Brooklyn. The extra space can be used to house plants, books, ornaments, or be turned into window seats. The complex geometry of these contemporary oriel windows and the resulting lack of right angles create about 190 different floor plans in the building.
