It’s truly towering. And we’re not talking just height. We’re talking talent. Preeminent architecture and interiors firms, normally in competition with one another for commissions, have united for Waterline Square, the Upper West Side mega-project led by GID Development Group president James Linsley. Assigned to sites clustered in a parklike setting of 5 acres facing the Hudson River, Kohn Pedersen Fox Associates’s William Pedersen, Richard Meier & Partners Architects, and Rafael Vinoly Architects have each designed a glassy, angular building of 34 to 38 stories with condominiums at the top, rentals below. At ground level in the KPF building, Martin Brudnizki Design Studio will contribute a food hall. Connecting everything below ground is an amenities “club” orchestrated by Rockwell Group’s David Rockwell. As for the towers’ interiors, Champalimaud Design’s Alexandra Champalimaud is outfitting Richard Meier’s, Yabu Pushelberg’s George Yabu and Glenn Pushelberg are doing KPF’s, and Groves & Co.’s Russell Groves is paired with Rafael Vinoly. Dynamic duos, all.
