As Skidmore, Owings & Merrill’s (SOM) iconic 270 Park Avenue, once lauded by Ada Louise Huxtable as one of New York’s contributions to a “dramatic revolution in architectural design,” prepares for a painstaking demolition process, new details have surfaced regarding its replacement. JPMorgan Chase announced in February 2018 that it would demolish the 707-foot structure to make way for a taller building on the site. The original building was completed in 1961 by SOM partner Natalie Griffin de Blois, the first woman to serve as lead architect in a midcentury corporate design project, and a key figure in the history of women in American architecture.

Since the announcement, details of the replacement have been scarce. Aside from the fact that Foster + Partners is leading design and Adamson Associates Architects is listed as the architect of record, little information has been released about the actual building. That is until an alleged tipster reached out to New York YIMBY earlier this week with images of the project model and 3D renderings of the final project. The images show the building with an asymmetrical setback design that gradually becomes narrower as it extends upward, topped with a parapet.

While New York YIMBY maintains that an anonymous tipster submitted the renderings, some industry professionals are skeptical. A side-by-side comparison shows that the new building was superimposed onto a previous rendering of Tower Fifth from earlier this year, and AN has not been able to confirm the authenticity of any of the images.

The original SOM structure is currently surrounded by scaffolding and cranes as crews prepare for the demolition. A completion date for the new tower at 270 Park Avenue has not yet been announced.
