Grade Architecture Files Permits and Reveals Interior Renderings for New 12-story Condo in Chelsea

Yesterday, permits were filed by architecture firm GRADE to build a 38,612 square-foot boutique condominium development at 117 West 21st Street in Chelsea. The Amirian Group is developing the site, and permits indicate it will rise 12 stories and host a bespoke 9-units. According to The Real Deal, which was first to report the permit filings, the residences will be called The Twenty1. The news aligns with GRADE's webpage for the project, which calls for a single townhouse unit, six full-floor homes on the 2nd through 9th floors, with two full-floor duplex penthouses above.
The GRADE webpage explains, "The interior design includes expansive, open floor plans and top-of-the-line materials, such as limestone, bronze, and wood, to create luxurious appeal." Its exterior will be a characterful composition of paired floor-to-ceiling glass panels that are deeply inset on frames of bronze-colored metal and stone. A vertical rung of wooden slats run up one side of the elevation, and its four penthouses progressively set back, yielding spacious terraces.

The new condominium will be constructed from the ground up, though it was originally set to rise from the structural bones of a four-story commercial building, which the developers bought for $28.5 million in 2015 according to Commercial Observer. Its surrounding neighborhood at the intersection of Flatiron and Chelsea has seen a sprinkling of high-end condominium developments over the past decade. Down the block, Alfa Development recently completed the environmentally-friendly Chelsea Green, where all sponsor units were quickly snapped up, with two returning active units priced at an average of $2,036 per square foot.
The existing commercial building was to be integrated into the new structure. It will now be demolished, and the condominium will be constructed from the ground up.
