A recent Observer article describing designer Erin Fetherston‘s Tribeca loft uses adjectives like “dreamy,” “delicate,” and “airy,”  all of which also describe the ethereal apparel collections she has designed both under her own label and in collaboration with big names like Target and Cosabella. It’s fitting that this apartment, with its pale hues and spun-sugar decor, is located in Tribeca’s Sugar Warehouse condominium building at 79 Laight Street.

Ms. Fetherston has owned the unit since 2007, when she paid $4.33 million for the loft. She has been living with her husband and new baby in Los Angeles, so it’s up to another fashionable New Yorker to enjoy the 3,555-square-foot home, furnished with “rare antiques” and “stylish furniture,” including couches from ABC Home and Bergère-style chairs. The three-bedroom loft has graced the pages of Vogue (also featured here on the designer’s blog); it’s now seeking a new tenant, asking $22,995 a month.

It’s already a brag-worthy feat to own an apartment that was designed by an award-winning architect, but it’s even more brag-worthy to own one that was lovingly designed by that architect for her very own sister and her family. That’s why when we tell you that this 2,783-square-foot Tribeca pad in the landmarked Sugar Warehouse condominium is a gem, we mean it. The retro glam duplex loft was a collaboration between designer Stacey Ruhle Kliesch, her mother Louise Ruhle, and her sister, the homeowner, Stephanie Ruhle Hubbard. That’s right, even Mom was involved. So you know that every nook and cranny of this $5.2 million duplex loft was lovingly tended to.
