It’s a New York story: Boy meets girl meets loft apartment. “There’s no 'he said, she said,'” declares interior designer and architect-in-training Jennifer Vaughn about her relationship with fiancé Derrick Miller, who is creative director of the men's accessories label Barker Black and its Manhattan shop. “There’s only 'we said.'” It's a good thing, because their apartment’s small size (just over 500 square feet) and their shoestring budget to fix it up posed enough challenges. Both inherent classicists in their respective design sensibilities, the couple made the close quarters—a living area and nook of a kitchen topped by a miniscule sleeping loft—feel quite grand. But when your pad is this petite, function is tantamount. Vaughn credits her mentor and boss, Laura Bohn, with teaching her to design more livable spaces. At home, that meant mostly streamlined furniture and creative solutions for much-needed storage. Such efficiency doesn’t come at the expense of personality, though: There are choice moments of character (the beat-up club chair) and decadence (the fur pillows), and Vaughn and Miller have peppered the apartment with a well-edited array of keepsakes and decorative objects—most found on the cheap at the flea markets they comb together.
