A Designer’s Curated Apartment Transformed By Vintage Charm

Washington, DC-based interior designer Molly Costello welcomes us inside her charming 700 sq ft apartment.

Faced with the challenge of softening the industrial design of her high-rise apartment, Molly has masterfully curated a space that feels both cozy and functional.

Through brass accents that reflect light beautifully, vintage finds, and Williamsburg-style antiques, she has created a striking contrast between old and new. Every piece in her home serves a purpose, with furniture being reimagined in unexpected ways—like a dry sink transformed into a stylish bar cart.

Molly’s love for recreating, reusing, and recycling is rooted in lessons from her childhood, shaping her design philosophy and influencing her work at MMC Interiors. She shares her expert tips for blending styles, maximizing function, and making a home feel truly personal—no matter the space.
