Beautiful spaces.
Personally designed.
At Black Wren Interiors, every room begins with a conversation. Led by designer Lauren Kosteski, we create custom spaces that feel deeply lived in, carefully edited, and endlessly comfortable. Whether it’s a fresh coat of paint, a refined furniture reset, or a full reno we bring order, beauty, and calm to the places you call home.
From brownstones to studios, every space needs a little love.
Lauren Kosteski brings a creative director’s eye to the world of interiors.
As the founder of Black Wren Studio, Lauren brings years of visual storytelling and strategic thinking to her interiors practice—but this is where she trades the big boardroom for the one in your home. Every project is collaborative, hands-on, and infused with Lauren’s signature blend of classic design sense, personal warmth, and eye for detail.
We partner with Brooklyn-based builders C.S. Scott to bring your vision to life—down to the last detail.
From custom millwork and paint precision to expertly executed installs, C.S. Scott brings craftsmanship, clarity, and calm to the build-out process. Together, we turn moodboards into tangible spaces, collaborating closely to ensure every design choice is not just beautiful, but buildable.
Let’s talk about your space.
