OUR STUDIO

“Design should reflect who you are - Not what’s trending.”

Founded by Nancy Rosett, Kostel Design began with a simple but radical mission: to disrupt the beige, risk-averse interiors that saturate the market. With a European-inspired, fashion-forward approach, we blend art, style, and spatial storytelling to craft spaces that feel unapologetically you.

We’re your creative co-conspirators—part designer, part stylist, part mood-setter. We turn up the volume on your personality and style so your home becomes a curated expression, not a catalog copy.

Our work celebrates individuality and style. We color outside the lines, but our process is refined and intentional — from concept to execution. We don’t follow trends; we set the mood.

From concept to completion, our team leads every phase of the design journey. We translate inspiration into reality through detailed layouts, material selections, FF&E schedules, design concept boards, renderings, furniture plans, and complete construction documentation.
Our studio thrives at the intersection of design and construction. We collaborate closely with architects, builders, and artisans to ensure each detail — from framing to finishes — aligns with the design vision.
We believe the best design outcomes are built on open communication and meticulous planning. Detailed budgets, schedules, and weekly site meetings keep every project running smoothly and transparently.
Perfect for hosts and creative entrepreneurs: we create memorable, statement-making spaces that photograph beautifully and stay booked.
