By the time Rose Zefferino was 25, she was managing over $60 million in residential construction projects. Not assisting. Not coordinating. Managing budgets, schedules, trades, clients, and the thousand decisions that determine whether a build comes together or falls apart.

That background is what separates Rose from virtually every other designer in the market. Most designers learn to work alongside builders. Rose learned to think like one. She knows what a late finish selection costs a builder. She knows how decisions made in week two affect what's possible in week twelve. And she knows that the gap between a beautiful design and a beautiful, buildable design is exactly where projects go wrong.

Rose leverages her two decades of experience with each client. She spent a decade in construction, from design through production, all before founding Z. Domus Designs a decade ago. She has earned a reputation across the region as someone who could navigate both worlds with equal fluency: the precision and discipline of construction, and the vision and craft of design. Builders trusted her. Clients loved working with her. That combination became the foundation of the firm.

Rose has a Bachelor’s degree in Applied Economics from Cornell University and a Masters in Construction Management from NYU.  She is also a licensed real estate agent in addition to her design credentials, which gives her a practical understanding of how design choices affect market value, knowledge that directly benefits her builder clients and any homeowner thinking about long-term investment, not just immediate aesthetics.

Outside the studio, Rose is most at home with family and friends, searching for the right coffee table book, traveling in search of remarkable beaches — often dragging her husband along to enjoy the fruits of their hard work — and spoiling her dog Alfie. Her husband jokes that they fell in love over strategic plans for their businesses, which might be more true than either of them wants to admit. If you know Rose, you know that she has a standing Wednesday night dinner with her five best friends, every single week. Her friendships are very important to her and help keep her grounded, despite all of the press coverage and acclaim she has received from Architectural Digest, Forbes and Home & Garden. Rose is also an active member of the Pennsylvania Homebuilders Association and ASID, not as a formality, but because staying connected to both industries is part of how she stays sharp.

Rose built her team the way she approaches a design project: thoughtfully, specifically, and with a clear sense of what she was looking for. Every person on the Z. Domus team was chosen for their character as much as their skill, because this work requires people who are genuinely invested in the outcome, not just the process.

The team brings expertise across interior design, project management, construction coordination, sourcing, and client services. Together they run a firm that can handle the full scope of a complex project—from pre-construction planning through final installation—without losing the personal attention that makes the work feel tailored rather than templated.

When you work with Z. Domus, you work with the whole team. Rose leads every project, and her team executes with the same standards she holds herself to.
