A Boutique Firm with a Builder’s Backbone.
Cosima & Company was founded with one mission: to represent homeowners with elegance, intelligence, and confidence through the most chaotic phase of their lives, renovation.
With over 20 years of boots-on-the-ground construction experience, we’ve sat on both sides of the table. Today, we bring that insight to clients who want their vision protected, their home respected, and their timeline controlled.
What Sets Us Apart?
We don’t build. We advocate.
Our loyalty is to you, not the contractor. We protect your vision.
Quiet luxury, not loud oversight.
Our work happens behind the scenes, keeping the project smooth.We speak both languages.
Trades and design. Schedules and finishes. We translate so you don’t have to.
Nick Stefos, Founder
“I’ve been the guy swinging the hammer at 5am. I’ve also been the one negotiating with architects, smoothing client panic, and salvaging busted budgets. At this point, my value isn’t just in what I know. It’s in how calmly I can guide someone else through it.” - Nick Stefos
Nick Stefos is not just a construction consultant, he’s a translator between vision and reality. With over 20 years of experience in both hands-on building and executive-level construction management, he’s built more than homes. He’s built trust.
Starting out in the trades, Nick worked his way from jobsite labor to leading multimillion-dollar renovations across New York. He learned the language of engineers, designers, inspectors, and craftspeople, not from a boardroom, but from the field. That’s what makes his work different. It’s not theoretical. It’s lived.
“Construction is personal. People invite you into their homes, sometimes into their chaos, and trust you to protect what matters most. I never took that lightly.”
At Cosima & Company, Nick leads a boutique consultancy that focuses not on building, but on protecting the people who are. He works with homeowners, designers, and architects to make sure that high-end renovations happen efficiently, elegantly, and without compromise.
His specialty? Navigating complexity. Especially with:
Historic properties
Ambitious custom builds
Clients who expect excellence, but don’t want to micromanage
“Luxury construction isn’t about expensive materials. It’s about peace of mind. The feeling that your home and your sanity are in capable hands.”
Whether advising on a brownstone restoration in the city or a legacy estate in Nyack, Nick shows up with quiet precision, long-range thinking, and an eye for the unseen.
