Interior Design and Architecture

Greg David Interiors is a full-service interior design and architecture studio specializing in refined, high-end residential spaces. Founded by Greg H. Witzman—both a trained architect and interior designer—the firm offers a seamless, start-to-finish approach that handles every aspect of your project under one roof: from permits and planning to construction oversight and finishing touches.

With degrees from NYU’s Institute of Fine Arts and a Master of Architecture from Pratt Institute, Greg’s work is deeply informed by his studies in New York and Florence, as well as years of experience at renowned firms like Peter Marino and Zeff Design. His projects have been featured in Interior Design Magazine, including Theory’s world headquarters and a 155-ft private yacht, Fathom.

At Greg David Interiors, design is never just about aesthetics—it’s about creating deeply personal spaces that reflect the way you live. Greg and his team take pride in managing every detail, allowing clients to focus on the vision while they handle the execution.

From concept to completion—interior design, architecture, and project management, all in one place.
