Co-op & Condo Renovations
Renovating in New York requires more than just good taste–it demands a deep understanding of how the city works. We bring extensive experience navigating co-op and condo boards, helping clients avoid costly missteps and delays. Our firm has spent years working within New York City’s layered regulatory systems and design cultures. That knowledge allows us to guide projects efficiently, while staying true to our clients’ vision.

A well-designed workspace does more than look good–it functions beautifully. Our approach to commercial interiors blends thoughtful planning with design clarity, always tailored to the goals and culture of the organization. Whether we’re designing creative studios or executive offices, our team brings the expertise and sensitivity required to deliver compelling, performance-driven environments. We’ve developed a reputation among New York firms for creating interiors that support both collaboration and growth.

Great homes begin with a conversation. Our residential work is rooted in dialogue–with the site, with materials, and above all, with our clients. Mark Holmquist’s background in high-end residential architecture informs every project, from townhouses in Manhattan to houses outside the city.
