Mark Holmquist is a New York–based architect whose work focuses on high-end residential renovations, including prewar co-ops and townhouses. His work is defined by the careful integration of architecture and interiors, resulting in spaces that are highly resolved, materially refined, and deeply responsive to their context.

His approach is informed by a broad foundation in the fine arts and interdisciplinary design, developed through his studies in the Design of the Environment at the University of Pennsylvania. Each project is conceived as a complete environment—shaped by light, history, and the specific character of the building—rather than the application of a predetermined style.

He studied at the University of Pennsylvania, earning both a Bachelor of Arts in the Design of the Environment and a Master of Architecture. He was awarded the Dale Fellowship to study in Rome, where he focused on historic urban form and the relationship between architecture and place.

Early in his career, Holmquist worked with architect Romaldo Giurgola on the U.S. Foreign Service Institute. He later led major public interior projects under AD100 designer Jamie Drake during the Bloomberg administration, including New York City Hall, the NYC Marriage Bureau, and Gracie Mansion.

Alongside his residential work, he has contributed to cultural and civic projects that require a high level of coordination, sensitivity, and design rigor. This experience continues to inform his approach, particularly in projects that demand both technical precision and an awareness of context and use.

His residential work includes projects in some of New York’s most distinguished buildings, including 720 Park Avenue, 770 Park Avenue, and The Dakota.

Holmquist leads a focused practice dedicated to delivering highly detailed, site-specific architecture in New York City. He works closely with clients to navigate the complexities of renovation while creating spaces that feel both considered and enduring.
