We are guided by a layered approach that connects buildings, interiors, and objects into a cohesive and expressive whole. With over two decades of experience as a trusted residential architect in Manhattan, we specialize in high-end residential design throughout the city. Our work includes apartments, co-op and condominium renovations, townhouses, and custom-built homes. We also undertake select commercial, workplace, and cultural projects, bringing the same refined attention to detail to every assignment.

At the center of our work is ‘Design” itself -with a capital D. We believe design shapes not only how we build but also how we live. Our studio focuses not just on technical problem-solving but on creating spaces that uplift, endure, and resonate.

Mark Holmquist is a LEED-accredited architect and experienced interior design architect. He integrates sustainability and wellness into every project. This includes choosing long-lasting materials, energy-efficient systems, and spatial clarity that stands the test of time. Moreover, his work blends classical principles with modern rigor. He emphasizes proportion, restraint, and the tactile richness of architecture as an interior art.

For Holmquist, architecture provides a lasting framework. Interior and object design add layers of intimacy, adaptation, and meaning. True design is not about status or spectacle but about experience. Stillness. Grace. Joy.

Every project responds thoughtfully to its context. It is emotionally resonant, visually compelling, and deeply livable. From the Upper East Side to Lower Manhattan, Holmquist works as both a co-op designer and a residential architect that Manhattan homeowners rely on for apartment renovations. He creates spaces where clarity meets feeling and precision meets soul.
