MKCA works seamlessly across Architecture, Interior Design, and Product Design to deliver projects that are well-considered, cohesive, and connect people, materials, and place in ways that matter.

Before design begins, we help clients ask the right questions. Whether they are considering building a new home or building, evaluating a property, or preparing for a major renovation, our advisory services bring expertise and insight to the early stages of a project. We work with clients to define their goals, assess potential sites or existing buildings, develop a realistic scope and budget, and align their priorities and values with what’s achievable. Our goal is to ensure that when a project begins, it proceeds with purpose, intelligence, and clarity.

MKCA works on new buildings and renovations across the United States and internationally. We bring thoughtful design, technical expertise, and close collaboration to every stage of the process. Our work includes new houses in the Hudson Valley and throughout the United States, from Hawaii to Telluride, to Washington D.C., renovations and additions to landmarked brownstones and townhouses in Manhattan and Brooklyn, cooperative and condominium apartment and loft renovations throughout New York City, and renovations of historic buildings in Paris and the South of France.

Whether designing a ground-up home or new building, or reimagining a historic structure, our approach is innovative, collaborative, and deeply client-focused. We specialize in design that is thoughtful and detail-oriented – carefully considered, well crafted, and sensitive to place, climate, and the people who inhabit it. 

We are among the few architectural practices that offer full-service interior design and decoration. We provide interior design services as part of comprehensive projects integrating architectural and interior design services, or as a standalone service for clients who do not require extensive renovation or new construction.

Our interiors are tailored, expressive, and enduring, designed to reflect the distinct values and sensibilities of the people who live with them. Drawing on knowledge of historic design and contemporary independent makers, we combine custom furnishings, commissioned works, and carefully sourced vintage elements to create spaces with richness and depth.

Whether integrated with architecture from concept through completion or as a focused furnishing strategy, our interior design enhances spatial planning, enriches material palettes, and resolves challenges beyond architecture alone. This seamless integration allows us to create environments that are visually coherent and deeply attuned to how our clients live, balancing aesthetics, functionality, and investment with clarity, optimism, and thoughtful ease.

We are a hands-on practice committed to translating the values and aspirations of our clients into thoughtful and lasting outcomes. Working in close collaboration with contractors, craftspeople, and fabricators, we bring projects of many scales to life with equal attention to creativity, technical rigor, and integrity. Our role is not only to conceive design ideas but to ensure they are realized with care and clarity. Every project is guided by attentiveness to budgets, schedules, and professionalism, resulting in work that is both distinctive and responsive to the realities of building.

We believe design is a connector, a means of linking people, materials, and ideas, and of creating spaces that resonate with meaning. Our work is driven by a curiosity for how things are made and by a dedication to sourcing responsibly, whether through sustainable building components, inventive craft, or efficient methods of construction that tread lightly on the planet. At its core, our practice is guided by the belief that design should enrich daily life, balance innovation with integrity, and create experiences that inspire and endure.
