Distinguished DC Architecture Firms for Inspired Living
At MC3 Group, we believe architecture is not just about designing buildings — it’s about shaping experiences, lifestyles, and communities. As one of the most distinctive DC architecture firms, we bring a rare combination of licensed architectural expertise, interior design vision, and construction management under one roof. This integrated approach allows us to create homes that are at once elegant, functional, and enduring.
Founded by husband-and-wife team John McKenna and Maya Chehab, MC3 Group was established with the idea that the design + build process should be seamless, precise, and deeply personal. Unlike many DC architecture firms, we operate as both a licensed architecture practice and a design-build company. This dual role enables us to deliver projects that carry a consistent vision — from early schematic sketches to final construction details.
What Sets Us Apart from Other DC Architecture Firms
Washington, DC is home to many talented architects and builders, but few firms provide the comprehensive range of services that MC3 Group offers. Our strength lies in our holistic model, which eliminates gaps between design and construction.
Our architectural services include:
- Schematic and Conceptual Design
- Site Analysis and Feasibility Studies
- Permit Sets and Submissions
- Detailed Architectural Drawings
- Regulatory and Permit Navigation
Our construction services include:
- Custom Homes and Additions
- Interior and Exterior Remodeling
- Kitchens and Bathrooms
- Commercial, Pre-Sale, and Speculative Projects
- Construction Administration and Management
Finally, our design services bridge the gap between architecture and interiors, ensuring every space reflects a unified vision. From finishes to furnishings, we make certain the interiors complement the architectural intent.
Building in the Nation’s Capital
Each neighborhood in DC has its own architectural rhythm — historic rowhomes in Georgetown, stately colonials in Northwest, sleek modern builds along the waterfront. At MC3 Group, we tailor our designs to reflect both the uniqueness of the site and the individuality of the client.
As one of the premier DC architecture firms, we navigate the complexities of zoning requirements, preservation guidelines, and permitting processes. By managing these challenges with expertise and foresight, we free our clients to focus on the exciting parts of the journey — seeing their vision take shape.
A Legacy of Craft and Innovation
We pride ourselves on balancing timeless craftsmanship with forward-thinking design. Our work ranges from historically sensitive restorations to bold, contemporary residences. Whether expanding a traditional townhouse or designing a modern custom home, MC3 Group ensures every project is structurally sound, aesthetically refined, and tailored to the lives within it.
Our portfolio illustrates this philosophy — homes that feel rooted in their context yet elevated by thoughtful design choices and meticulous construction.
