Exceptional Design Build Firms in Washington DC
Selecting the right partner for your home project in Washington DC is often the most important decision a homeowner makes. The city’s historic architecture, narrow lots, strict zoning, and complex regulatory pathways can make even straightforward renovations require expert guidance. That’s why more homeowners are turning to design build firms in Washington DC—firms that unite architecture, interior design, and construction under one integrated process.
At MC3 Group, we deliver exactly that. As a licensed architecture practice and a design + build firm, we offer a comprehensive approach that merges creativity, engineering precision, and hands-on construction management. With headquarters in McLean and projects spanning the DC metropolitan area, we bring a deep understanding of both the art and logistics behind building in the nation’s capital.
Founded by architect John McKenna and designer-builder Maya Chehab, our firm takes pride in elevating residential design through thoughtful planning and exceptional craftsmanship. When homeowners choose MC3 Group, they gain a unified team dedicated to bringing their vision to life with clarity, efficiency, and artistry.
The Value of Integrated Design Build in Washington DC
The design and build model is rising in popularity across the region for good reason: it simplifies an otherwise fragmented process. Washington DC is not an easy environment for design or construction—tight rowhouse footprints, historic preservation boards, and stringent permitting processes often make traditional, multi-contractor workflows slow and unpredictable.
A truly integrated design build firm solves these issues before they ever appear.
With MC3 Group, you gain:
- One cohesive team from concept through construction
- Streamlined communication between designers, architects, and builders
- Aligned budgeting that starts early and stays stable
- Expert navigation of DC approvals, including zoning and historic districts
- A unified vision carried from the first sketch to the final detail
This model is especially effective in Washington DC, where even minor architectural adjustments can ripple across structural, regulatory, or utility systems. By managing the entire workflow, we eliminate conflicts between design intent and on-site execution.
What Distinguishes MC3 Group From Other Design Build Firms in Washington DC
Many firms offer construction. Others offer design. But very few offer the depth of service that MC3 Group provides—a blend of licensed architectural practice, construction management, and design leadership.
Architectural Expertise at the Core
As a licensed architecture firm, our team produces detailed architectural drawings, schematic designs, site analyses, feasibility assessments, and full permit sets. This is a distinguishing capability among local design build firms in Washington DC, and it enables us to handle complex, detail-rich homes with confidence.
Interior Design Integrated From the Start
Rather than treat interior design as an afterthought, we weave material selections, spatial flow, lighting studies, and finishes into every stage of the architectural process.
Construction Leadership That Honors Design Intent
Because our designers and builders collaborate daily, construction outcomes are consistent with the original creative vision. We protect both aesthetics and performance.
White-Glove Client Experience
Our clients benefit from a guided, concierge-like process with transparent communication, organized timelines, and a single point of accountability.
Our Start-to-Finish Process
Every project begins with understanding your goals, preferences, and how you want your home to support your lifestyle. From there, the experience becomes a curated, highly coordinated progression.
1. Consultation + Concept
We gather insights, site information, and project goals, then develop conceptual layouts and initial design direction.
2. Architectural + Interior Design
Our licensed architects and interior designers craft detailed plans, material palettes, elevations, structural solutions, and 3D visualizations.
3. Budget Development
Because construction happens in-house, we produce reliable budgets early—grounded in real conditions, not estimates detached from construction realities.
4. Permitting + Approvals
MC3 Group handles zoning reviews, building permits, historic board submissions, and all required documentation with DC agencies.
5. Construction Implementation
Our construction team, guided by the design leadership, builds each space with precision, craftsmanship, and meticulous adherence to the design.
6. Final Delivery
We walk through each detail, ensuring every room meets the standards of luxury, durability, and beauty that define MC3 Group.
