A Design-Build Approach Built for Clarity & Accountability

Rather than juggling separate architects, designers, and contractors, our clients work with a single, aligned group from start to finish.

As an in-house design build company, we manage architecture, interior design, permitting, and construction internally. This structure allows us to control quality, maintain realistic budgets, and ensure that what’s designed on paper is executed accurately in the field. The result is a smoother experience, fewer surprises, and better outcomes, especially on large or complex projects.

Design-Build Renovations for Homes That Need More

We specialize in projects where thoughtful planning and experience matter most. As a design-build firm for large renovations, our work often involves rethinking how a home functions—structurally, spatially, and aesthetically.

Below are the core project types we’re best known for:

Whole House & Full-Gut Renovations

Our whole house renovation projects often involve significant structural changes, layout reconfiguration, and full system upgrades. For homes that no longer meet a family’s needs, a full gut renovation in DC allows for a complete reset while preserving the character that makes the home special.

We design and build home additions to create more space without sacrificing flow or architectural integrity. Whether expanding vertically or horizontally, our team ensures additions feel intentional, not tacked on.

Kitchens are the heart of the home, and our kitchen remodeling projects reflect that. From highly functional layouts to refined detailing, our luxury kitchen renovations in DC balance everyday usability with timeless design.

Our bathroom remodeling services range from primary suite renovations to secondary and hall baths. Each space is designed to feel calm, durable, and tailored to how it’s actually used.

Our team regularly completes custom renovations in historic neighborhoods, where attention to detail and respect for original architecture are essential. We understand how to modernize a home thoughtfully, without erasing what makes it special.
