Custom Home Additions That Work with the Natural Flow of Your Space
We approach each home addition as an architectural extension, not an afterthought. That means careful attention to interior flow, scale and massing, and exterior tie-in so that your added space feels intentional and cohesive with your existing home. We also approach every project with an understanding of D.C.’s unique architectural context, particularly in neighborhoods where historic preservation and lot coverage restrictions shape what’s possible.

Why Build a Home Addition?
Skip the Hassle of Moving
A well-executed home addition increases usable space while preserving what works. Rather than relocate, build around how you live and on the lot you already own.
Add Real Value to Your Home
An extra bedroom, a larger kitchen, or a dedicated workspace can raise your home’s value by 60–80%, depending on scope and finish. These projects aren’t just functional; they’re investments in both lifestyle and equity.
Additions with Purpose and Payoff
Space should be programmed around function and flexibility. Every detail, from window placement to ceiling height, supports how the room is intended to be used. Check out our recent projects to see the possibilities.

Basement Conversions
There’s hidden potential right under your feet. We convert unfinished basements into inviting living areas, guest suites, media rooms, or creative workspaces.
Our Design + Build Process
From Vision to Reality, Expertly Managed at Every Step
Custom home additions demand a coordinated design + build process. Working in phases, we translate early concepts into construction-ready documents while integrating your feedback throughout. Your designer remains your central point of contact, so you’ll receive technical insight, vendor coordination, and alignment of design intent with construction feasibility at every step.
