The Story
The Vision Behind This Project
The Challenge
This whole-home addition project transformed the upper level of a Northern Virginia residence through a carefully engineered dormer extension — approximately 33 feet wide — that unlocked an entirely new footprint for the primary suite. MOSS handled every phase of the work, from demolishing the existing roofline and bathroom to framing new exterior walls, floor, and roof structure, then finishing the space from the studs out. New Hardie board shingle siding clads the exterior addition, and five new windows were positioned during the design phase to maximize natural light throughout the expanded upper level.

Master Bathroom At the heart of the new primary bathroom, the shower system is built around Kohler's Temp-Rite Valve (K-8304-K-NA) paired with a Kohler Master Shower two- and three-way Transfer Valve (K-728-K-NA) — a combination that delivers precise temperature control and flexible water routing between fixtures. Completing the tub/shower assembly, a Fleurco DRNSLIDE-X-ABS-22 clicker waste and overflow with ABS pipe brings the suite together in polished nickel, a finish that reads as quietly refined against the homeowner-curated wall and floor tile.
Main Living Areas Red oak hardwood flooring, carefully selected and matched to the home's existing wood floors, runs throughout the upper-level addition. The continuity of grain and tone between old and new is one of the project's most quietly impactful details — the kind of choice that makes an addition feel like it was always there.
