Home Additions
Space That Feels Original
The best home additions don't feel added on—they feel like they were always meant to be there. Our architect-led team designs and builds additions that seamlessly extend your home's character, improve flow, and create the extra space your lifestyle demands.
From primary suites to pop-tops and light-filled family rooms, we focus on additions that feel intentional, integrated, and tailored to how you live.

Why Additions Require Architectural Thinking
Adding onto a home is more complex than starting from scratch. Structure, rooflines, proportions, circulation, and light all need to work in harmony with what already exists. Our architects study your home carefully—inside and out—to design additions that feel integrated, not tacked on.
We consider how each new square foot changes the way you live: entries, views, connections to the yard, and the relationship between public and private spaces. The result is a home that feels cohesive, balanced, and significantly more livable.
Designed for Real Life
Tailored Additions for the Way You Live
Whether you're dreaming of a new primary suite, a larger family room, a sun-filled kitchen expansion, or a full second story, we design additions that feel purpose-built for your daily life.
- Primary Suite Additions: Quiet retreats with generous bedrooms, spa baths, and walk-in closets.
- Kitchen & Family Room Bump-Outs: Turn cramped rooms into open, light-filled hubs for everyday living and entertaining.
- Second-Story & Pop-Top Additions: Add square footage by building up instead of out, preserving outdoor space.
- Sunrooms & Porch Conversions: Capture natural light and connect more fully with your yard year-round.
Every addition is designed as part of a bigger picture, so your updated home feels unified in style, scale, and experience.
Seamless Integration
Seamless Inside & Out
Great additions respect what makes your home special. We align new rooflines, window proportions, materials, and details with the original architecture so the finished home reads as one coherent whole.
Inside, we rethink circulation, transitions, and sightlines so moving between old and new spaces feels effortless. Often, the most memorable design moments happen at these junctions—a framed view to the garden, an opened-up stair, or a widened hall that suddenly fills with light.
- Roof & façade alignment: New massing that respects scale, rhythm, and proportion.
- Material continuity: Brick, siding, trim, and windows selected to complement—or thoughtfully update—the existing exterior.
- Interior transitions: Openings, casework, and trim that knit old and new spaces together.
- Light & views: Window and door placement that enhances natural light and connections to the landscape.
Zoning & Approvals
Navigating Setbacks, Zoning, and Permits
Additions live at the intersection of design and regulation. Our team is experienced with local zoning codes, historic districts, and review boards across the DC, Maryland, and Virginia region.
We study lot coverage, height limits, setbacks, and easements early, so your design is both inspiring and buildable. Then we handle permitting and coordination to keep your project moving forward.
- Feasibility studies and zoning/code analysis.
- Site planning to maximize usable space within regulations.
- Permit drawings, submissions, and agency coordination.
Frequently Asked Questions
Common questions about home additions in the DC area.

How much does a home addition cost per square foot?
Costs vary widely based on complexity, finishes, and site conditions. We provide a detailed estimate after our initial consultation and design phase, rather than a generic square-foot price.
