LOVE YOUR HOME & NEIGHBORHOOD — BUT NEED MORE SPACE?

Moving isn't always the answer.

For many Northern Virginia homeowners, a well-planned home addition can create the extra space they need while keeping the location and home they already love.

Maybe your family needs a larger kitchen and family room. Maybe you're considering a new primary suite, home office, guest space, garage, or second-floor expansion.

That's where careful planning matters.

A home addition needs to connect properly with the existing house — structurally, visually, and functionally. Zoning, setbacks, permits, engineering, utilities, rooflines, foundations, and interior flow can all affect what is possible.

THINKING ABOUT A HOME ADDITION?

Cosmo Builders provides home addition and expansion services throughout Northern Virginia, helping homeowners move from an initial idea toward a properly planned construction project.

Our team can help coordinate:

✓ Design & project planning
✓ Budget and scope development
✓ Architectural & engineering coordination
✓ Permit coordination
✓ Structural construction
✓ Electrical, plumbing & mechanical work
✓ Interior and exterior finishes
✓ Final inspections & project completion
