Additions are structural. Tie a new footprint into an old house wrong and you get cracked drywall, sloping floors, and a roofline that never sits right. This is the job where the difference between a real builder and a handyman with a truck shows up fast.
We manage all structural engineering, architectural tie-ins, and DC Department of Buildings permitting so your expansion is seamless.
Ground-floor square footage that flows with the existing home.
