Overview
More room, seamlessly yours
A well-designed addition should look like it was always part of your home. From bump-outs and sunrooms to full second stories, we match rooflines, siding, and interior detail so the new space flows naturally from the old.
As a design-build firm we carry your addition from architectural drawings through county permits to final walkthrough — one team, one contract, one point of accountability. Additions typically run 3–6 months depending on scope.

Cornerstone remodeled our kitchen and we could not be happier. The design team listened to how we actually cook and live, and the crew was meticulous and on schedule every single day.

From the first consult to the final walkthrough, everything was under one roof — one contract, one team. The daily portal updates made the whole build feel effortless.

★★★★★
They turned our unfinished basement into a guest suite and home gym. Tidy job site, respectful crew, and the finished space exceeded the 3D renderings.
How long does a typical remodel take?+
It depends on scope — most bathrooms run 4–6 weeks of construction, kitchens 6–10, basements 8–12, and additions 3–6 months. You'll get a detailed schedule before we break ground, with daily updates in your client portal.
Do you handle permits and inspections?+
Yes. As a full design-build firm we handle all drawings, permits, and county inspections across Howard, Carroll, Montgomery, and Frederick Counties.
Do we need to move out during the project?+
Rarely. We contain the work area with dust barriers and keep essential spaces functional — most families live comfortably at home through kitchen, bath, and basement remodels.
How does pricing work?+
After an in-home consultation we provide a detailed fixed proposal — design, materials, and construction in one contract. Our Investment Guide shares typical ranges before you even call.
Are you licensed and insured?+
Yes — MHIC 129673, fully insured, and award-winning since 2011, including Baltimore Sun's Best Remodeler 2026.
