Kitchen Additions and Bump-Outs in Bethesda When Your Kitchen Has Nowhere Left to Go

Kitchen additions in Bethesda, MD add floor area to the kitchen, either as a bump-out of a few feet or as a full addition off the back of the house. When no layout can fix a too-small kitchen, the only way is out, and zoning setbacks, permits and engineering decide how far.

How we work

How a Kitchen Addition Is Built

  1. Survey and zoning check
  2. Design and engineer drawings
  3. Permits (plus HAWP or town review where it applies)
  4. Foundation
  5. Framing and roof tie-in
  6. Opening the old exterior wall, often load-bearing
  7. Kitchen fit-out
  8. Inspections

Most families stay home and cook in a temporary kitchen while the old one is closed off.

How Long Does a Kitchen Addition Take?

Longer than the 10โ€“18 weeks of a full remodel, because of the foundation, framing and extra permits.

Can You Get More Kitchen Space Without an Addition?

Often yes: opening a wall, borrowing a pantry or mudroom, or a better layout can add usable space without building out. See open-concept kitchens and kitchen design.
