Open-concept layouts in historic Maryland homes

Structural reality first

Most historic homes have load-bearing interior walls. Removal is possible — engineered beams, structural posts, foundation reinforcement — but it's real engineering, not a weekend project.

For a typical Bethesda colonial: removing the wall between kitchen and family room runs $8,000–$18,000 for the structural work alone (engineering, beam, post, drywall finish). Plus the kitchen renovation around it.

When historic preservation rules apply

Annapolis Historic District, Roland Park (in Baltimore), Chevy Chase Village, and other designated historic zones have Historic Preservation Commissions (HPC) that review exterior changes.

Interior modifications generally do not require HPC review unless the wall is historically significant or the modification affects the exterior in a visible way.

Verify your home's status before designing. The county/city historic register is public.

Keeping period character while opening up

Preserve trim profiles. Match crown, base, and casing in the new openings to existing originals. A reproduction crown molding cut to match is invisible; a flat MDF crown reads modern and wrong.

Match floor patterns. Hardwood weave-in: where new opens to existing, weave in matching planks instead of adding a transition strip. Sand and refinish the entire affected floor.

Restore visible original elements. If the home has original built-ins, leaded windows, or period fireplaces, keep them. The contrast between modernized layout and preserved period detail is what makes historic remodels memorable.

New cabinetry should reference period details. Inset doors instead of overlay, period-appropriate hardware, painted finishes consistent with the home's original era.

When NOT to open up a historic home

If the wall is structurally critical and the engineering cost outweighs the value (e.g., a $50K beam in a $400K home creates poor ROI).

If opening would destroy a defining historic feature (original built-in, period archway, structural masonry).

If the home is small enough that the existing rooms work — a 1,800 sq ft Federal Hill rowhouse usually feels better with rooms than as one open box.
