Brownstone Renovation in New York City

MH Construction specializes in brownstone renovation across NYC. We understand the unique challenges of working with historic NYC brownstones — preserving original details while modernizing layouts and systems, navigating Landmarks Preservation Commission (LPC) requirements, and managing multi-floor renovations that can span months. From garden-level conversions in Bed-Stuy to full parlor floor restorations in Park Slope, we bring these iconic homes back to life.

What Makes Brownstone Renovation Different

Brownstones aren’t just old houses — they’re engineering from another era. Built between the 1840s and 1910s, these row houses feature load-bearing masonry walls, timber joists, plaster-and-lath interior walls, cast iron plumbing, and ornate details that modern construction doesn’t replicate. Renovating a brownstone requires understanding how these buildings work structurally, knowing what can be modified and what must be preserved, and having the craftsmanship to match 150-year-old details when needed.

Our Brownstone Renovation Services

  • Full gut renovations — multi-floor, top-to-bottom rebuilds while preserving the brownstone shell. New plumbing, electrical, HVAC, insulation, and finishes on every floor
  • Parlor floor restoration — the parlor floor is the showpiece of any brownstone. We restore original moldings, ceiling medallions, and pocket doors, or recreate period-appropriate details when originals are beyond repair. Open layout conversions are popular but require careful structural planning
  • Garden level conversions — transform the ground floor into a rental apartment, in-law suite, or open-plan family space. Includes separate entrance, kitchen, bathroom, and egress compliance
  • Facade restoration — brownstone patching and Dutchman repairs (cutting out damaged sections and inserting new stone), repointing mortar joints, stoop repair and reconstruction, railing restoration, and cornice work
  • Structural reinforcement — steel beam installation for wall removals, floor joist sistering or replacement, foundation waterproofing, and addressing settlement issues common in 100+ year old buildings
  • Period-appropriate details — crown molding, ceiling medallions, wainscoting, pocket doors, newel posts, and balustrades. We source from architectural salvage when possible and custom-mill when necessary
  • Modern systems in historic frames — running new plumbing, electrical, and HVAC through a brownstone without destroying character requires creative routing. We use mini-split systems (no ductwork needed), PEX plumbing (flexible enough to route through old walls), and strategic placement of electrical panels
  • Roof replacement and repair — flat roofs on brownstones need regular attention. We install TPO or EPDM membrane roofing, repair parapets, and address drainage issues

Landmarks Preservation Commission (LPC)

Many NYC brownstones sit within designated historic districts — Park Slope, Fort Greene, Clinton Hill, Bed-Stuy, Brooklyn Heights, Harlem, and the Upper West Side among others. If your brownstone is landmarked, any visible exterior modification requires LPC approval: facade work, window replacement, stoop modifications, railings, cornice repair, and even paint color. The application process involves submitting detailed drawings and specifications. We have experience working within LPC guidelines and can help navigate the approval process — or advise on what changes are likely to be approved before you invest in architectural drawings.
