Custom carpentry & interior remodeling in Millburn, NJ
Millburn Township homeowners — including those outside the Short Hills name — want interiors that keep pace with Essex County expectations: clean millwork lines, updated baths, and storage that doesn't look temporary. ONYX delivers that through owner-operated Design–Finish work.
Carpentry & remodeling in Millburn, NJ
Millburn projects often sit next to high-caliber neighboring homes, so finish quality has to hold up. We focus on precise casing, custom vanities, and built-ins sized for the room — not catalog units forced into openings.
Family rooms, secondary baths, and mudrooms are frequent Millburn starting points. ONYX scopes each phase so you can renovate in priority order without restarting design every time.
Rhett Mattson leads Millburn and Short Hills work personally from Warren. Essex County clients get the same single-craftsman model Somerset and Union homeowners already use.
Millburn home styles
Millburn Township homes range from classic colonials to expanded family houses — strong candidates for built-ins, bath renovations, and trim that elevates everyday rooms.
