Custom carpentry & interior remodeling in Westfield, NJ
Westfield's walkable downtown and well-maintained colonials attract homeowners who care how interiors land — trim lines, bath finishes, and built-ins that look intentional. ONYX delivers that level of craftsmanship through an owner-led Design–Finish process.
Carpentry & remodeling in Westfield, NJ
Westfield projects often center on primary baths, library-style built-ins, and living rooms that need storage without sacrificing the formal character of the house. We design to the room's proportions and build millwork that looks original to the architecture.
Many Westfield homes already have solid bones and decent prior updates. ONYX focuses on the next tier — matching profiles, cleaner transitions, and finish carpentry that photographs as well as it lives day to day.
Rhett Mattson leads Westfield work personally from Warren. You hire a craftsman, not a project manager who subcontracts the details that make colonial interiors feel complete.
