Custom Millwork NYC
Residential, Commercial, and Custom Furniture Millwork Built in Long Island City
David G. Flatt provides custom millwork services for residential, commercial, retail, hospitality, office, and specialty furniture projects throughout New York City. From our Long Island City workshop, we design, fabricate, finish, and install made-to-measure millwork for clients who need precision, craftsmanship, and a finished result that fits the space.
Our work includes custom cabinetry, built-ins, wall units, reception desks, retail fixtures, bars, banquettes, architectural panels, custom tables, storage pieces, and specialty furniture. We collaborate with homeowners, interior designers, architects, general contractors, developers, retailers, and hospitality teams to bring detailed millwork projects from concept to completion.
A Full-Service NYC Millwork Shop
Custom millwork should feel intentional, built for the space, and made to last. At David G. Flatt, we approach each project with a practical understanding of design, materials, fabrication, finish, installation, and real-world use.
Because our team works across residential interiors, commercial spaces, trade show environments, retail displays, and fine furniture, we are comfortable solving both design and production challenges. We can work from architectural drawings, interior design concepts, shop drawings, or a rough idea that still needs development.
Our Long Island City shop allows us to keep production local, responsive, and hands-on. That local presence matters when a project requires site coordination, fast communication, custom finish samples, field measurements, or collaboration with a larger project team.
Residential Millwork
We create custom residential millwork for homes, apartments, townhouses, lofts, and private residences throughout NYC, Brooklyn, Queens, Long Island, and the surrounding area. Residential millwork is often where design, storage, and craftsmanship meet. The goal is not only to make a space look better, but to make it work better every day.
Our residential millwork services include:
Custom kitchen cabinets and pantries
Built-in wall units and media centers
Bathroom vanities
Mudroom and entryway storage
Walk-in closets and custom closet systems
Home offices and library shelving
Bars, niches, and specialty woodwork
Architectural paneling, trim, and molding
Custom furniture pieces for residential interiors
Each piece is made to fit the room, the design intent, and the way the space will be used. Whether the project calls for clean modern cabinetry, traditional detailing, painted built-ins, natural wood, veneer, laminate, or specialty finishes, we can help bring the design into production.







Commercial Millwork
Commercial millwork needs to look sharp, perform well, and fit within the schedule of a larger project. We fabricate custom commercial millwork for offices, retail stores, restaurants, showrooms, hospitality spaces, lobbies, and branded environments.
Our commercial millwork services include:
Reception desks and check-in counters
Retail fixtures and casework
Office kitchens, pantries, and storage
Hospitality bars, banquettes, and wall panels
Custom conference tables and millwork furniture
ADA-compliant cabinetry and built-ins
Front-of-house and back-of-house solutions
Architectural features, trim, and panels
Display fixtures and branded interior elements
We work with architects, interior designers, general contractors, construction managers, developers, property managers, retailers, restaurateurs, and office tenants. Our team understands the pace of commercial projects and the importance of communication, coordination, approvals, and dependable timelines.















Custom Furniture and Specialty Pieces
Some projects do not fit neatly into a cabinetry or built-in category. That is where our furniture background becomes especially useful. David G. Flatt began with a strong foundation in furniture and continues to build custom pieces for residential, commercial, retail, and hospitality clients.
We build:
Dining tables and coffee tables
Benches, banquettes, and daybeds
Custom desks and workstations
Sideboards, credenzas, and storage units
Display fixtures and retail furniture
Statement pieces and specialty builds
Seating with upholstery integration
Limited runs of custom fixtures or furniture pieces
Whether the project is a single custom table, a full set of retail display fixtures, or a specialty furniture piece designed for a specific interior, we can help refine the concept, choose materials, and fabricate the final piece with care.

Who We Work With
We regularly collaborate with both private clients and professional project teams. That includes homeowners, interior designers, architects, developers, general contractors, construction managers, retailers, hospitality groups, office tenants, and creative agencies.
Some clients come to us with a finished drawing set. Others need help developing an idea into something buildable. We are comfortable with both. Our role is to make the process clearer, help solve production details, and deliver millwork that matches the intent of the project.
Built for Designers, Contractors, and Property Owners
Every millwork project has its own set of priorities. Some projects begin with a detailed drawing set from an architect or designer. Others start with a problem that needs to be solved, such as adding storage, improving a retail display, upgrading a reception area, or creating a custom piece that cannot be purchased off the shelf.
David G. Flatt works with homeowners, designers, architects, contractors, retailers, hospitality teams, and commercial clients to turn those ideas into finished millwork. We can help review the project goals, discuss materials and finishes, coordinate fabrication details, and build pieces that are made specifically for the space.
Our goal is to make the process practical, clear, and well-executed from the first conversation through final installation.
