Grainline Build Studio is a Brooklyn-based construction and millwork studio specializing in contemporary renovations, custom cabinetry and millwork in design-driven residential spaces.

As a millwork and construction company, we bridge the gap between design and execution. Custom cabinetry, architectural details, and structural renovation are not treated as separate trades — they are integrated from the start. We prioritize clarity before construction begins. That means clearly defined scope, detailed budgeting, and a realistic schedule. Once on site, our work is deliberate, clean, and systematic. Precision matters to us. So does durability. The materials we select, the tolerances we build to, and the way components come together are all considered long before installation day.

We aren’t volume builders. We take on projects we can execute at a high level — and we see them through with care.

We work best with homeowners, architects, and designers who value thoughtful construction and lasting materials. Our clients are investing in long-term spaces. They understand that craftsmanship requires planning, collaboration, and attention to detail. Whether it’s a full residential renovation or a custom millwork package, we partner closely with the project team to ensure design intent is preserved through fabrication and installation.

If you’re looking for work that feels intentional and built to last, we’d be glad to talk.
