What Is Architectural Millwork?
Architectural millwork refers to custom-made wood elements that enhance a building’s interior or exterior aesthetics and structure. This includes trim, moldings, paneling, cabinetry, staircases, ceiling treatments, doors, and built-ins—crafted not just for function, but to add character, cohesion, and design integrity to a space.
At Costa Millworks, we go beyond fabrication. We offer design-build millwork solutions, collaborating directly with homeowners, builders, architects, and designers to create handcrafted elements that fit seamlessly into your architectural vision.
