What Does an Interior Designer Do?
An interior designer plans, specifies, and coordinates everything inside a home — space planning and floor plans, lighting layouts, material and finish selection, custom millwork and cabinetry, furniture procurement, and on-site coordination with builders and trades from first drawings through final installation. A decorator furnishes a finished room; a designer shapes how the room is planned, built, lit, and finished. A professional interior designer guides a home from discovery and space planning through design development, documentation, construction coordination, procurement, installation, and styling, with detailed material management throughout.

More Than Decoration
The role of an interior designer is frequently misunderstood. Many homeowners assume it begins and ends with selecting colors, fabrics, and furniture. In reality, a skilled interior designer functions as a spatial strategist, project coordinator, material expert, and aesthetic translator — someone who transforms architectural potential into lived experience.

An interior designer plans, specifies, and coordinates everything inside a home — space planning and floor plans, lighting layouts, material and finish selection, custom millwork and cabinetry, furniture procurement, and on-site coordination with builders and trades from first drawings through final installation.

What Is Interior Design?
Interior design is the professional practice of planning, specifying, and coordinating the interior environment of a building so that it functions well, meets code and safety requirements, and expresses a coherent aesthetic point of view. It covers spatial layout, circulation, lighting, materials, millwork, furnishings, and the sequencing of trades required to build it. Interior design is distinct from decoration: decoration addresses the surface layer of a finished room, while interior design addresses how the room is planned, built, lit, and finished in the first place.
What Is an Interior Designer?
An interior designer is a trained professional who plans, researches, coordinates, and manages the enhancement of interior spaces to achieve a healthier and more aesthetically pleasing environment. Unlike decorators, interior designers work with architecture — modifying spatial layouts, specifying structural materials, coordinating with builders and architects, and managing every detail from blueprint through final installation. In luxury residential practice, an interior designer serves as the creative authority responsible for transforming architectural potential into a cohesive, livable home.
The Role of an Interior Designer on a Project Team
On a residential project, the interior designer's role is to hold the interior vision across every discipline that touches it. That means translating how a family actually lives into a floor plan, issuing finish and fixture specifications the builder can price and install, reviewing shop drawings for cabinetry and millwork, coordinating lighting and electrical placement before rough-in, and resolving conflicts between architectural intent, structural reality, and budget. Where an architect owns the envelope and structure, the interior designer owns the experience inside it — and is accountable for the result being consistent from the entry hall to the last drawer pull.
