The terms are used interchangeably in casual conversation, and the industry doesn’t always help clarify. But there is a real difference — one that matters when you’re deciding who to hire for your home.
What an Interior Decorator Does
An interior decorator works with the existing space: the walls, the floors, the architecture as it is. They select furniture, choose paint colors, style the room, and arrange what’s there. They may source pieces, manage procurement, and execute a particular look. They do not, typically, redesign the space itself. They are not trained in the technical aspects of space planning, building systems, or construction documentation.
What an Interior Designer Does
An interior designer does everything a decorator does, plus the work that comes before it: spatial analysis, floor plan development, lighting design, material specification, coordination with architects and contractors, and oversight of the construction process. A full-service interior designer can redesign how a space functions — not just how it looks. They understand building codes, construction sequencing, and trade coordination. They produce documentation that contractors can build from.
What a Full-Service Design Firm Does
At ARIID Group, we go further. We combine interior design with building design services — which means we can also handle the architectural work of reconfiguring spaces, adding rooms, or redesigning floor plans. We manage the construction process as well as the design. From concept through final styling and installation, the project stays under one roof.
Which One Do You Need?
If you’re painting, replacing furniture, and updating accessories without touching the structure or layout — a decorator may be sufficient. If you’re renovating, reconfiguring space, coordinating contractors, or need a cohesive design that holds together across multiple rooms and trades — you need an interior designer. If you also need the space itself to change structurally, or want one point of contact from design through completion — you need a full-service firm.
