Full-service interior design or turn-key interior design means the interior design firm manages all the work involved in a renovation or decoration project on behalf of the client. Everything from the initial design, through to selecting the items for the space, engaging any trades, placing the orders, managing the logistics of deliveries, coordinating installations, managing the timeline and budget, and accessorizing and styling. The biggest benefits to full-service design is the time and money clients save getting through the project.
