Which phase finalizes all interior details, furniture, and space plans?

• A. Schematic design
• B. Programming
• C. Design development
• D. Contract documentation

Answer: (C)

The phase where interior details, furniture, and space plans are locked in is the design development stage. This is when the approved concept from earlier work is refined into precise, coordinated choices—finalizing layouts, dimensions, finishes, materials, and the specific furniture and millwork details. It creates a complete, implementable package that shows exactly how the space will look and function, ready to be documented for construction and procurement.

As a reference, programming identifies needs and constraints, schematic design develops the concept and overall layout, and contract documentation prepares the detailed construction drawings and specs.
