Which role works with the Senior Designer in developing the concept?

• A. Senior Designer
• B. Designer / Intermediate Designer
• C. Project Manager
• D. Design Assistant / Junior Designer

Answer: (B)

Concept development in interior design relies on collaboration between the lead thinker and a mid-level designer who can translate ideas into concrete plans. The Designer / Intermediate Designer fits this role because they have the experience to take the senior designer’s vision and develop it into workable design development drawings, layouts, material palettes, and options. They bridge creative direction with practical execution, ensuring solutions are coherent, feasible, and ready for documentation and implementation.

The Project Manager focuses on schedules, budgets, and coordination rather than creating and iterating design concepts. The Design Assistant / Junior Designer supports drafting, documentation, and support tasks, often under supervision, rather than leading the development of the concept alongside the Senior Designer.
