What is Stage 2 in the RIBA Plan of Work?

• A. Concept Design: Architectural Concept Plan
• B. Build & Inspect
• C. Spatial Coordination: engineers and architects coordinate to make layout work together
• D. Technical Design - detailed arch + eng design

Answer: (D)

Stage 2 centers on turning the client's brief into a clear design concept. At this stage the team develops the architectural concept plan, exploring the building’s form, massing, and the relationships between spaces, while checking that the idea fits site constraints, planning requirements, and the client’s needs. It’s about selecting a preferred concept and outlining the broad design approach that will be refined in Stage 3 (Developed Design) and then documented in Stage 4 (Technical Design). This stage is not about detailed construction drawings or on-site construction work; those come later.
