The architect refines the drawings of the building during the _______ design phase.

During the design process of a building, the refinement of drawings primarily occurs during the development phase. This phase is critical because it involves taking the initial visions and concepts and providing more detailed and technical drawings that will serve as a guide for construction.

In the context of the design phases, during the conceptual phase, broad ideas are explored without detailed specifics. The schematic phase focuses on establishing the general layout and spatial relationships, but it is during the development phase that the architect fine-tunes and elaborates on these ideas, addressing aspects like materials, construction methods, and other specifications critical for realizing the design.

The development phase encapsulates the transition from abstract to concrete, making it essential for ensuring that the drawings are ready for implementation and comply with all applicable codes and regulations.
