What does the term 'blueprint' refer to in architectural terms?

In architectural terms, the term 'blueprint' refers to a detailed plan that provides comprehensive specifications and instructions for the construction of a building or structure. Blueprints typically include various aspects such as dimensions, materials, and procedures needed for construction. They serve as a critical tool for architects and builders, allowing them to visualize the final outcome and ensuring that all components of the design are meticulously considered and documented.

While a rough sketch might provide a general idea or concept, it lacks the precision and thoroughness found in a detailed plan. Similarly, a construction guide may be more procedural in nature, focusing on techniques and methods rather than on the complete architectural layout. Technical drawings can be part of a blueprint but may not encompass the entire plan or the structural details included in a detailed blueprint. Therefore, the choice indicating a detailed plan is the most accurate representation of the term 'blueprint' in an architectural context.
