Principles of Building Planning MCQ with answer and solution

Concept

Minimum width requirement for habitable rooms

Formula

NONE

Step-by-step solution

1. Habitable rooms require minimum dimensions to ensure adequate space for furniture arrangement and movement. 2. Standard building planning codes prescribe a minimum room width of 2.5 m for any habitable room. 3. Therefore, the minimum width of a habitable room is 2.5 m. Answer: C

Explanation

A habitable room must have sufficient dimensions to accommodate standard furniture arrangements and ensure comfortable human movement. National building codes specify that the minimum width for any habitable space, such as a bedroom, should not be less than 2.5 meters. Thus, 2.5 m represents the standard prescribed minimum width.

Why the other options are wrong

A) 1.8 m is suitable only for narrow passages, corridors, or store rooms. B) 2.1 m is the minimum width for kitchens or bathrooms, not habitable rooms. D) 3.0 m is a comfortable dimension but exceeds the legally mandated minimum width of 2.5 m.

Shortcut

Minimum allowable width for any habitable room is 2.4 m to 2.5 m.

Common mistake

Choosing 2.1 m or 1.8 m, which are minimum widths for non-habitable spaces like kitchens or corridors.
