What does the 'H' symbol indicate on a floor plan?

1. Wall

2. Column

3. Door

4. Window

The correct answer is: Column

The 'H' symbol on a floor plan typically indicates a column. Columns are structural elements that support beams and the weight of the building above. The designation with an 'H' helps differentiate this symbol from others, ensuring that anyone reading the plan can easily identify where columns are located within the structure. In contrast, symbols for walls, doors, and windows have their own specific representations that differ from the 'H' designation. Walls are usually represented as thick lines, while doors take on a swing line pattern and windows are indicated by a break in the wall line or through the use of specific symbols. Understanding these markings is crucial for anyone involved in construction, design, or renovation, as they guide the physical interpretation of the architectural plan.
