Floor Plan Symbols
Floor plan symbols are basically looking down from the top of the house. In-floor plans we found this type of symbols, it includes furniture, windows, doors, etc. Some common symbols of floor plans are compass, doors, stairs, windows, walls, applications.
- Compass: It is basically an arrow symbol that gives orientation to the building by which the architect or builder can easily understand the north direction. By this symbol, we can easily detect east, west, north, south directions.
- Doors: Door symbol is presented by the straight line and the arc shows the opening projection of the door.
- Stairs: It is basically drawn by parallel lines which is generally located between two windows.
- Windows: The symbol of window is basically denoted by three lines.
- Walls: Walls are generally two types; interior walls and exterior walls. Both walls are drawn by two parallel lines but exterior wall lines are dark, thick and interior wall lines are light.
- Appliances: These are basically the other symbols in floor plan which are bathtub, toilet, sinks, other furniture, etc. All appliances symbols are drawn by single lines.
Some floor plan abbreviations.
