• Doors: Arched lines show the swing of the doors.
• Windows: Rectangular openings are shown in the external walls.
• Bathrooms: Symbols for toilet, sink, and possibly a shower or bath are indicated.
• Internal partitions: Thinner lines delineate rooms.
• Room dimensions: Numerical values within rooms indicate their area in square meters.
• Overall dimensions: Numerical values along the edges of the plan indicate lengths and widths.

The cross-section shows foundations, floor levels, walls, roof structure, and ceiling heights.
