From the analysis of the building plan, it can be determined that there are a total of 10 windows. This is identified by counting all the window symbols depicted in both FIGURE A and FIGURE B.

Number 1 corresponds to the Balcony. This is indicated by its position and label within the drawing.

Number 2 is identified as the Shower. This can be seen from the typical symbol used for shower installations in building plans.

Number 6 represents the One way switch – double pole. This is denoted on the plan by the specific symbol used for this type of electrical switch.

Number 8 corresponds to the Wash tub, which is represented by the conventional symbol for wash tubs in architectural drawings.

Number 9 indicates the number 7, which likely denotes a particular feature such as a door or window in the building plan.

The number indicating the garage door is 7, which is explicitly marked in the layout.

The omitted dimension for number 11 is indicated as 110 mm, which signifies the specific measurement for that element in the building plan.

The material to be used for number 5 is Concrete, as it is shown in the specifications for the relevant components of the building.

Number 3 (Balcony) can be abbreviated as WC, and Number 4 (a specific item) is indicated as WB/WHB.

A two-way switch is designed to control the same light or electrical fixture from two different locations, allowing for increased convenience in managing lighting across rooms or areas.

An appropriate flooring option for the kitchen includes Tiles, Novilon, Concrete, or Laminated Timber floors, offering durability and ease of cleaning.

The individual responsible for checking the drawing is P Kriel, as per the notations included in the plan documentation.

One fault in the bathroom, as depicted in FIGURE A, could be the lack of electrical connections or proper door positioning, which may affect accessibility and functionality.

An alternative light source suitable for use during load shedding includes Rechargeable bulbs, Candles, or battery-powered lights, which allow for continued illumination during outages.

During revision 1, the drawing of the Staircase was modified to enhance accessibility, while in revision 2, the drawing of the light fittings was adjusted for better coverage in each room.

The architect prescribed Paving as the finish for the ramp, ensuring proper traction and durability.

The symbol for a damp-proof membrane typically consists of a triple horizontal line indicating the area where the membrane is applied.

The symbol representing finished wood is illustrated by a series of diagonal lines crossing each other, denoting the surface treatment.

The symbol for hardcore filling is depicted using a series of intersecting lines, representing the layered structure of filling material.

To validate that the total horizontal dimensions are consistent, we examine both the top and bottom totals. For the top, we calculate:

For the bottom:

This confirms that both totals equal 8,060 mm, thereby validating the dimension consistency.

To calculate the area of the floor plan, multiply the length by the width:

Thus, the final answer, rounded to two decimal places, is 48.76 m².
