Answer
Jan's assertion is incorrect. The kitchen is located on the Southern side of the house, which, in South Africa, does not receive much sunlight. Thus, it is likely that the kitchen has limited exposure to sunlight.

Answer
The windows depicted do not accurately represent those in the kitchen and dining room because the drawing suggests that they are meant for a bathroom, as they do not align with the actual layout of the kitchen.

Answer
Jan's statement about the scale being NOT very accurate is valid. When photocopying the plan, the scale can change, thereby distorting the dimensions, making it unreliable for precise measurements.
