over the North pole
To build a house with all walls facing south, you would need to choose a location near the North Pole, where south is the only direction available. However, this is impractical for habitation. In a more feasible scenario, you could design a house in a circular or dome shape with a central courtyard facing south, but this would not have traditional walls in the typical sense. Ultimately, constructing a house with walls entirely facing south is not possible in conventional geography.
A house with walls all facing in the same direction is a house that is sitting smack bang on top of the north pole. that way, all four walls are facing south. :D
If all directions are south, then the house stands on the north pole, and the bear is white.
This only happens in the northern hemisphere, and the reason is becasue South is the main direction of the sun. It will rise in the South-east and set in the South-west, but a house facing South will get sunlight all day.
This depends on the specific location and orientation of the house. In the northern hemisphere, the south-facing side typically receives the most sunlight throughout the day. In the southern hemisphere, the north-facing side tends to get the most sunlight.
Because of the tilt of the Sun in winter, the sun will strike the south facing windows facing windows for most of the day.
The only way this is possible is if the house is built directly on the North Pole.
If you are facing south, then east is to your left.
If you are facing south, then the east is to your left.
How much of an overhang needed depends on how big your property (and especially your south facing window) is. You'll need to get an expert on this matter to check out your house and then you'll know.
Temperature wise, in warm environments, the basement would be the coolest part of the house. Socially speaking, the coolest part of a house would be the game room or entertainment room.
