The front door is the criteria of the house facing direction, not the big windows or the driveway.

※The importance of knowing your house facing direction?
The facing direction of your house is not necessarily the same as the facing direction of your main door. This issue lead to a great deal of confusion amongst practitioners, especially those wanting to benefit from the more advanced formulas of feng shui. It is beneficial and most important to know how to identify the facing direction of your house, and then to know how to take that direction correctly and with a good Compass Camera.
