Whether your door is left or right is all up to the owner’s preference or based on the property if there is any obstruction on one side or the other, or when opening space is limited by some other factor. Another factor that might affect the security door is whether it swings inwards or outwards. Typically, exterior doors open inwards, there are many reasons for this. The main reason is for security, the hinges for inward opening doors are inside which prevents any potential tampering and can also be more easily fitted with extra safety features. Another reason is for the convenience, inward opening makes it easier to open and shut the door without any interference. Weather can also affect outward opening doors, this means it would naturally experience a bit more wear and tear as a result.
