@duck this reminds me of almost dying the 20 times i walked out the second story backdoor at your dads place. 😂🤣 Idk why but my brain couldn’t handle the physics of a house with a walk out basement 

 "Nah I never have issues with Jehovah's Witnesses or other proselytizers waking me up on Saturday mornings!"

"Gee how did you accomplish that?" 

 "I just tell people to use the side door..." 😜 

 I have a family member with a door that would look similar to this. It was installed with the plan to build a deck in the future.    

 That was my assumption about this setup.

Did that family member walk out and you didn't see them until next Fall?
