Code specifies front door size etc. I basically supplied sketches to the draft person.
The frame will probably be heavy section aromatic cedar from that tree that the “Tree Fella” dropped. In front of the main door will be a screen door perhaps a little forward to provide room to remove shoes before entering the home.
The bagging in front does not look anything like the plans but heavy buttressing is in place and an arch door on the outside of the front doorway will also be added later. Some rebar burglar bar work too?
