That floor plan is not exact. Done by someone who put it together with what they thought it was. On that plan they show a door just left of the dining room and a door into the livingroom on the south wall. There is no door on the living room south wall.
Go to posting #36 for a map from the Modbee. At #4-5 are the French doors off the kitchen. #11 is door from the north side of the living room out to the driveway. Then there is the main door that leads into the front just left of the dining room. That is 3 doors is all. Not to many.
The only thing I know wrong with the Modbee floor plan and position of things is they put the mops and bucket in the wrong place.
Well, I see a door on that wall in the exterior views of that wall. Just to the right of the window as you walk towards the front door. Picture
Since that room was a garage previously that would have been a side door entry. I see what you are saying though, the patio doors in the dining room show as a window in the Modesto Bee layout.
