Why wasn't a small bifold door and perhaps a pocket door used in this design?

As one enters the "apartment" on the right I would have put a small single 24 inch bi-fold door for space to access coats, and incorporate a small area which could contain a two drawer unit for socks, etc.. and short length hanging rod for hanging the coats and daily clothing, then some shelving space for other things which are foldable clothing.

I would have then put a pocket door in the "kitchen" area so that I would have a very shallow pantry with multi level shelving for staples, canned goods and perhaps also it would provide space for paper products i.e. napkins, towel, and trash bags, plastic wrap, etc.

I grew up in a one bedroom home as a child which was shared with my mother, grandmother and sister. Mom slept on a fold out couch and my sister and I had bunk beds across from gram's twin bed. Total living space was perhaps less than 400 sq. feet. and it really wasn't all that bad.

I currently have a 1250 sq ft home w/ full finished basement on 6 rural acres (2 of which are wooded) and I can't even imagine living in a home any bigger than this. It's HUGE compared to my humble beginnings.

Guess growing up in such small spaces is why I have relocated doors, rebuilt closet spaces and removed other non essential things in my current home and optimized the spaces I do have. Looks very small from the outside and everyone that enters is shocked at how well laid out and big it looks once you step over the threshhold.
