Property Layout Mystery

[Dave Ventura]

Hi BP,

I am rehabbing my bathroom in my house hack right now and after demoing the wall I realized the studs were pretty new so I am assuming they are not the original layout. Plus the work is pretty shoddy from the previous "handyman" owner.  I am trying to figure out how the property was laid out previously and if it was possibly a 4 bedroom at some point. I would never understand why someone would downsize but if you see below it is pretty odd. 

In the pics below the yellow highlighted walls are the ones that are considered newer and what I believe are not part of the original build.

My thoughts are that maybe there was a master bedroom at some point or a bigger bathroom. Looking to see what others think or if someone is familiar with layouts in the old manyunk row homes. I have only been in a few. Thanks!!

Style: row home
