I have an older 1960s house and the master layout is very similar in size and shape to this house's master suite (Pictures 13-15). You enter into the master bedroom, walk through the master bathroom, and into the closet area. No privacy doors! No ventilation in the bathroom![u] https://www.redfin.com/VA/Falls-Church/7415-Venice-St-22043/home/9478459

Thinking of reno possibilities. Would it make sense to keep the hallway but do a walk through closet on both sides? Closet on right side as well as closet on left side where the current standing shower is. Which would move the bathroom to the far end of the space where the green draped windows are. So instead of:
bedroom--> enclosed toilet --> shower/sink --> closets, it would be:
bedroom--> built in closets on either side --> enclosed bathroom including toilet, shower/tub, sink.

I like the idea of this so the bathroom can get good ventilation and sunlight. I'm thinking I could DIY the closet spaces with wardrobes and dressers, but would get a pro to do the bathroom reno. What do you think it might cost to shift the bathroom to the back of the space and convert the middle space into closets? Would moving the plumbing automatically be a huge cost such that it wouldn't be worth it? I could also just copy the layout seen in this house.
