Yes the long crazy S hall is unfortunate, but with just under 500 square feet and needing a 3/4 bath, a stairwell and 3 bedrooms? You might be able to do it but all 3 bedrooms would be quite small. Maybe you could do 2 smaller bedrooms and one tiny room for bunk beds or an office. Of course that depends on being able to move that ]bathroom to put the hall on the side where the stairwell is. Houses are not usually made to just move blocks around like in minecraft... so it might be spendy. You probably can do it... just matters how much cash you want to throw at it and if it makes financial sense for no gain in square footage.

First post a to scale floor plan

A lot of money for less than ideal. Maybe kids share with a partial wall.......still........

all is SMALL. Get an architect on your sire, look into additions...: )

Really doesn't seem worth it

Before you spend money, find out if it's legal. For example, if you're on a septic sized for two bedrooms, you wouldn't be allowed to add a third. Or if you have sloped ceilings, you could run into inadequate square footage for bedrooms.

Not on septic so thays not a concern but i appreciate it!

Thank you for sharing your thoughts. its a lot to ask for a 500 sqft space but appreciate it

I have seen many thoughtful remodels over the years where the toilet was kept in the same location (to save money on plumbing) but was rotated for a better layout - for me a priority would be to eliminate that back hall and would push the bath against the wall — then i would likely explore dividing up one of the bedrooms using floating storage or draperies

The minimum width required for a bedroom is 7'. Doing math the bottom room is too small to split, and the top room being 181" is 15'-1", so you'd be at 7'-4" width with no way to get to the back room through the tub or have closets. And, in practical terms a minimum sized (not necessarily comfortable) room for a twin bed is 9'x10'. Then, you have windows to think about, circulation width, HVAC, etc.

You would have to state your expectations for relocating the bathroom, window relocation, loss of the "loft" area next to stair, whether you can move the stair, etc. just to get good ideas. And, if you want more eyes and people's time, you'd have to do better drawings. Many posters are self-taught in free drawing software like FloorPlanner or Sketchup, and that is well-received as it shows they are not a fly-by-night post and commenters putting a lot of time into it might be worthy.

Depending on your local code, ceiling height has to be 7' for the area to count. So if those built-ins are there because there are eaves across the house, the square footage under the eaves in the bedrooms doesn't count.

Can you post more of the house? Maybe there is another option to steal the space.
