oh boy. this will take some thinking. there are a lot of good people here to do that!

how does your dad get around? is he ok with the steps to bathroom? what about if/when he isn't ?

He gets around just fine and has no problem walking to the bathroom, he is already doing it now.

I HAVE SEARCHED AND SEARCHED THE INTERNET LOOKING FOR PLANS AND MOST HAD ELABORATE BATHROOMS THAT i COULD NOT SCALE DOWN. I just want something simple to take a shower and get the heck out. Always rushing in the morning and never linger too much in the bathroom. I am going to try to search tonight and see if I can find something. I could not make it work for anything and I know you must be stumped also because I ALWAYS get good ideas here. Making a smal house work is a BIGGGGGGG job LOL

I had all this written out and then lost my connection.

But basically, I would rearrange the space you have as bedrooms and your added bath and closet IF you have space under the porch for plumbing.

I don't know why you have such a convoluted plan for your addition, but I would just add a single rectangular room to the back for your living/sewing space, with pull down beds or futons for the grands.

If you take out the window in your now living room, that room will be really dark. I'd rip out the fireplace and make part of that front room the entry so you have light in all your spaces.

But without knowing your particulars, it's hard to say.

for small bathroom, see the 4th photo on this site. It's got everything, but packed into a small space.

post a layout of the bathroom. where's the door to it? is there a window?

This is so confusing. First thing I would consider is your roof lines and how your addition can fit with them. It looks like the only good addition place is across the back and I believe your kitchen window looks out at that corner garden. Do not want to loose that.

I think you would be best off hiring some one to look at this to give you ideas on what can be done. Architect?? Designer??

This is a very small part of your plan to consider. That corner cabinet is a waste f space. Honest. I have had one just like what you are showing and it is almost impossible to get dishes in it. They just do not like this cabinet. I have a small gun cabinet at 24 inches wide and 6 foot tall and about one foot deep. It now holds my deer collection but I used it as a china cabinet for a few years and it was really useful . The wall space you show would handle a cabinet like this much better than corner cabinet.

LOL I know it sounds difficult and I too am confused that's why i am here. Basically all I am trying to do is add a master suite and an enclosed porch. The deck has a roof over it so that is why I was trying to make my enclosed porch there. Shades you are probably right about the corner cabinet. The wall space that I have for it is 3' on each side which is about 1' larger than the normal cabinet so I thought that would make a difference.... I am trying to find someplace to store my pots and dishes as I still don't have enough room in the kitchen without storing in the basement (a MAJOR pain). I store my plates in a between the studs shelf in my hallway but the proposed design takes that out. Maybe somehow I can incorporate a small pantry closet?
Marti your family room proposal is the area where I am planning on putting the porch, bath and closet, but I added more sf to add the bedroom. Can't do the master suite in the front. the room on the right side was actually a porch that has since been enclosed and it is on a slab.with zero clearance under it. That would have also been my choice.
Here is my bathroom sketch.

I tried to use sketchup but could not make heads or tails of it but in the process I thought of another layout

I would use the ? mark room for living room and your now living room dinning room with cabinets for needed kitchen storage. What you have marked dinning room as your sun porch.

You could use a large buffet or two on the new big dinning room. Good for extra pots and pans out of sight in lower cabinet.

I know this would be entering into your dinning room. We had a house that way one time in fact our house NOW enters into the dinning room. It is not a problem at all and does not feel weird. At either house.

Not sure if wall between room 2 and 4 is also logs. If not open up the door way. If it is log then it is fine as it is.
