There is no easy way to make that house an open floorplan. If that is an important criteria, then it is the wrong house.

"My family has to move very quickly"

I would be very careful in rushing into a major purchase, specially one that you don't love and would require major money and time to turn it into something it isn't.

Agree this is not an easy home to just open. I would keep looking. Also if aging parents are moving in where are they going? I don’t see any rooms on this floor.

I cut the bedrooms out because they don’t play in. This house has 4 bedrooms and a extra family room all downstairs which makes it work for us. I would love to take more time but with a parent that needs to move in and can’t handle the stairs to get to a shower/bedroom the realities dictate what they must.

I didn’t know a way either but was hopeful someone knew something I didn’t. My only thought is trying to flips the stairs so they go along the left wall and open up that space. Then maybe turning the family room into a dining room, extend the kitchen that way and open it up to the existing dining room. But that will obviously be a major project to consider.

If you parent can’t handle stairs and maybe has mobility issues you also want to look at how big doorways are, if they could move about safely with a walker or wheelchair etc

Your intent is good......maybe not so much the process?

"I would love to take more time but with a parent that needs to move in and can’t handle the stairs to get to a shower/bedroom the realities dictate what they must."

Therefore...........

You will abandon a home you love, to take in a parent whose age we have no clue. You will also attempt a remodel in the space, with a parent needing help to some degree we don't know , and how many kids in the family - none some more?

What does YOUR home look like? You can't put a chair lift on your stair ? Would a small addition to your home make sense? A petite ADU?

There is no ground floor patio home, apartment, one floor ANYTHING rental for a year, for this parent whose issue is something beyond the stair or not? There is no near assisted living, even for an interim period until you sort everything out, or find something for all of you that doesn't require major rehab to make you happy? A reno that needs a plan, permits, and a budget which is what? 100K? 300K?

Your floor plan doesn't even show all the windows.

The only reasonable idea is to access the dining room, add to the kitchen, and turn the living room to "dining" or some other needed space. Stair move? More complicated and we are seeing one living floor, of a home that "ticks all the boxes" but actually doesn't do that : )

I think you're on rush, when perhaps there are different solutions. No matter what, we are not seeing the entire home, not seeing the interior, don't know a single thing beyond a parent can not manage a stair.

Taking in a parent is a big enough decision - a home purchase and remodel just more complication added to that.. None of those issues are really OUR business, but having cared for two aging parents? I'd just say this is r.u.s.h. at double time warp speed, and a lot fewer $$$$$$$ may yield better solutions for you the parent and your family.

Everyspace plays in and honestly an aging parent neededing care and a renovation are not a good combo .If you do not show us the bedrooms we have no clue and if they are all upstairs or own the the DR you show will now become abedroom but if the parent is using a walker or whelchair that is were you spend your mpnet right now since the bathroom is not ADA compliant at all Moving stairs is not a simple job it affects many things . My advice frind a short teem place to hosue your parent and either fix the home you are in or plan on 6 months min to even begin to fix this one

Over the years, we have made a bedroom out of the dining room, the TV room, the enclosed porch and the formal living room for four different aging family members. Perhaps your current home can be altered temporarily. Stair chairs are wonderful and way cheaper than moving. Living without the office or family room for a year or two may be the answer.

With the house you are showing us, the family room is already open to the kitchen, so it is not clear what you are needing.

The dining room would make a great suite and give the bathroom that is in the hallway to that suite by moving the toilet and adding a door directly from the suite and renovate to suit their needs. Leave everything else as is.

I would strongly recommend you slow down. You absolutely can host a family member in a temporary capacity while you look at upgrades to your home
Or to buying a new one tust actually meets your needs. Do not rush this. It won’t work well.

I've read the entire thread, (especially Owen's lone return comment) three times.

It rather makes no sense to say a home "ticks all the boxes" when it needs an overhaul to tick the very open living space, wish list.

It ticks a single box: a ground floor bedroom and bath, in a home where the bedrooms/baths not shown "don't play into" the conversation because it/they already exist in the "aged, broken up" floor plan of the home in consideration.

Without a ton of money, this house won't be the house left behind that "we love". It won't ever be that house.

On the if come a parent's condition worsens and caring for the parent becomes more complicated, the op is very likely to own the the home that suits nobody in particular.

No caring situation is identical. We know little beyond a need for a bed/bath.

If the issue is NOT one thing other than a stair climb, if the parent has possession of all faculties, can manage all the aspects of life to include driving to doctor appointments and activities, ( just needs a Handicap sticker ) making meals, managing finances, and is still otherwise vibrant?

Why would you not make the home of the parent, work for them? It needs a zero entry? A bed/bath carved out on the first floor?

Perhaps it JUST needs a zero entry and a stair chair lift? Who knows?

As to "care giving" in general, "aging in place", "forever" homes, getting carried out of a home feet first......and all the oft mentioned plans we routinely see here on this site?: )

God LAUGHS.. Or, in the words of my parents doctor? "After 80, physiology of the human body balances on the head of a pin"

I could not suffer that arrogant, albeit handsome, full of himself, pain in the ASS doctor...... but he was dead right.
