50-100k as a starting point with architect’s fees, engineering, demo, new walls, new floors, and the specialist contractor to build the new staircase. Or 4 times that. In some markets you might get every penny of that back. In some you might get zero.

Thank you for your help. Would an architect be the first person to talk with to start this type of project? Or a contractor?

I had the same thought as chispa--eliminate the back stairs entirely. You'd probably need a structural engineer or architect to make sure that eliminating the stairs would not compromise the integrity of the house.

I don't see how removing the staircase gains you any useable space. Perhaps the sides of the staircase could be opened to allow more light to penetrate the area, but the space gained will only be for cirulation.

Are you sure your furnishings are arrange in the best fashion to take advantage of what the current layout provides?

The goal would be to somehow make it feel like a more open concept and expand the kitchen or add an island. Not sure if removing the stairs on one side would help to achieve this or not?

Thank you for your feedback!

Why not post pics of the area so we can see what you call out as a closed concept.?

Again if i just eliminate the staircase in the back the space your gain is not in the work pattern of the kitchen. Adding an island in that area doesn't make any sense for function.

If you want to remove the walls from either side of the staircase so that it looks more expansive and the light extends from the Family Room to the kitchen that might work.

I have no idea why 2 staircases at all so maybe explain the need . I think removing the back one makes sense but it will not have much effect on the kitchen size yo will still not have space for an island. I need info and some pics of your space and both staircases ther eis no way to get even basic help without pics.

The middle photo is the front stairs the other two are into the living room/kitchen

Eliminating the rear stairs doesn't give you any more room for furnishings, but it does provide better flow throughout the back of the house. You might even get more room upstairs for the bathroom or closet.

What are the "loft" rooms?

The upstairs flow is not great at all so more room in the loft area would be wonderful. I’ll send photos. Does it appear to be any way to add kitchen and or counter space in this house? Thanks again for all of your help!

You need to get a structural engineer and an architect to even begin to figure out what is doable , what it will cost and will it be a ton better? The kitchen in the plan does not look like the kitchen in the pics

There's a peninsula in the kitchen which is not shown on the plans--was that added?

Thank you for all of your help. Looking to make the whole house have a more modern feel . Are you aware of someone I could hire put together a rendering that would include new flooring, updated stairs, etc?

Removing the stairs doesn't give you any of your goals. It's just a 100K+ expense to remove a stair. With nothing in return. You need a different house entirely. Put this one up for sale and go find that modern house that you want. This one will not be it,

You need an on site professional (I e architect or interior designer that specializes in space planning) to work with you on this. All the changes you want aren’t internetable. Is this house worth investing 100s of thousands into?
