Way beyond the scope of this forum. You need a very good architect to start My first quetion is how many seats do you need for eating. To me the original would have been a tear down so porly designed and honestly the 2 you show not much better . I will start by saying bigger is not always better in home design

Agree an architect + kitchen designer is needed for a project like this

What attracted you to this home?

How big is the lot?

How close are the neighbors?

What are the views from the different spaces?

Where is the main outdoor entertaining area?

Not every question is one for Houzz.

You need an architect on site. Whatever you paid for the house, was less than a similar size home, .........few people really want an indoor pool, so you may have gotten a great "deal"

Use the dollars saved to make a home that suits. Not here. Architect in order: )

You need a TEAM

Architect

Interior Designer

PRO Kitchen and bath designer

Builder

All working in tandem with synergy, communication, all on the same page for look, style, intent . execution ...............that's the team.

@chispa

What attracted you to this home?

Privacy; large lot where many dont exist; very few neighbors

How big is the lot? .78 acres, 34,000 sq feet

How close are the neighbors?

only 1 neighbor on side of the indoor pool area.

What are the views from the different spaces?

The back of the house faces mountains; front of the house looks at greenspace

Where is the main outdoor entertaining area?

Main Outdoor space is off the back of the house; pool is position off the entrance; and BBQ\outdoor living is off the living room; but thats another challenge in itself.

For all those responding with needing a "team" we have a team, everyone has their input; but I've been driving the direction of layout; and we've done exploratory demo to find out what walls cant move and such.. We are working within the layout. Tearing it down and rebuilding it in this state would cost 2-3X more. There is alot of value in whats left over.

You have a team listen to them if they are actual pros and not your friends or relatives . I have no info as to why this size home ever unless you have more than one family living in it. IMO built to impress not actually for real life unless as I said . Any chance of help from here will require a ton of info oops I see the lot is 35000 sq ft what is the size of the house since it is almost impossible to read measurent s

^^^^^

That kitchen, alone.............shows why you need the "team" .........which seems not to include a PRO K,D

You do not know what ( how much )you don't know.

A house this size with those clearances? That would be HARD no.

Not a pro but I’d be tempted to remove the pantry and shift the kitchen that way to get some more access to natural light -

I would not do the second island and I would not put the range and sink opposite of each other - makes for a tight working space for no reason

There is not enough information presented on both existing or desired programming. The main approach to the house (what do you consider the front?) arrives past private outdoor living. A Motor Court is shown in one drawing, an attached garage in another. A fence or partial wall of another building is shown across from the indoor pool. The backyard and neighbor is unknown on proportions/distance. The thick walls on the existing drawing looks to be a masonry built house, on the proposed drawings it is now a wood framed house. The Family Room fireplace is a big part of the equation, can that even be removed. The outdoor cooking is unclear if that is just a wheeled BBQ on one of the collonaded porches.

Questioning the proposed programming, I quite like the indoor lap pool, it appears to be adding seamlessly to the level of house, and has adjacent spaces that functionally mate to it. The Gym space needed is not defined, but sounds like quite a bit and a big part of the remodel. The dining seats are unclear as to seating 8 at a dual-island with 10 in a formal Dining simultaneously. As far as opening up the Kitchen/Family Room to modern American ways of living, making a "roomed" house be open concept has to be done within the framework of the concept of a "roomed" house, otherwise it would be a muddled mess or you arrive at:

"but whatever we try; we feel like it doesnt work; or its off"

I don't know the team you have assembled, but the proposed plans don't appear to be successful, and that might be partially or wholly contributed to the programming set by you.

Without knowing anything other than what I can decipher from drawings, here is a scheme I might want to look at. I can't read dimensions, so room sizes are based on proportions of other rooms in the house, which they should be.
