That is a classic oak floor, I under no circumstances would ruin it with LVP over the top. As far as the slate no you cannot just lay something over the top. The LVP will not hold up and most likely you would break all the click locks.

I’m with millworkman and ABC. I know it’s no help to you, and you clearly state you hate them, but I vote for keeping those floors.

You’re so lucky to have those floors; work with them. Perhaps a consult with another flooring specialist or an interior designer will lead to a solution that allows you to use and appreciate these beautiful natural materials instead of plastic LVP that will only decrease the value of your home.

Plastic flooring traps moisture under it.... that moisture will warp the hardwood that telegraphs through the vinyl. Do you have a concrete sub-floor? DO NOT DO IT!!

Please just grin an bear your existing floors until you can afford the time and money to replace the slate with wood feathered in and then all sanded and stained to your liking. Really just patience is needed here.

Thanks for the input. I’ve been at a stall trying to design around these pieces and having trouble. To answer Q… this flooring is not on concrete subfloor- we are on a raised foundation on a slope. After more thought I think I will try to get a quote for laying similar wood in the kitchen and resurfacing if all to same color at some point. Seems expensive but probably around same cost as some of the engineered hardwood click locks and LVP I’ve seen… I guess I’ll find out. Anyone know what possible cost range would be? (I’m near Santa Cruz CA for reference)

Definitely have your local well vetted floor pro out to quote matching in the solid wood. The hardest part is demolishing the slate so you could save some money if you DIY that portion. But again, get some quotes from those that can see all your existing conditions.
