Solid walnut anything is a horrendous waste of a lot of good wood that could have been made into veneers. It’s also solidly in the luxury price realm of 160K and up cabinets.

I’m cur curious about the size and layout of your kitchen. Perhaps you could do flat fromt white cabinets with a walnut veneer island, or a walnut butcher block countetop, or just one set of walnut cabinets features somewhere in the room. You truly are going for one of the most expensive cabinets out there.

I get these pics are not your modern style but maybe they will inspire ideas for combining white with a feature moment of walnut.
