Don’t do it.

It's hard to do it well. Most instances just don't look good.

What is bump up cabinets? Never heard that term before. Do you mean staggered heights? Staggered is dated.

It’s very hard to do staggered height in budget cabinets because they don’t offer increased depth cabinets. Staggered height cabinets MUST also use staggered depth cabinets to go with it, in order for the crown molding projection to not create problems or ugly returns. Yes, it’s also not done very frequently these days. Because it’s harder and more expensive than most people think it “should” be. And then ends up looking ugly. And people think that the bad design and ugly install is the standard, rather than just badly done.
