For all the skill involved with doing that, it's still a kludge.

A properly designed kitchen is a better idea. Look at all the wasted cabinet space in the corner.

I installed a cabinet in a basement kitchen that had big cast iron wastewater pipes in the back of the cabinet behind the drawer. I shortened the back of the drawer 4 inches.
Yeehaw!

Probably would have been easier to use that God given talent to measure and buy the right stove in the first place.

But it then blocks the other drawer!?

In all fairness it could be the case that he couldn't find an oven he wanted that fit in that space. When my parent's old fridge died they had a hard time finding a fridge small enough to fit in the space as apparently most newer refrigerators are gigantic. So they found a smaller one, but it's a cheap and noisy piece of shit, they finally got the kitchen remodeled last summer and can now fit something decent in there when they decide to dump this one.
Clever solution, even if it does make my brain hurt a bit.
If he keeps up with the weird angles and such however I'm afraid he'll soon be making sacrifices to Dagon on the center island.
