Do you not get really hot if you are cooking something on the hob with something in the oven?
No because the ovens are insulated.
Never really thought about it before but makes so much sense! would not go back to the “conventional” layout (oven on the floor, under hob) now!
We have another place that’s going to get a new kitchen as it’s still on the original one from 1979! It’s got a ‘chest level’ double oven which is OK but it’s a small kitchen and the tall oven housing makes it seem even smaller.
My feeling is that having an oven below the worktop is no different to having a cupboard under the worktop and you wouldn’t think twice about that.
