The house I live in was built around 1910. The kitchen ceiling is around 9 foot high. There's a built in electric oven and hob and above the hob the ceiling is lower, around five-and-a-half foot, so there's only just over 2 feet between the hob and the ceiling above it. My last home, built in the 1930s, was similar.
I think it must be something to do with what kind of oven the houses had when they were first built. Does anyone know? Also, isn't it dangerous to have the ceiling so close to the hob - fire risk? In my current house the ceiling is paint and plaster but in my last house it was tiles but also had a wooden shelf just above the oven but to one side, so not directly above, so if something had caught fire on the hob the flames could have quickly reached the wood. I would have thought this was unsafe but British Gas did a safety check of the oven and didn't say anything.
