I’m pretty certain for building regs a garage space has to be lower than the inside rooms but not sure about a workshop
That is correct due to vapour leaks naturally from the car and that the vapour will lay low
and should not enter the home.
To stop vapour is to keep the fuel tank over half fuel to compress the vapour.
A big no no is putting a fridge or freezer in a working garage which I have seen a house explode due to
the Fire investigator found that the car had less than half a tank of fuel so more vapour is released and when the fridge motor kicked in to keep the fridge cool, then ignited the vapour and lost half of the house.
