Is there a building How many windowsill windows are off the ground?
GB 50096-1999 4.2.1 provides that the railings height ≥1.05m. Floor windows and windowsill generally from the ground ≤ 300mm are considered landing windows.
Floor windows are not strictly speaking architectural terms, ah, this is a low window popular name. And the ground flush, but there will be an internal railing.
Floor windows are generally more than 20CM above the ground, how high is your distance from the ground? But too low is not safe ah, 900 most suitable, 100-300 are considered landing windows. Not well defined!
