[A contractor explained to me that split-level means you only have the "entrance landing" at street level, then go up half a flight of stairs to the chambers, and down half a flight of stairs to the living area. He said single-story offset means when you enter at street level and basically go straight into the chambers, and you go down a (full) flight of stairs to the living rooms/kitchen, etc.] Then I hope he builds better than he can explain. "Split Level" means "staggered floors," where not only the "entrance landing" is offset, but typically the house depth is halved and a two-flight straight staircase connects the two levels so that each connects to a landing; in weaker slopes, for example, the living area can be three steps lower than the dining area. So, for example, you have the entrance at street level "level 0" with a partial basement "-1" below, and behind it the garden level "-0.5" with the chambers on the floor "+0.5" above. An example of split level in the forum can be found at (by the way with, in my opinion, the coolest TV emperor’s lodge kitchen ever, basically the house for watching the World Cup, I’m still amazed after what I think is four years now – although the sauna is also really worth mentioning).
