Yes. But a backsplit is a house of staggered levels.
Level #1 (Top level) - 3 bedrooms and a bath. Equivalent to the second storey of a traditional home.
Down 8 steps, as opposed to 13 or 14 to Level #2 - living room, dining room, kitchen, front door. This level is 8 risers above grade. That's why you see so many steps leading to my front porch/front door in my pics.
Down 5 steps to Level #3 - side entry, hallway, bath, huge family room with patio doors to deck. This level is 2 risers above grade, is the exact same size as the bedroom level, and sits directly beneath the top level.
Down 8 steps to Level #4 (first basement level) - rec room, kitchenette, bedroom, laundry/bath. This level sits directly below the kitchen/living room level, and is only about half below grade
Down 4 steps to Level #5 (the basement, completely below grade) - two storage areas, a second rec room, utility room (furnace, water heater), huge walk in closet. This level sits directly below the family room, and has slightly lower headroom.
Levels 1,3, and 5 face north.
Levels 2 and 4 face south.
Levels 1 and 2 roofs are separate, and each has its own attic area and separate access hatches. You cannot access one attic from the other.
In short; yes five storeys, but each is smaller than in a traditional 3-level 2-storey. Yes, four sets of stairs, but only half flights. Split levels, due to their configuration, are difficult to cool.
And thus ends my most boring ever post.
@donaldtoo could probably explain it using American terms, in half as many words.
I've noticed Canadian bungalows and ranches mean something completely different than in the U.S.
