As far as "typical suburban" homes go, I can't really say that there are any. Are you talking about a moderately wealthy home, with say, two floors?

There are a couple of commonalities across the various homes I've been in, even though they may differ widely in layout:

-The main room off of the front door is usually large.
-Kitchens, side bedrooms, etc. generally have a direct line-of-sight into that initial main room.
-Depending on the purpose of the room, it may not have a door to secure it. Even if the most humble accomodations here in the U.S. most rooms have doors, so it can be odd to enter a room, and suddenly face several open and uncleared spaces. Think of the old MOUT training facilities before we got smart and realized that doors and furniture added to the realism of the training.
-There is usually a staircase that leads to the roof, or you'll find an exit on the second floor that leads to an exterior staircase, which in turn leads to the roof.
-The flooring is almost always slippery when wet, because there's no such thing as wall-to-wall carpeting except in the wealthiest of homes.
-The interiors can actually be very spartan by American standards, with few pieces of furniture.
