How it works

The inside of a house in two drawings. The first takes the front wall off a two-story house so every room shows. The second is one wall of a room, for the finish names. British names are in brackets.

From the attic to the basement

The attic is the space under the roof, often used for storage. In this house the bedroom, its closet and the bathroom are upstairs, off the landing at the top of the stairs. On the ground floor the hallway leads from the front door to the living room, the dining room and the kitchen. The basement is below the ground; here it holds the laundry room. The garage, for the car, is built onto the side. On the wall, trim covers the joins: crown molding where the wall meets the ceiling, baseboard where it meets the floor, and casing round the door and the window.

British names: skirting board for baseboard, loft for attic, hall for hallway. An outlet is also called a socket.
A closet is built into the house. A wardrobe is a piece of furniture for hanging clothes.
