Floors, roofs, and partitions.

• FloorA room's walking surface, built from framing below and boards, blocks or strip flooring laid in deal, pitch pine, oak, birch or maple.
• RoofThe structure covering and closing the top of a building, its shape decided by the building's size, shape, location, use and looks.
• PartitionAn internal wall dividing a building into separate rooms, usually framed up in timber rather than built solid.
