Siding
This house uses standard vinyl siding. The siding is made from thin, flexible sheets of plastic about 2 millimeters thick, pre-colored and bent into shape during manufacturing. The sheets are 12 feet long and about a foot high. You start at the bottom and the sheets interlock into each other as you go up.

Because vinyl expands and contracts due to temperature and sunlight, it fits into deep channels at the corners and around windows and doors. The channels are deep enough that as the siding contracts it remains within the channel. The following shot shows a channel nailed to a corner of the house and a piece of siding fitting into it. It is nailed in place and ready for the next sheet to be interlocked and installed above it:
