Hanok

A hanok's timber frame is built of posts and beams joined with mortise-and-tenon joints rather than iron nails, and carpenters shape the wood along its grain. The roof is laid with tiles of fired clay (giwa), whose curve gives the hanok its most striking outline; in the countryside roofs were also thatched. Korea has hot summers and cold winters, so a house must both let air through and keep warm: ondol carries heat from the kitchen fire under the floors, so in winter people sit and sleep on warm floors.

Find where the posts meet the beams and see how the timbers lock into each other; then look up at the curve of the eaves.
