A peasant is a pre-industrial agricultural laborer or a farmer with limited land-ownership, especially one living in the Middle Ages under feudalism and paying rent, tax, fees, or services to a landlord.[failed verification] In Europe, three classes of peasants existed: slave, serf, and free tenant. Peasants may hold title to land either in fee simple or by any of several forms of land tenure, among them socage, quit-rent, leasehold, and copyhold.

A house is a single-unit residential building, which may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers.
