Great hallA great hall is the main room of a royal palace, castle or a large manor house or hall house in the Middle Ages, and continued to be built in the country houses of the 16th and early 17th centuries, although by then the family used the great chamber for eating and relaxing. At that time the word "great" simply meant big and had not acquired its modern connotations of excellence.
Manor houseA manor house was historically the main residence of the lord of the manor. The house formed the administrative centre of a manor in the European feudal system; within its great hall were usually held the lord's manorial courts, communal meals with manorial tenants and great banquets. The term is today loosely applied to various English country houses, mostly at the smaller end of the spectrum, sometimes dating from the Late Middle Ages, which currently or formerly house the landed gentry.
HouseA house is a single-unit residential building. It 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.
BuildingA building or edifice is an enclosed structure with a roof and walls, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons.
