New Hall Archiyecture

In architecture, a hall is fundamentally a relatively large space enclosed by a roof and walls.  In the Iron Age, a mead hall was such a simple building and was the residence of a lord and his retainers. Later, rooms were partitioned from it, so that today the hall of a house is the space inside the front door through which the rooms are reached. In architecture, the head "double-loaded" describe corridors that connects to rooms on both sides. Conversely, a single-loaded corridor only has rooms on one side (and possible windows on the other). A blind corridor doesn't lead anywhere.  Source
