A breezeway is an architectural feature similar to a hallway that allows the passage of a breeze between structures to accommodate high winds, allow aeration, or provide aesthetic design variation. Often a breezeway is a simple roof connecting two structures (such as a house and a garage); sometimes it can be much more like a tunnel with windows on either side. It may also refer to a hallway between two wings of a larger building–such as between a house and a garage–that lacks heating and cooling but allows sheltered passage.
