Proposal for a churchyard.Pavilions may be small garden outbuildings, similar to a summer house or a kiosk; small rooms on the roof of a large house, reached only via the roof (rather than by internal stairs) may also be called pavilions. These were particularly popular up to the 18th century and can be equated to the Italian casina, formerly rendered in English casino. These often resembled small classical temples and follies. Especially if there is some space for food preparation, they may be called a banqueting house. A pavilion built to take advantage of a view may be referred to as a gazebo. Bandstands in a park are a class of pavilion. A poolhouse by a swimming pool may have sufficient character and charm to be called a pavilion. By contrast, a free-standing pavilion can also be a far larger building such as the Royal Pavilion at Brighton, which is in fact a large Indian-style palace; however, like its smaller namesakes, the common factor is that it was built for pleasure and relaxation.

A sports pavilion is usually a building adjacent to a sports ground used for changing clothes and often partaking of refreshments. Often it has a verandah to provide protection from the sun for spectators. In cricket grounds, as at Lord's, a cricket pavilion tends to be used for the building the players emerge from and return to, even when this is actually a large building including a grandstand. A pavilion in stadia, especially baseball parks, is a typically single-decked covered seating area (as opposed to the more expensive seating area of the main grandstand and the less expensive seating area of the uncovered bleachers).
