A conservatory is an extension or room that is usually attached to one side of the house using glass roof and walls. It is known by other names including greenhouse, sun-room, and solarium, among others. By Britain standards, a structure is considered a conservatory if at least half of its side wall area is glazed and at least three-fourths of its roof is glazed with translucent materials such as glass or poly-carbonate sheeting.
The first known English conservatories were made during the 16th century. They were owned by rich landowners who started cultivating citrus fruits which only normally grew in warmer regions such as lemons and oranges. For places that have cold climates such as England to enjoy tropical plants and flowers, there is a need to provide for the right environment through conservatories. Conservatories eventually served other purposes such as venues for tea parties, breakfast areas or simply covered areas in gardens.
