A summerhouse is a type of building that is used for recreational purposes. It is usually found in gardens or parks and is often used as a place to relax and enjoy the outdoors. The term 'summerhouse' can refer to several different types of structures, including pavilions, gazebos, belvederes, and casinos. Pavilions are large, open-sided structures with a roof, typically used for outdoor events. Gazebos are similar to pavilions but are smaller and more enclosed. Belvederes are small, ornate buildings with a roof and open sides, often found in gardens. Casinos are buildings used for gambling and other entertainment activities. All of these structures can be considered summerhouses.
