This structure, designed for attachment to an existing building, provides an enclosed space characterized by substantial glazing for maximizing solar gain. Such a structure typically comprises a frame, often constructed from materials like aluminum or wood, and transparent or translucent panels, commonly made of glass or polycarbonate. The design allows natural light and heat to penetrate, creating an environment suitable for plant cultivation, relaxation, or extending living space. The defining characteristic is its dependence on an existing structure for support and enclosure on at least one side.
The advantages of this type of construction include cost-effectiveness compared to freestanding structures, efficient use of available space, and the potential for passive solar heating. Historically, similar structures have been used for agricultural purposes, extending growing seasons and protecting plants from adverse weather conditions. The attachment to an existing building also facilitates easy access to utilities such as electricity and water, streamlining its integration into the home or business.
