Early Garden Shears greenhouse designs were of wood and stone or brick, built on south facing walls, and heated. Due to a glass tax (window tax) very little glass was used at this time, but once this tax was removed in the 19th century, a whole range of glass houses appeared. Steel work replaced wood, and designs became more complicated. Examples of this are the buildings at Kew Gardens, the Palm House, and the Crystal Palace built in 1851.

Mass produced greenhouses appeared around 1950, made from wood, aluminium and steel. Later new ideas were developed, like the hoop or tunnel greenhouse, and the Geodesic dome. All manner of innovations have been made - automatic windows and watering systems, automatic shading, humidity and temperature control Large Garden Pots.
