The concept of "garden rooms" has been dated to the Romans, who included rooms within some homes that opened on one side onto a garden. The horticultural scholar and gardener Marie-Luise Gothein identified such a room at Pliny's Villa Tusci, in her study "A History of Garden Art". In the late 19th century, reaction set in against both the Victorian fashion for elaborate bedding and Italianate formality, and the earlier 18th century landscape gardening modelled on the paintings of Claude Lorrain and Nicolas Poussin. This led in part to a concept of the "garden room" (distinct from the architectural concept of a garden room) as a space out of doors, in which paths, corresponding to halls in a house, lead to enclosed gardens within the garden as a whole, conceived of as rooms. The architect Hermann Muthesius described the style which developed into the Arts and Crafts approach in his "" ("The English House"): "the garden is seen as a continuation of the rooms of the house, almost a series of ... outdoor rooms, each of which is self-contained". A number of pre-Sissinghurst gardeners, including Jekyll and Lawrence Johnston, had designed in this style, and much of their work was known to Sackville-West and Nicolson. This landscaping feature has since become an established one in garden design.
