Installing a greenhouse window in a home is a popular way to nurture and display plants, as well as bring in more light and give the illusion of greater space in a room. Also called garden windows or box windows, they have aluminum or vinyl frames that are premanufactured to fit existing window sizes. Most feature a screened sloping top or side windows that can be opened for ventilation. A favorite location for greenhouse windows is in the kitchen, where it is convenient to grow and enjoy herbs and flowering plants throughout the year. The 1980s was the initial heyday for greenhouse windows, including the one seen here in Southern California, USA.
