How does a conservatory differ from a greenhouse?
A conservatory is a greenhouse used toornamentals and is also an extension to a sitting room. Obviously, direct communication with the home is desirable, so conservatories are almost invariably lean-to structures. A decorative floor, which can be quarry-tiled or laid with vinyl sheet or tiles on a flat surface, is an advantage. Plants should also be displayed artistically and in suitable planters. Hanging plants, the use of evergreens and foliage, and good planning for year-round colour, are important to effective conservatory management. What you can grow depends on how much light the conservatory receives. A northern aspect is not a disadvantage since a wide range of conservatory plants like cool, shady conditions.
What are the advantages of a lean-to greenhouse?
It is ideal as a conservatory or garden room when attached to a dwelling, especially if there is a communicating door or French window. It may also help to keep a home warm and eliminate draughts. Lean-to structures make excellent vineries and fruit houses if built along a sunny garden wall. A south-facing house also acts as an efficient solar greenhouse: a brick or masonry wall holds the sun’s warmth during the day and radiates it at night. Under these circumstances a lean-to greenhouse can be used for any warmth-loving plants, and is also, of course, more economical to hea artificially.
