Lean-to conservatory - Sometimes called Mediterranean this is the simplest type of conservatory and is a good option if you're on a tight budget.
Victorian conservatory - A very popular conservatory style with a bay front, pitched roof and ornate roof ridge.
Edwardian or Georgian conservatory - Similar to a Victorian conservatory, these have a flat front and a rectangular shape.
Gable conservatory - Gable conservatories are characterised by their roof - it doesn't slope back to the centre but stays upright to give a feeling of height.
P-Shape conservatory - A mix of lean-to and Victorian or Edwardian styles to create a "P" shape. These are often fairly large and good for providing flexible extra living space.
Lanterns - A glass "lantern" roof added to a more solid roof structure is popular in orangeries and can create a feeling of space and luxury.
Tiled roof conservatory - This type of conservatory is a bit more like an extension. This is because they have a fully tiled roof, rather that a glass one.
