- Edwardian conservatories typically have a pitched roof and are square or rectangular in shape with a flat front; they often have dwarf walls and are a popular choice as they blend well with different styles of homes.

- P-shaped conservatories are comprised of a rectangular section built against the property, leading to a square or rectangular section; similar to Edwardian or Victorian conservatory design.
- L-shaped conservatories can wrap around the side of the property, saving space in the garden.
- Victorian conservatories have a rounded look constructed by a number of facets at the front. The usually have bay windows, with a door placed off to the side. Traditionally Victorian conservatories have gothic shaped windows and doors and a curved roof structure.
