Victorian conservatories are also typified by an ornate roof ridge, though this roof ridge continued on into the Edwardian period. The main difference between the two styles is the bay front on the Victorian
Victorian conservatories can also come in 'P' shape where the conservatory has a lean to part making up the stem of the 'P' and a main area with a bay front protruding further from the main house.
