A B shaped conservatory is one of the larger styles available, and has two large end sections which typically have shaped walls (hexagonal in style as opposed to a square end). The middle section is set in closer to the house than the ends. In this sense it is similar to the lean to style as it is attached to the rear of the property, and the two sections which help to form the B shape stretch out into the garden. As you stand and look at the rear of the property, the B shaped conservatory will have the appearance of being constructed in three separate portions.
If you are thinking of having a B shaped conservatory added to your property, you are really limited by the width of your house. Because of the angles involved in creating each section of the B - plus the insertion of the middle section - you need to have a wide house to be able to take full advantage of this shape. It also helps to have a big garden.
The sheer size of this style makes it an extremely versatile conservatory to have. You can use each section of the B for a completely different purpose if you wish; one section could be used as a play area for the children, while the other areas can be split between relaxing and perhaps eating dinner.
It also makes an ideal centre for entertaining purposes, as it vastly increases the overall size of the reception rooms you have available. In this sense you are able to use the B shaped conservatory as a room in which the whole family can get together; it's not too small to be used for just one activity at a time.
