The design of a conservatory is very important. The easiest way to decide on a style is to first think about the size of the conservatory. If you are limited for width a Victorian design on a narrow conservatory takes away those vital few feet on the corners where you need them. May be an Edwardian is the conservatory design for you. The next consideration is the furniture layout and the amount that you are going to put in it. A couple of large settees or a dining table will soon take the floor space up and so the position of the doors exiting on to the garden is key. If you remember that doors create walkways, furniture size and door position becomes easy. Why not peg out your proposed conservatory size on the garden just to make sure that you are happy with the size.
