The size of your new UPVC Conservatory would usually be up to you and your architect to discuss, depending on what you would like to use it for and the dimensions of your house & garden. Most architects work to the “Golden Ratio” for aesthetically pleasing dimensions; 1:1.168.
During the process of planning designing your new conservatory, you should think about what you want to use the new space for. A small sunroom style conservatory that simply adds an extra area of light to an existing room may be sufficient for some people, while others, who want a larger space to entertain guests or to serve as an extra lounge or dining area will need more space to accommodate their furniture.
It can be useful to think about the existing rooms in your home when deciding how big you want your conservatory to be, similarly laying out a pattern in your garden where you want to put the conservatory can be very helpful in determining how your new space will fit into its surroundings.
