I want the additional space to be open and bright. A conservatory is just one design type of the general class of sunrooms.
Conservatories are the most attractive and typically most ornate.
With many sides, they sometimes have a circular appearance. The roofs are usually pitched and made of glass or clear plastic with fancy detailing. Once used primarily on upscale houses, conservatories are becoming more commonplace. Although still somewhat pricey, they typically return almost their entire cost in increased resale value of your house. Although it is difficult to describe in words, the styling of a true English-type conservatory is unmistakable.
