More custom made and designed conservatories are being built in the U.S. than in any other country. This is mainly due in part to the fact that U. S. home owners have the money and the climate is suitable for them.
According to the National Sunroom Association, construction of these home additions has increased 40% since the year 2000 and has become a 2.5 billion dollar annual industry. Prices for sunrooms and conservatories can range from $25,000. to almost $1 milllion.
