The definition of astrology is the study of how the position and path of the sun, moon, and stars have a bearing on our lives. A horoscope based on where celestial bodies were on the day you were born is an example of astrology.
The overall cost depends on the type of your patio enclosure. For example, as of May 2011, a screened-in porch costs $500 to $15,000, while a four-season, custom-built sunroom with glass windows and temperature control costs upwards of $70,000, according to website Cost Helper. Prefabricated enclosed patios cost $10,000 to $30,000.
As you can see there is a tremendous amount of information that is compiled to make up a bid for a patio. A typical 400 sq ft patio (w/o accessories) as illustrated in the first example can range anywhere between $5,000 - $8,500 depending on all that is involved. A safe budget number for a patio similar to the one shown in example #2 can range between $40,000 - $50,000 again depending on the circumstances. Now, that is a pretty big number. A lot of multi-leveled patios typically range from $10,000 - $15,000 for a basic bi-level and up from there. All accessories range in price as well, but the list below is a good starting point.
