The life span of your solarium will depend on the materials used and how much wear and tear the room experiences from the inside and from the outside due to weather. On average, you can expect your solarium to last anywhere from 10 years to 50 or more. In rare cases, such as with old estates, solariums can last over 100 years.

A sunroom may count toward your home's total square footage or living space if it meets certain conditions, which can vary by local regulations. Generally, for a sunroom to be included, it must be fully enclosed, properly insulated, and equipped with electrical access and a heating and cooling (HVAC) system, similar to a four-season room. It should also meet the same construction standards as the rest of the house. Three-season sunrooms that function more like enclosed porches typically do not count toward the total square footage and are considered exterior living space.

The cost to build a sunroom averages around $47,000, but the price can range from $5,000 to $140,000 for high-end, custom projects. On a square-foot basis, you can expect to pay between $150 and $300. The total cost is influenced by the sunroom's type, size, materials, and other factors.
