As of 2015, the general cost to add a sunroom to a residential home ranges between approximately $15,000 to more than $75,000 per sunroom. The exact cost depends on the location, square footage needed, construction costs and design features of the sunroom.
A sunroom is a glass-enclosed living area attached to a house that home dwellers can use as additional living space during mild weather. The sunroom, also called a conservatory or a solarium, is accessible from within the home. Adding a sunroom to the home requires a building permit from local authorities, which adds to construction costs. Other factors that affect the pricing of a sunroom addition include material costs such as the foundation, the footings, skylights and window shades.
