A lanai is a covered patio with open walls, while a Florida room has sides made of mesh screens or windows, with or without partial low walls. In addition, lanais often use concrete or other patio flooring, while Florida rooms may have more indoor-style flooring like tile or wood. Both allow you to enjoy the outdoors without being in the direct sun, but a lanai doesn’t offer any barrier against insects or debris.

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

There are many materials to choose from, including picket fencing, wood slats, galvanized metal skirting, dog-ear fence panels, scallop wood fence panels, bamboo screens, and other decorative screens. You can search for materials at local big box stores like Home Depot or scour online home improvement sites. Good search terms to use are fencing, skirting, and privacy panels.

In almost all cases, you will need permits if you plan on building a sunroom over your patio, but regulations and requirements will depend on your municipality. Permits to enclose your patio will usually cost between $300 and $1,000. Since navigating local building codes and zoning requirements is challenging—and the consequences of not following them can be extremely expensive—we strongly recommend hiring a sunroom builder to complete the work and pull the permits for you.
