The Differences Between a Three Season Rooms, Sunrooms, and Screened Porches…

Are you dreaming of adding a room to your home that will bring the outdoors inside? What types of activities will you enjoy in your new addition? How much of the year would you like to use it? Screened-in porches, 3-season rooms, and sunrooms (also called 4-season rooms) are extremely popular room additions. They all offer access to the great outdoors while also providing protection from the hot sun and pesky insects. Beyond that, each type has different benefits. Which type of room is best for you? We can help you decide. Let’s begin by sharing basic differences between these outdoor living options, with advantages and possibilities for each.

Three Season Room

Three-season rooms take the outdoor protection a step up, often featuring a finished vaulted ceiling, even cedar lined walls, and plenty of windows to allow fresh air in. Usually, the three-season room does not include heating or cooling. You could have a separate electric heater to take the chill off. This room does not have year-round options. The late spring, summer, and early fall the three-season room is wonderful for family enjoyment and entertainment of friends.


Sunrooms and 4-Season Rooms are two names for the same structure. This type of outdoor living space allows you to enjoy the outdoor scenery year-round in a bright and airy room that has all the comforts of the rest of your home. In reality, a sunroom is an interior room addition that is designed with a focus on the outdoors. Compared to screened porches and 3-season rooms, sunrooms are a more complicated home renovation project that involves HVAC systems, insulation, and abundant electricity options. This also means that you have a bit more freedom when designing, so you can integrate hardwood flooring, skylights, and even a fireplace. A sunroom addition acts as a bright lounge area that feels although you are outside when in reality you are in a temperature-regulated room.

Screened porch

A screened-in porch is an outdoor space that is adjacent to your home, covered by a roof, and enclosed by screens. The roof offers protection from the harsh glare of a hot summer sun, the downpour of a spring shower, or the cascade of falling autumn leaves. The screens allow you to enjoy fresh breezes while keeping out unwanted pests and insects. A screened porch is the simplest option, since it is basically a roof and screened walls over a deck or patio. it is not a year-round option. It is more of an extension of your backyard that features some comfortable furniture for lounging or entertaining during the warmer months of the year.

Now that you understand what exactly the difference is. Having one added to your home, may cause you to wonder “How much does each cost?”. The answer is, it depends. The cost of your addition depends on what your intended use is, the amount of time you intend to spend in your addition, and how you use it will dictate the size. Size, in construction, is a prime indicator of the cost to add an addition to your home. So are the quality of materials you select and the level of craftsmanship you employ. So calling in a professional to give you a bid would be a wise thing to do.
