Most sunroom or patio room additions are wonderful during the warmer months of the year. They add living space to your house, giving you more space to entertain, relax or whatever else suits your or your family’s needs. Once the winter comes, however, you shut the door to keep the cold out and avoid spending time there until the temperatures rise. If you want to make the room usable all year round, however, a four-season room is what you are looking for.

The difference between a three-season room and a four-season room comes down to how they are connected to the house.
There are two key systems from your home that are not connected to a three-season room: heating and air conditioning.
Not so for a four-season room.
Not only can you relax and watch the birds in your backyard with a cold lemonade or soda during the summer, but you can watch the snow while drinking coffee or hot chocolate during the winter.
Most importantly, though, that extra living space that caused you to have the addition built in the first place doesn’t disappear for 25% of the year.
Keep in mind, though, running the heating and HVAC to the addition will cost money, so how you intend to use the sunroom will guide which is the right choice for you. If you’re still deciding between the two, our three-season room page breaks down the cost and year-round usability differences to help you choose the right fit for your home.
Midwest Builders only uses the highest quality windows, insulation, and other materials to ensure your four seasons room will keep you cool in the summer and warm in the winter without increasing your energy bill.
Not only will a four seasons room increase the square footage of your home, but it will also add to your curb appeal and the overall value of your home. It is truly a return on investment!
Every four-season room from Midwest Builders is built to function as true year-round living space, not just an extra room that only works part of the year. That means:

A three-season room isn’t connected to your home’s heating and air conditioning, so it’s best used spring through fall. A four-season room ties directly into your home’s HVAC system, so you can use the space comfortably in every season, including Iowa winters.
Most four-season room additions require a building permit, since they’re a permanent, insulated structure tied into your home’s systems. Midwest Builders is licensed for the state of Iowa and can help guide you through the permitting process.
Timelines vary based on the size of the addition, materials selected, and current project scheduling. Our team can give you a personalized estimate for your four-season room builder project once we understand the scope during your free consultation.
Yes — a well-built four-season room adds functional square footage and curb appeal, which can increase your home’s resale value. Since it’s usable year-round rather than seasonally, it often adds more value than a three-season room or open patio.
