Four-Season Sunrooms for Year-Round Enjoyment

Our four-season sunrooms in NOVA offer year-round enjoyment for the entire family. They’re great for enjoying the beauty of the outdoors throughout all the seasons. Our four-season sunrooms have built-in heating, so they remain comfortable even during the coldest winter days.

Three-Season Rooms for Spring, Summer, and Fall

Another popular sunroom option is the three-season room. These are more budget-friendly for those looking for affordable home expansion without the larger price tag. Our three-season rooms don’t have heating, making them an ideal option for use during the spring, summer, and fall. They make a great scenic retreat where you can enjoy the many benefits of natural sunlight.

Custom Flooring, Skylights, and Window Walls

All our sunrooms are custom-designed to meet your unique preferences. From the flooring we use to skylight installations and even the windows on your walls are selected by you with the help of our highly knowledgeable design team. We offer many high-efficiency windows, insulation, and climate control options for your new space.

Sunroom Addition FAQs

Because sunrooms are a popular home addition option, we receive many questions about them. Below, we’ll address some of the most common so you can learn more about these great spaces.

What’s the difference between a three-season and four-season sunroom?

The main difference between a three-season sunroom and a four-season one is heating. Four-season rooms have built-in heating to keep them comfortably warm so that you can use them during the winter months. Three-season rooms lack heating, making them usable from spring through fall.

Do sunroom additions increase my home’s resale value?

Yes, sunrooms will increase your home’s resale value by adding more enclosed living space to your home. Many homebuyers even consider sunrooms to have a higher perceived value than simple home additions, like living room expansions.
