What Is a 3 Season Room?

A three season room in Milwaukee is an enclosed room addition with lots of windows that's built for spring, summer, and fall. Unlike a four-season sunroom, a 3 season room usually isn't insulated or connected to your home's heating and cooling, so it's mainly a warm-weather space. That keeps the cost lower than a full four-season addition. For a deeper explanation, see what a 3 season room is and why you might want one.

Screened 3 Season Rooms

A screened 3 season room combines screens for airflow with windows you can close when the weather turns. It's a good fit for homeowners who want summer breezes without the bugs.

Frequently Asked Questions

  • How long does it take to build a 3 season room?

With options like advanced HVAC systems, our sunrooms are designed for year-round enjoyment.

  • Can you use a 3 season room in winter?

    Our design approach is to complement and enhance your existing home design. Whether you have a modern, traditional, or eclectic style, we ensure that your sunroom feels like a natural extension of your home. From the type of windows to the style of roofing, every element is chosen to harmonize with your home’s architecture.

  • What's the difference between a 3 season room and a sunroom?

    "Sunroom" is the broader term. A 3 season room is a type of sunroom built for warmer months, while a four-season sunroom is insulated and heated for year-round use.

  • Are 3 season rooms energy-efficient?

    With energy-efficient glass and quality materials, they can be. A four-season room with proper insulation will be the most efficient option.

  • How much does a 3 season room cost?

    The cost of a 3 season room depends on its size, design, materials, foundation, windows, and other project requirements. Lakeside Deck Builders provides a free, detailed quote so you can understand the expected cost before construction begins.
