    BRING THE OUTDOORS INTO EVERYDAY LIFE

    A Sunroom That Feels Like Part of Your Home

    Many homeowners across the Greater Eastside love where they live but wish their home felt brighter, more open, or better connected to the outdoors.

    Sometimes it’s a lack of natural light. Sometimes it’s the desire for more usable living space. Other times it’s simply wanting a place to relax, gather with family, or enjoy the beauty of the backyard throughout the year.

    A custom sunroom can solve all of those challenges while creating a space that feels like it has always belonged.

    At Sun Spaces, every sunroom is designed around the architecture of the home, the surrounding property, and how the space will actually be used. The goal is not simply to add square footage. It is to create a comfortable, beautiful living environment that enhances the way you experience your home every day.

    Sunrooms with Skylights

    DESIGNED AROUND NATURAL LIGHT

    A Home That Feels More Open, Bright, and Connected

    One of the most noticeable transformations homeowners experience after adding a sunroom is how much brighter the home feels. Many custom sunrooms are designed around large window systems, skylights, roof glazing, and open architectural layouts that bring daylight deep into the home. Natural light can make rooms feel larger, create a stronger connection to the outdoors, and help transform underused areas into some of the most inviting spaces in the house. Because every home is different, each design is customized to take advantage of views, orientation, and the surrounding property.

    DESIGNED FOR THE GREATER EASTSIDE CLIMATE

    Can a Sunroom Be Comfortable Year Round in Washington?

    Yes, when it is designed and built correctly.

    Homes throughout Bellevue, Kirkland, Redmond, Issaquah, and the Greater Eastside experience changing weather throughout the year. A properly designed sunroom should provide comfort, natural light, and usability regardless of the season.

    Sun Spaces designs permanent residential additions intended for everyday use rather than temporary or seasonal enclosures.

    Features may include:

    • Energy-efficient windows and doors
    • Insulated roof and wall systems
    • Integrated HVAC planning
    • Moisture management and ventilation
    • Structural framing
    • Roofing systems designed to integrate with the home

    The result is a bright, comfortable living space designed to be enjoyed throughout the year.
