Four-Season LivingSpace Sunrooms in Appleton, WI
It's more than a sunroom — it's an investment. As a LivingSpace dealer, ModernXscapes builds code-compliant rooms that add real square footage to your home instead of an enclosure you close off every winter.

Adds Real Estate By The Square Foot.
Most patio enclosures are a seasonal room bolted onto a house. A LivingSpace sunroom is engineered, permitted, and finished as living area — the kind of space that counts when you list the home and the kind you actually use in February. Whether you plan to sell or stay forever, the square footage is real.
Three Ways In
How A Sunroom Becomes Part Of Your Home.
Extend off an existing space
Build off a deck or slab already in place. The engineered floor panels arrive pre-insulated and moisture-protected, so the new room starts dry and stays dry.
Integrate with a new structure
Plan the sunroom alongside a new deck, pergola, or pool build so the whole backyard is designed and permitted as one project by one team.
Why LivingSpace
Warm Winters & Cool Summers.
Adds Real Square Footage
A LivingSpace room is built to residential building code, so it counts as living area rather than a bolt-on enclosure. Whether you sell or stay, you are building equity.
Warm Winters, Cool Summers
Engineered to meet thermal efficiency requirements in northern climates. The room does not have to be walled off from the rest of the house every October.
R-Value Above Most Homes
The patented load-bearing frame exceeds the R-value of most home walls and leaves chases for electrical, so lights and outlets go where you want them.
Made For Your Opening
Every component is pre-cut in the factory and every window is tailor-made. No general-purpose windows, no prefab kit forced onto your house.
Heating & Cooling Options
Depending on your home's layout, extra HVAC may not be needed at all. When it is, the system has mini-split and in-floor options ready.
Finished Like The House
Wood floors, decorative trim, woodplank ceilings, recessed lighting, even a fireplace. Inside and out, it reads as part of the home — not an add-on.

The Process
Five Steps From Patio To Living Room.
01
Foundation & Floor
Convert an existing covered space, build off a deck, or add a new slab, deck, or steel piles. Engineered deck panels — pre-insulated and moisture-protected — form the floor.
02
Frame & Materials
Every piece is pre-cut in the factory for exact assembly. The patented system is load-bearing, exceeds the R-value of most homes, and carries electrical inside the frame.
03
Glass
Like the frame, every window is tailor-made for your project and slides right into place. No general-purpose windows, no prefab shortcuts.
04
Heating & Cooling
Year-round usability is the point. Depending on the layout of your home, added HVAC may not be necessary — and when it is, we size it during design.
05
Finishing Details
Flooring, trim, ceilings, lighting, and any final touches, completed by our Appleton crew so the room matches the rest of the house.

FAQ
Sunroom Questions, Answered.
What is a patio conversion?
A patio conversion takes a covered patio, screen porch, or three-season room you already have and rebuilds it as an insulated, code-built four-season room. It is usually the fastest and least disruptive way to gain living space, because the footprint and often the roof are already there.
Is a sunroom the same as a Lumon glass enclosure?
No. A LivingSpace sunroom is a sealed, insulated, code-built room that counts as living area. Lumon patio glazing is an unheated retractable glass enclosure that opens completely. If you want the space open in summer, look at Lumon Glass; if you want a heated room usable in January, you want a sunroom.
Can it be used through a Wisconsin winter?
Yes. The system is built to meet code and thermal efficiency requirements in northern climates, with an R-value that exceeds most home walls, so the room stays comfortable in winter and does not need to be closed off from the house.
Does it need its own furnace or air conditioning?
Not always. Depending on your home's existing system and layout, the room may work off what you already have. When additional heating or cooling makes sense, we plan it in during design rather than adding it later.
Can I build on my existing deck?
Often, yes — it depends on the framing, footings, and condition of the deck. We evaluate the structure during the estimate and tell you plainly if it needs reinforcement or replacement first.
What does a sunroom cost?
[PLACEHOLDER: sunroom project price range]. Pricing depends on size, foundation type, glass package, and interior finishes. We give you a firm number after the on-site design consultation.
Do you serve my area?
We build sunrooms and patio conversions throughout Appleton, the Fox Valley, Green Bay, Oshkosh, Fond du Lac, and communities within roughly 100 miles of Appleton, WI.
