The Glass Room That Doesn't Cost $47,000
Most homeowners think a proper glass room means $40,000, a contractor, and two months of disruption. They're working from old information.

Where the $47,000 actually goes
A typical sunroom in the U.S. runs $22,000 to $75,000. The average four-season build lands around $47,000.
Most of that isn't the glass. It's the build. Site prep, foundation, framing, electrical, permits, and weeks of contractor crews on site. Labor alone is 40 to 60 percent of the project. Foundation and windows take another large share.

On a 12×12 four-season build, the construction work alone can exceed the cost of all the glass and framing combined.
That's why most people get the quote, sit on it for a week, and quietly decide a glass room isn't for them.
Three ways to get a glass room. One does the math.
Same footprint. Same use case. Same goal - a year-round room with light on every side. The numbers tell the rest.

So what is a Scandiglas, exactly
It's not a sunroom. It's not a basic kit either.
Scandiglas is a fully glazed glass room shipped flat-pack to the door. Tempered safety glass on every wall - up to seven times stronger than standard glass. A clear glass roof, standard. A reinforced aluminum frame rated for winds up to 115 mph and heavy snow loads. Two adults assemble it in a weekend with the included instructions.
Owners use them as morning rooms, plant studios, dining add-ons, home offices, and tea rooms. Tempered glass transmits up to 95% of available light, so the room stays bright in winter. Full 6'7" interior height. The structure reads as architecture, not as a shed with windows.
The two models most buyers compare
One is bigger. One is cheaper. Both have the glass roof.

Why now, in plain numbers
No countdown timer. No "limited spots left." Just the timing as it actually stands.
If a glass room is on the list this year, the math says the next three weeks are the cheapest it gets.
