Sunrooms exist in that kind of hazy Twilight Zone of addition-building. Is it really an addition? Does it qualify as a real structure? And how much do sunrooms cost anyway?
The problem is that you cannot get a fix on the price of a sunroom without having a nasty salesperson call on you and give you the hard sell. That doesn’t sound very good, does it?
If you want a “short answer,” I’ll give you a $10,000 to $15,000 cost estimate for an average sunroom. For a more nuanced answer, read on…
Cost of “Average” Sunroom
First, it depends on the type of sunroom you want. DoItYourself.com has what I think is a pretty good fix on Your Basic Ordinary Sunroom, which they define as having:
- A standard knee-wall
- Half glassed
- Solid roof sunroom
- 400 square feet
Estimate: about $10,000. I am inclined to go higher than that: $15,000.
Cost of Owens-Corning Sunroom: Ouch!
But what about a fancy, complete package sunroom? The Owens Corning SunSuites® Sunroom is one such no-hold-barred sunroom, with a fiberglass frame, integrated electrical system, roof, and a generous amount of glass.
Thanks to a promotional contest run by Owens Corning, we can fix the cost of this sunroom at about $40,000.
