However you pronounce it. . . . we've got one like this being built.
We'd found the Castle Cupolas, which we really liked, but they wanted to charge us an extra $500 for an extension base (three extension bases - each an inch (?!) - to be precise) to fit our steeper-than-usual roof. That sounded high. "Vinyl is expensive." was the explanation. (?!)
I got back online and found the Amish Country Cupola place and for half the price, they're building us this splendid cupola and properly extended base & shipping it to us.
Sorry, Castle Cupola. . . .
