On this week's edition of the Sunday Special, the storytelling show Re:Sound looks at who built it...and who came.
In rural Crossville, Tennessee, you'll find a peculiar mansion, 15,500 square feet and eight stories high.
It also spans seven trees. It's the world's largest tree house. And the man who built it paid a dear price for it.
And we'll also poke around some ruins near San Francisco, and try to imagine that they were once part of a palatial swimming pool and amusement park built in 1898.
Join us for the Re:Sound special If You Build It, on the Sunday Special, Sunday afternoons at 5 on KSUT.
