If You Build It, They Will Come

The builder of this 8,000 square foot treehouse was told in a vision that if he built it, he would never run out of materials. So he did, and he didn't, and yes, they do come -- 400-500 a week come to visit this rustic record-setting treehouse near Crossville, Tennessee.

Although he never bothered to measure Minister’s House (he estimates it must be about 8,000 to 10,000 square feet), he did count the nails he had to hammer into it, 258,000. It cost the 56-year-old landscape architect around $12,000 to construct the world’s biggest treehouse.
400-500 people visit Minister’s House every week, most of them tourists from out of state who heard about a 10-story-treehouse somewhere in Tennessee. _Oddity
