Topic: Rich Guy Treehouse

I've been researching using a tree for the center of a spiral staircase for accessing  an elevated deck. Anyone got any suggestions?

In the mean time I found this tree house with a budget. As you get into the thread you realize the budget he must have for not just lumber and  equipment,  but for stainless rod to put into the tree, and 6" 6061 square stock to make  the supports for the stairs.  I haven't found where he talks about what  he's spent.

WTF?

use an auger and drill into the tree. Drive 1" steel rods into the tree. Fashion your stair treads from wood (or other suitable exterior material) but secure them to metal frames. Bolt the frames to the steel rods. (You'll want to fabricate each frame section first, then use a template to locate the rods on the tree. Then drill the rods into the trees. I'd encourage you to sink the rods at least 8" into the tree, maybe 12".)

Making a spiral stair requires lots of math to insure proper rotation and riser heights.

I figured it would be more involved than using  the lumber and other materials on hand, and   beyond my employer's budget.  It would have been a nice touch.   I do have enough 2x12 to do a regular straight staircase and maybe I'll just use the tree to support it.

Here's an interesting site:  www.stairporn.org

There's even  a whole  staircase there  on Oz that was carved through the center of a 50 ton 45,000 year old tree.
