Call me crazy but I want to build something like this on my 10 acres so I can see all the way to the beach.
Given my wind speed and seismic zone I am probably looking at some serious holdowns at the first level (HDU 11). I would have to run the numbers but it would probably work. I would probably also sheath it with 5/8" plywood inside and out for some serious shearwall action, at least on the the first two floors. I'm thinking spiral staircases between levels to save as much floor space as possible and to make it more interesting. Minimal windows on the first three levels and then the top level would have alot of windows for the view. 11-7/8 TJI 210 for the floors with 3/4 sheathing T&G, 16" o/c.
The structure is 16'x16' with grade to top plate height of 38'8".
The roof is 6:12 pyramid hip with 2x8 rafters, I may go with a steeper pitch though.
Anyone design something goofy like this before. I don't know if my county building dept. would give it an approval though even if its engineered (stamped).
