Hopefully, within the month, I will be on my way of building a geodesic
The one I think I'm going to go with makes it simple. As it uses hubs and
all you do is bolt straight cut lumber into the hubs.
What I haven't decided on yet, is slab, or deck.
Since this will be in northern Florida, the frost line shouldn't really be
The dome will be 47ft in diameter. I'm thinking if I go with a deck, I
could just simply build a square one that is 55ft. Then I'd have 8ft all
way the around built in.
My idea is to level out two feet below ground, and build the deck two feet
above ground. Which would create a nice crawl space. For the floor of the
home itself, or maybe throughout, use 12" or 16" wood i-joists. with two
foot centers. As the only real weight on the inside floor will be dividing
Inside the home for the base of the floor, install plywood. Yes, I know how
to build decks as I've done them before. But not to code. I am aware that I
will need cement pilon footers every so many feet for the deck.
But what I'd like to know is, which would the cheaper route be?
Deck as described or slab with a 6" base?
