I’m building a free standing treehouse out of mostly recycled lumber from a deck I had rebuilt last year.
It will be a 16×16 deck with a 12×12 fort atop the deck. Probably 6 feet above the ground.
I’m building over a 9×12 concrete slab that was just sitting there when I bought the house and I’ll dig post holes and use concrete footings to complete the 16×16 footprint.
Most of the 2×6 deck boards were salvaged but the 2×8 joists were hauled away. Are 2×6’s sufficient for joists?
How about 4×4 posts?
How far apart should I space posts?

Thank you

You would need three headers/beams to support the deck with 2×6 joists. With it being elevated there also needs to be diagonal bracing from the posts to the beams and deck.
Have you checked with the building dept? They could give you more info as well.

Thanks for the tips.
I’m going to use 6×6 posts, double 2×10 beams in notched posts and 2×8 joists. And diagonal bracing as Gary mentioned, possibly also under the joists.
I’m wondering about the spacing of the joists and posts.
My initial plan was to space posts 4” apart in all directions. That would require 20 posts. It seems like overkill but I’ve already bought the joists and from what I’ve read, I can’t span 16” with them.
Any suggestions would be appreciated.
Thanks

gbarron – I would use 16” on center for the joists. If you are going to use a composite for the decking, 12” may be in order.

Luong – It seems that you have the same comment for every post on this site – you need to call a contractor in order to do it right. Well, some of us are or have been contractors and others are looking at doing it right – where poor contractors did something stupid in the past.

If you are not going to offer real advise – then don’t offer anything.

This goes for millicater and rhonan as well.

Just my 2 or 3 cents.
