How much exposure would there be to wind in the location you're looking to install this?

Are you planning on putting roofing tile/shingles on the top?

Will the structure be placed on soil/gravel/concrete/etc.?

How will you be fastening the columns/beams (i.e.: galvanized angle iron, etc.)?

It's fine for a quick kayak shelter.

One thing I'd change: it's always best to build horizontal beams on top of vertical posts, rather than bolt beams onto the side of posts as you've illustrated. This transfers the load directly rather than relying on the shear strength of your fasteners.

Edit: how's this going to be anchored to the ground?

Google “rafter span table” or “rafter size chart” to get info on what dimension lumber you should be using for various parts of the project. It also depends on where you are located. If this structure will be expected to handle a snow load for example then it’s critical you build it to handle that. What do your local codes have to say about standards for similar structures in that regard?

Youve got thin bits of wood perpendicular to the length of the roof. I would perhaps consider using thicker posts or square beams for these. You wouldnt want wind to blow it over, and those thin sides could be a vulnerability.

I would also concrete them into the ground at least a foot, maybe foot and a half.

Roof likes fine. If its just for a kayak it really doesnt need to be fort knox.

No because the whole structure is a sailboat with that angled roof

More advanced than me. I put mine outside, under a tree, on two horses and wrapped it with rain tarp. Called it a day.

Thanks for the tips. No snow here in coastal Texas usually. But I'll look into it.

The tall side would be near a wooden fence that is taller than my structure.

The tall side will go against a fence, and while further away, the house will mitigate wind from the other side.

Yes, shingles.

I was planning on grass, and using ground contact rated lumber for the 4x4 and vertical posts.

I was planning on buying or renting a framing nailer. I've never done this before, but am fairly capable if I know what to do, which is why I'm asking here.

The plan was weight, but I think maybe the best route may be to extend the vertical posts and drive them into the ground a few feet?

Good point on the load transfer, I'll redesign that, thank you!

Rather than nails - I'd recommend wood screws and angle iron like these ties commonly found at most hardware/DIY stores.

Looks stable side-to-side (long-ways), but needs diagonal stabilizers front to back too. Smaller is fine, and actually, your other diagonals could probably be a lot smaller.

The vertical posts need to be 4x4s, and if you're doing that, make them tall enough to stand under without banging your head. You can hang the kayak(s) and equipment on the posts instead of on the ground that way, too.

I also suggest that you cut the tips of the long 2x4s at a 45 degree angle to minimize head bruises. Very simple miter saw cut.

All very good points. Will incorporate into my second draft!'

Don't know about hanging it. The yak is over 100 lbs. I'll look into options that are rated for that much weight. I definitely don't want to hang by the handles, because they are secured with rivets. Good enough to move around, but don't think they're intended to be used as long term weight bearing.

What if your horses need to go eat?

Put your vertical post on top of the 4*4 laying on the ground. That will keep your post out of the dirt and reduce the rot.

Just make sure you pin it to the ground. A gust of wind hitting that the wrong way would flip it over quickly.

Not at all.

Very little code enforcement too, if memory serves.

I wouldn't put a 2x4 on its side to support any roof load. Up that to a 2x6. Notch the post and set it in.

4x4 posts for the uprights put them on pier block, or better yet, cement them into the ground
Front to back bracing
Add some strong ties to the diagonals... they'll hold better

You know most people would just buy a tarp.

Design something that would support it, but fits into it lying on the ground, then mound that to the posts.

Maybe, but I wasn't looking for recommendations on whether this was overkill. I did that in Hawaii, and it constantly got pools of water in the cover that was a pain. I'll still be covering it, but mainly for sun protection of the gear on top. It's a fishing yak

No.

I don't know but it looks like a strong breeze could use that roof like a sail. I would definitely mount the veritical 2x4?s to the ground maybe just some concrete cylinders you set them in.

Get yourself some Simpson 3" SDS screws and a cordless impact driver. Works great for those flat "face nail" connections.

Taller structure may also fit two yaks if it needs to

Im an engineer and “carpenter” (come from family of carpenters and have helped my dad for a number of years. I know a decent amount in the trade)

This needs to be tied to the ground. I’d set 4x4s at least 2-3’ feet into the ground with concrete for the post. The 4x4 (?) joist you have the girders (what the kayak will rest on) sitting on could be switched to 2x6s and elevated off the ground.

The beam on the front and back which support the roof need to be at minimum a double 2x6 to support that span and roof load. The rafters are fine to be 2x4s. You need a barge rafter to hold the rafter ends in position. The over handing decking in the end with no rafter is no bueno. Decking cannot go unsupported for more than a few inches

The braces are fine. I’d probably add a short one on the side to tie back to the middle

Feel free to pm me for any other questions! Or reply to this

Thanks so much! This is why I posted my question! :) I got a while before I'll be building it, so when I get to a second draft, I'll take you up on the p.m. Thanks again.
