Can this be placed on a wooden flooring system similar to this? (https://timberframehq.com/shop/12×16-post-and-beam-cabin/)
And what is the height of the 6:12 roof pitch?
Thank you!
Is there a difference between the King post and Timber frame other than the 4′? They look the same…
Yes, you could place this on a wooden flooring system. The height to the top of the rafters for the 6:12 is 14′-4 3/4″
Thank you Katrina, very helpful!
They are the same, only difference is the 4′ you mentioned.
What additional engineering would you need for the Houston area since we experience hurricanes every summer?
We would recommend that you get the plan looked at by an engineer so he can run the calculations and verify the connections given your location. If you would like us to run that by our engineer, reach out to us at sales@timberframehq.com.
I assume that the 16×20 pavilion uses 8×8 posts? If I built this structure, I would fill in the sides with additional timbers on either side of the doors and windows. If you added additional timbers could be posts be scaled down to 6×6? I am thinking about handling such large timbers
The posts are indeed 8×8. We could never recommend your downsizing the timbers without consulting an engineer.
Is the frame tall enough to do lean to sheds off the sides of the frame with conventional framing?
It is 8′-7″ to the top of the bent girt which is about the same as the bottom of the rafters.
Do you think going 2 ft taller would significantly cause more stress on the posts?
No it will not increase any loads on the building or posts, go for it.
Is the listed dimension of the building size the outside of post?
Yes, it is outside of the post to outside of the post. There is also a two-foot overhang on all four sides, giving you 20×24 under the roof.
