    Love this porch, more importantly The Wife loves it, too. Especially the mockup as shown.

    How much effort to extend the roof line back to the roof of our house?

    Would the roof’s need to be connected to the house or could you just get it as close as possible. My roof line is like the one in the diagram and I’m not ready to do any roof work to my house even though I know it’s easy I would like to do it later if at all possible. Love the design of this though.

      I think that you can get by with as close as possible. Just make sure that you line up the roof lines properly and you should be good to go. A wide piece of flashing could be used to cover up the gap in the short term to prevent too much water damage from having to the frame before you tie the roof together.

    Will 4 6x6s hold the weight of the roof and the snow. ( I am in Chicago)?

      No, I would stick with the 8×8 posts. With the joinery currently in the plan too much wood from the posts and beams are removed so, you need the extra meat in the timbers to support the frame, lateral and roof loads.

    Love your site! I’m very interested in using beams and posts from an old farm on family land to build a simple timber frame pavilion. We’re in West Virginia and there are PLENTY of rocks that would make great field stone piers (is that what they’re called?).

    Here’s my question – in a nutshell, could you please explain how this would be done? I’m thinking we’d need a good foundation, then build the piers from stone, and then top with the beams from the barn. But I’m not sure. If you could give a little light on this, I’d surely appreciate it!

    Thank you!

    This is what I’m looking for however I really need it to be no more then 9 or 10 foot deep. Is it possible to modify the plan for this? It going to be centered with my pool however I’m running out of yard.

      I don’t have one of these plan preplanned that short however, it is easily shorten but just reducing the length of the plates and ridge. I can help with adjusting the rafter spacing just let me know what the final depth is.

    Great layout! What type of wood do you recommend using for the posts? Should they be pretreated or can i stain them after?

    • Brice Cochran November 23, 2016 at 8:40 am #

      I would recommend that you finish the timbers right before or right after the raising. If it is outdoors a water based finish is the way to go to allow the timber to breathe a little better.

    Sounds like a great project, thanks for the comment.
