  1. 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?


  2. 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.

  3. 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.

  4. 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.

  5. 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!

  7. 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.

  8. 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.

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

  10. 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.

  11. I would like to know if possible if you have plans available for a porch 8′ x 16′ with a 6/12 Roof pitch.

    Please let me know if these plans are available. If not, then how much would plans cost for these dimensions.

    Thank you.

  12. Hello I have interest in the timber frame porch I want it from left to right 20’ and out 18 w that same design I like the way it valleys into the roof but don’t want it to touch my roof want to place as close I can to my overhang from my house I am Trina to buy these plans ASAP thanks my number is 8315241519 Luis

  13. Katrina Williams

    Joe, we have this plan available – there is an 8′ deep variation. It would be pretty simple to shorten the length, but the it is a 3/12 pitch.

  14. Katrina Williams

    Dave, it is 14′-9 1/16″ from bottom of post to top of ridge beam, and 11 7/16″ additional to top of rafter

  15. I’ve built a pavilion using your 16 x 12 plan and everything turned out great. I’m now wishing to do the same size design as a front porch like the one above. I know I will have to get my valley and fascia points in alignment, and what I’m wondering is whether or not your over hang dimensions are accounting for fascia trim or do I have make modifications and adjustments myself in this area? In retrospect to the plan above most everything seems pretty much the same as the pavilion plans. But of course I prefer on a porch to install gutters and the need for nice fascia.

  16. excellent website and info;thank you! Construction of my house in the NC mountains is already underway. I am interested in a hybrid of two of your plans. I likely need to speak with you regarding your custom design options but for now I have a simple question. Have you (can you) designed a timber frame porch similar to your 12X16 model but with a hammer beam truss? Thanks in advance for any info you can provide.

  17. Katrina Williams

    No, Steve, we do not have a design for a 12×16 hammer beam. Please check out this page for more information on our custom design options.

  18. The porch roof pitch I am following is a 4/12 pitch. How do I get the plans for that instead of the 8/12 pitch

  19. Katrina Williams

    Luke, While the plan has an 8″ roof pitch by default we have added the dimensions for 3, 4, 5, 6, 7, 9, 10, 11, 12-inch roof pitches to allow you the option to choose.

  20. Thanks! I have yet to timber frame and wanted to learn. Plus I need cover over my deck anyway.

  21. I’m looking for a pavilion about 24’ wide and 16’ deep it would go over my patio and attach to my house like your 12X16

  22. Hello, I am looking at building a timber frame pavilion for my patio that is being poured. I was planning on putting sonotubes under the concrete patio to support the timber frame. I was looking at the 12×16 timber frame King post plan it states that it is 12wide x 16 deep on the outside of the posts. I then saw the 12×16 timber frame porch drawing but the width and length are switched. I like that the porch comes with different options for pitch but I am looking for the 12 wide x 16 in length. Can the porch plan be easily modified to these dimensions or do you have different pitch plans available for the king post pavilion plans?

  23. Katrina Williams

    Tom, the 12×16 king post plans do not come with different pitch options. Modifying a plan perpendicular to the ridge is not a quick and easy change. We do offer custom design services; you can find out more about them here.
