Hey
Can you modifie the dimension for a larger pavillon like 16′ instead of the 12′ on the plan
Simon, please check out our custom design services here. We can certainly modify that plan.
Do your plans include cut sheets? Do you have an example of what they may look like?
John, click on the images just below “Download Sample PLans” for an example of the cut sheets.
Hi, how do I change length of pavilion to 24 feet?
Has anyone built this? Curious about what the lumber cost is.
Timber prices vary by region and species, so there is no one answer to your question. We can tell you that this frame utilizes 4281 board feet. That should give you a starting point in getting prices.
Good evening, I was wondering if you ever put together a 16′ plan like Simon was asking about. I would like this plan but In 16′ or even better 20′.
Thank you
W do not have a stock plan as you describe but could help you through our custom design department.
