The arbour dimensions are approximately 12 feet wide by 4 feet deep. From ground level to the underside of the arbour rafters is approximately 7.5 feet. From inside both posts, the distance can be 10 feet wide when using 2 inch by 8 inch support joists. Cost will vary based on time of year and region because of constantly changing lumber prices. The lumber used for this project is Western Red Cedar. Thanks for your interest, and we'll be happy to answer any other questions you may have!

Thank you very much, I really appreciate it!
