Just the lumber is about $1,500, and that's the low-priced wood. If you get cedar wood, then double that price. I think 3k to 5k of just material. If you need cement patio then add another 6k. So about 15k - 20k if you hire someone.
Thanks for the build video because I want to build the same thing. But what is with the "music". I can't stand it so much I am switching off the sound.
