I built this for my fire pit area. I used #2 Prime pressure treated pine. (ground contact) I have about $100 invested. ($80.00 in lumber and about $20.00 in screws and hinges) That doesn’t include any finish I decide to use. I love the concept and always wanted to build one. This is a great straight forward plan that’s easy to follow. You’ll notice I removed 3.5” from each side of the table top. I’m a rather large man and felt like I was leaning back sitting at the table. Not at all comfortable. Removing the 3.5” solved the problem.
