Hi, My father has been dedicating a lot of his time to making our soon-to-be home as "rewarding" (I guess) and as nice as possible for when its done. The new side project would be this. It is supposed to be some rain-proof place for a bench/table outside. There are gonna be three (more or less if needed) structures like the one in the picture, parallel to each other, with some sort of material (haven't figured it out yet) to make a nice rain-proof spot for a bench or a table. What inspired him: My question to you is: does this structure look stable, ready to build? are there any improvements that can be done? Neither of us work with CAD or software like this and our budget is quite limited for this project, so asking people around is pretty much all the expertise we're gonna get. Thank you.
