I'm going to build a cellar hatch. It's 735w x 1420l.
It will have hinges on the long side and I'll be getting 2 gas struts to hold it up when opening (like a car boot).
Along with the ply, on top of it will go 6mm ply + 20mm engineered wood floor - this is to keep it the same level as the rest of the floor when that gets done.
My question is, what thickness ply should I use? An adult couldn't walk on it, because of the head height, but my little kids might. And should I use hard or soft wood? I'm conscious of making it too heavy for the gas struts - I will need to specify the weight to the gas struts people at some point.
