Basic, yes, but I'm a newbie. Just built a loft in my 10x12 shed. It spans 4' out from the edge on the 10' side and extends on the 12' side out 2' for the length of the shed. There is a shelf about 3' high across the whole 12' back wall. I actually laid down on the loft for a few minutes and it wasn't even twitching.
So, that's my weekend project. Roughly 6-7 hours as I was very deliberate about it. Can get pics if anyone wants to see... not a complex project but came out well for a first one.
