Benchwork L-girder or butt joint - maybe both?

John, I have nothing more to add to what I replied on your other topic.  I'm following along to see how it goes as I hope to be able to visit you someday as construction progresses.

John, Did you look into using cantilever construction off the walls or is it even possible with your room. I used that method to get rid of as many legs as possible and it works for me.

This is an old CAD drawing of what I did. I also ran tracks through and down the knee walls but mine is an attic room.

Your layout looks like it will be a winner.

Ray has a good point, John!  Contelievered 30" shelf bolted down to 18" 1000-pound rated metal brackets from Lowes is the cheaters (poor carpenter) way I did it.  Rock solid with a front 1" fascia board.

If you use cantilevers, you can either do them with wood or top each bracket with wood I use so you can still use risers to support elevation changes pretty much the same way you’d do with L-girder. You can also use the brackets all around and simply add some indented legs with an L-girder where the decking is deeper. While I favor flat decking, I’m assuming you want the landscape with ravines and hills, so cookie-cutter open decking would be the way to go.

Hi, Thanks for the awesome drawings! Two of my three walls are plaster board glued to foam insulation boards. Cannot drill deep enough to hit cement. There maybe some metal brackets they used to put up the foam board but I cannot trust them to hold anything. Your benchwork looks like it affords lots of access with lots of stability.

Well that answers that!  I wasn’t thinking about the exterior concrete walls being covered in that way.  And I used Mianne along my one brick wall because I didn’t want to put lag bolts into the brick wall.
