How thick is the Birch ply you used? I am thinking 1/2 or 3/4 for the seat tops and 1/4 for the sides or maybe 1/2 inch all over. I keep thinking to myself "keep it light weight".
Yes, I had a concern about the
weight also and there was no need to overbuild it. Ply is 1/4" on the sides and I think 3/8" on the seat tops.
Clive, a couple more things. Where your table is attached just below the front window, did you use the existing narrow ledge where the upper bunk was originaly hinged from?
Not sure about a bunk, there wasn't one when I got it, just the goucho. But it's attached to the "window ledge" that was there already which is at the same height as for the table at back. So with the raised floor section it works out just right.
Second - Below the table (between the two seats) I see a narrow ledge and what appears to be a piano hinge. Is that a small storage compartment?
Yes, that is more storage. You are correct on it being a piano hinge. That space also allows for a 110v outlet to go there.
Thirdly (can't stop at two things) - What is the thickness of your table top?
Table, all doors, and the countertop are all 1/2" Birch ply.
