I don't remember specifically what you are looking for, but there are on line how tos for turning storage cubes into a banquette...maybe that will get you close to where you need to go.

Here is a link that might be useful: Drawer base to banquette

Thank you very much...sure wish Christopher was back on the air, I really liked a lot of his ideas.

You and me both!

Thanks ogoopogo I've been enjoying watching the old shows!

I had a hard time designing our banquette because it is not straight. I found the best way is to buy large poster boards and cut the shape you want for your banquette. This will help the carpenter or cabinet maker.

Consider how wide you want the seat to be. If you plan to have a back rest built, they normally start out a bit deeper where it meets the bench. Also need to allow for an overhang if you intend to upholster. Overhang is probably not needed if you are just putting cushions. You should also consider the height. How high does the bench need to be in order to be chair level after cushion / upholstery is in place.
