Hi all, I'm thinking of adding an extension to current benchtop as breakfast bar.
I've never done similar project so not sure if my idea works.
This is my current benchtop, 154cm x 64cm.

Got an online idea like this

Without breaking existing benchtop I'm thinking of adding a laminate on top of it.

Apologize for my poor drawing, does this idea work? What's the usual bar depth? For an example of 30cm depth, should I put 30cm on overlapping section? What should I use to glue the extension to current? Suppose I'll screw the 3 shelf brackets to cupboard and pine, how do I connect the pine to extension? Basically I want to make sure the extension is well supported and robust.
