I recently made a workbench that can go on a benchtop (e.g. the kitchen bench <wink>). It is made of laminated European beech, the top is glued together with epoxy (difficulty getting sufficient clamping) and the remainder of gluining is using polyurethane glue. A sheet of 2200x600x26mm was used and final size works out at 880x470x105mm.
Veritas parts were used to build it and these are later usefull for holding the work. Pictures should speak for themselves.
