I have found kitchen units made of birch ply, they look solid, but I’m wondering if there is any need, once cupboards are fitted in place I’ve never really found problems with cabinets, it’s normally doors and drawers that start going scabby, are they worth the extra. 

 

Morning mods, if you want to stick this question in with my other one on kitchens that will be cool. 

Birch ply is fantastic if you are leaving the ply face and edges visible as a feature, if not they are more trouble than they are worth. Yes ply is pretty stable, but its still a wood and will move unlike good quality chipboard. I made all my workshop units from marine ply and they stil;l; move and drawers bind due to atmospheric changes
