Just realised the depth I need is not there . Plates are 260mm and my wall cabinets have a depth of 270mm minus the backing and the door don’t think it’s wide enough .
Guess will have to pop them on the trolley.
The other alternative is this bridging shelf in pine.
I’ll need to go to IKEA today to buy the trolleys and the wall unit. Might have to bring one of the kids to help me lift it into the car.
