So my kitchen fitting process is going well, just the wall units to fit now which I thought was a fairly easy job until DISASTER, my mum just told me you can't put wall units on a stud wall. The wall has no brickwork in it, literally just two bits of plaster board and wood. (Which is odd and the stairs run up one side) I bought the metal plaster board plugs: https://www.screwfix.com/p/rawlplug...gclsrc=aw.ds&dclid=CPXI1Pi3sN0CFULS3godDeIPjA which are great, but mum says just plaster board won't support the weight of the units. Unfortunately this is where pretty much all my wall units have been planned to go (kitchen designer never asked what kind of wall it was) including my glass fronted ones. What are my options, my very expensive glass doors are not returnable and I'd rather have no wall units. I've already installed the base cabinet, worktop and tiles . Only suggestion my mum came up with was to remove the plaster board from the other side and brick up behind the kitchen side plaster board. Can imagine this would be a pretty hefty job and the stairs are there. Please Help!
