Waschmaschine und Trockner Schrank-besondere Fall

Schlosserei or similar help needed! In our Abstellraum, we had to build a Sockel (about 80x80) to move the water supply to another location since we changed the arrangement of the kitchen and Abstellraum. Now we want to put wasching machine and Trockner in the Abstellraum but the wall has a bit of bottom part which is projecting out of rest of the wall. The place to keep the washing machine is restricted and we would like to use the projected area as base and elevate the bottom so that washing machine can be put at an elevation. Now we don’t know who can help us designing such a stand with one side let’s say 90cm and another 10cm. Any suggestion? Has anyone done some work like this?
