Hopefully this works. My webshot pictures havn't been wanting to attach to forums recently. Sorry no photos, as I don't have a digital camera.
This is a drawing of the whole thing, as it will be made.
This is a drawing of the supports as you would see them looking from the ceiling to the floor. Measurements are in mm, and the measurements on the right hand side are a mirror image of the ones on the left. The front of the cabinet is the side with the 2500mm measurement on it, and there are two doors on the two left compartments, and two on the right hand compartments. The middle one is just a panel. The second compartment from the left and the right has a shelf about 2/3 of the way up from the top.
This is a drawing of the base and its supports that will be built behind the skirting on the very bottom of the cabinet (see drawing 1). The support section in drawing 2 will be sitting ontop of a sheet of mdf that will sit ontop of the supports in drawing 3 (have I lost you yet? ) The grey bits are the matrix that has been built out of 2x4 wood (the only wood component of the structure. They are positioned in an off centre manner so that they can basically be screwed in place.
