The annotated kitchen plan is attached. If you roll your mouse over the speech bubbles there is a little more info.
The kitchen designer says that the plans are drawn to a 1:20 scale.
I can confirm that on the above plan the yellow line covers four 600mm cupboards or their equivalent with a 600mm depth plus of course the 20mm overhang. The walls are not perfectly square I suspect. I can ask for the worktops to be pulled a little forward if necessary and can buy 3050mm X 650mm worktop the comment made by the other supplier was as follows: 3050 x 650 x 25mm Minerva Sink Acrylic Designer White with RH Drainer (Sink on LH). Pre-drilled tap hole with recessed drainer area. Will fit into base cabinet openings over 650mm. Includes factory fitted combined 1.5 bowl acrylic sink and basket strainers.
I have drawn a yellow circle with lines to the right to show the position of the sink and draining board to the right. I would like the sink to be made from the white Minerva and to be a 1.5 designer bowl
The section at the bottom of the plan shaded yellow is at its maximum depth 760mm and a bit under 1600mm in width.
The payment is made in cash
