Autocad drawing

I need to have this drawn in Autocad. It is a plan of a new unit - 900 square meters on the ground floor and 200 square meters upstairs. The oblong objects are water tanks. Upstairs would have an open planned office and a boardroom +plus toilet.
Downstairs would provide all the floor space plus store. Toys would include a freeze dryer (for conservation). We currently have got room for one so wooden finds have to go to York for final freeze dry. Also a Faro Arm for recording, an x-ray machine for finds.
