Mohawk Performing Arts Center

We are designing the interior space of an open air arts pavilion at a day camp. There are several program area rooms and I need help laying out the cabinets, closets, counter tops and furniture in each program room. I want to see various layouts for the rooms, I can provide the contents and measurements. I also would to see 3-D versions too, it's hard to imagine what things will look like when the space doesn't exist yet ;-) We are currently in the dead of winter in NY so it's too cold to pour the concrete for the 2nd level, I am having to design the rooms before they exist, which is why I need help envisioning.
