Look at the bright side, you have more than twice as much space as you will at competition.

You will likely have to store a pit structue of kinds, so, make your pit really useful and have it setup all the time. You shouldn't need many more tools that you can store in a well organized pit.
Suggestion: This year we created 2- 2X5 ft rolling tables with drawers in each. One was setup for light duty (electrical, image, ect) one was setup for heavy duty (drills, scrap metal, saws, ect.) Something like this could help alot because it can be used in your area as a table and storage device as well as at the competition. AND, you will be familar with the storage at competition which will save SO much time.

Start with a list of what items you need.
It might start like this:
-White board (and markers)
-X number of computers
-cordless tools
-Drill bits and saw blades

The cool thing about a small area is that any team will have the manpower to turn that area into something great. You can have images on every inch of space, every drawer packed with the essesentials.
