I tried to reply earlier but it didn't work... hmmm, strange stuff.
Anyway, Thanks for the suggestions. I won't be puting anything to heavy (like engine blocks

), just the usual stuff - sports and outdoor equipment, tools, everyday storage kinda stuff. I think brainchild has the right idea though, I'll just have sit and try to draw something out...
I don't want wall hanging shelves. I want free-standing units that I will bolt into the floor and maybe fasten to the walls.
I was thinking about using melamine(<--Spelling?) just cause it looks nicer. Not strong enough you think?
Sorry for my delayed response, I was having puter troubles this weekend
