Shelf design

We are in need of shelf space for all the documents and books. Mostly Iron-wife's. Me, PDF on my computers or maybe a Kindle ;-)

Here's a design I drew up based on an architect's proposed design. The desks we already have. Just the shelves. They are modular, total of 7 modules.

I didn't draw the design by hand. I have used Google's Sketch-up; it's free. And actually with this program I had dismissed someone's else design.

Take a look at the design from the rendition.
