A while back I decided to build a centre console for my bus. The idea originally stemmed from the need for some cup holders, but ended up encompassing a whole lot more. Of course this gets rid of the walk through feature, but due to my size, I found I didn't really use it anyway.
I am no builder so aside from a very rough original plan of the supporting frame, the entire build was all fly by the seat of your pants stuff.

Frame was built using 19mm pine, wood "skin" was 12mm MDF and padding was 20mm foam covered in textured black vinyl.
I ended up including a few extra features as follows:
- Front open storage bin (near gear stick)
- Folding padded arm rest
- Switched blue LED illumination for storage bin under arm rest
- Moulded and padded iPod shelf
- Rear console containing DVD player/LCD monitor
- Pull out draws for cup holders and remote controls
- Wireless headphones (transmitter and three sets of headphones)

Remote control storage
Just need to get the rest of the interior up to scratch now.
All in all I am happy, with only a few things that I would do differently next time...
Cheers
