“KŌSAKU” is a DIY kit which you assemble the parts as thinking of its structure and design referring to the illustration. 
You can make either one of these products depending on the combination of woods —
a bird house or a little stool. 
It can be much more enjoyable kit if you painted it or customized your own product with some parts left over. 

*This project is based on a brushed-up version of the “Bento Kit” which was developed for “Art Village for Children,” a project supporting children living in areas affected by the 2011 earthquake.
