My DESIGN solution!!

I thought of many options like cemented benches, stools made from barks of trees, joining bricks together and making a stool out of it, piling up the tyres and making of stools, wodden stools and benches but at the end i realize that i was supposed to choose something which was very economical to him and something which he can keep aside the road when he shut his stall. Cemented benches and bricks would cost him more so this idea was dropped by me and then i jumped to the idea of using barks of trees to make the stools and tables but then i was told by my teacher that it is an direct example of deforestation so again i dropped this idea too. Then, i thought of the rough  big stones which are easily available nearby the roadside and in the parks and gardens. These stones can be placed anywhere and also he can keep them aside when he leaves. Then finally i got an approval for this idea of using big stones to sit giving them a shape of stools and a table made up of stones on which the food material can be placed.
