15. Making the roof trusses

To finish off the store we have created some “A “frames as the structural element of the roof. This then would be placed on to the beams by means of bolts and plugs (or metal ties with concrete nail).  Next we hope to align all the frames by using a ridge beam as shown in the illustration below. Water proofing the roof would be done by using some plastic sheets beneath the battens. Finally the tiles would be made either from recycled plastic bottles or aluminum cans. (This finishing touch is yet to be decided by the students because the resources needs to be collected or gathered by them.)

Hope this will be the final product
