This is my school's assembly area : The place is generally used for the assembly and various other things. But the problem is that it receives a lot of sunlight and it is difficult to use it during the later part of the day. So, I would like something like a roof, which doesn't entirely block out sunlight but makes the place a little more comfortable. One thing I have thought of is installing small nets or rods and then growing creepers on it which would act as a roof. But I am unsure whether this is practical. P.S. The solution must be cheap and if possible eco-friendly.
