Hopefully those ideas will not result to any future crowd or traffic or perhaps a distractions to some by-passers. And the allotted space of the patio building should not block any possible walkway. Also good idea if they uses patio awnings, PVC umbrella or a sun sail as their roof just like the samples from http://coastwideshadesails.com.au/shade-sails-products/waterproof-shade-sails/, as this is not so hard to install and no more digging up for concreting patio post.
