This fence is made from stripped coconut leaf-fronds. Not sure what it was keeping in – or out – there were only two sides…

 
This construction was on a tiny island which appeared to only have vertical cliff faces for ‘shores’. Apparently the ‘birds-nest collectors’ only come after the birds have nested and moved on, but security protects the ten-year leases of this site all year round.
 
 
This ‘pier’ was constructed from lego-like connections between pieces that resembled – and felt like –  airfilled, plastic bottles. Even the ‘safety’ rails were constructed from the same plastic with single rope-link.

How you define ‘under construction’ or ‘temporary’? When does something become ‘constructed’ or ‘permanent’? Or dare one say, ‘finished’? Is anything ever finished?
