Lost spaces in urban area:
A few days ago when I was studying about a highway in Cape town, I noticed that spaces around these constructions are mostly empty and remained unused. I found some book and article to know about the causes of this issue.According to Moghaddam and Yazdipour ( 2014) in cities there are some areas that have been vacant or have not been used for along time.  They do not attract people and they are not connected to other areas around them. Areas around and under high ways, areas around rail road lines, water fronts ,spaces between buildings and industrial complexes  are examples of these spaces. To fill these areas and give them vitality, first it is important to recognize them.After that by providing suitable lighting and furniture and green spaces they could be fill by people.There are criteria like security and accessibility that should be improved.Communication by people in these areas could bring sense of belonging after a while that is an important criteria to make it alive.
