A neighbourhood can be thought of in a couple of ways. First as a planner of cities, divided on socio-political lines, by type of housing or land use. Objective and mapped.
A neighbourhood is also understood by it's inhabitants in a different way, and is defined by direct experience of place. Your neighbourhood is where you walk the dog, buy your bread and milk.It's a common place place which nevertheless is emotionally imprinted, It's intimate enough to be known by all the senses, and in that way is an extension of your home. it's boundaries change depending on who you are and how you use the space. It may even be that the pavement over there, isn't in your neighbourhood if you never walk that way.
