Population Density

This TSB is located in the Bowen Hills area close to the city. The intention of my design is to create an artwork that generates the interest of passers by. My design creates an impossibly small brick house and invites the passer to ask the questions;-
Where does the door lead? Who are the eyes in window?
What is the letter in the mailbox?
In a time where population density and expanding urban population is an issue, the design jokingly asks how small a dwelling can be, by creating an impossibly small house in an inhospitable location.
The design turns the box into something resembling a small brick structure with plants growing along the walls.
