A quick glance at Pinterest brings up some intriguing examples of hoarding design:
This isn’t a hoarding however, it is and example of how the “fourth wall” can be broken and allow people to interact and experience advertising in a practical and useful way. The designs here aren’t even complicated at all which represents how simple, smart and straightforward the idea is.
Another feature to play around with is scale, usually unusually sized things create interest and a sense of unfamiliarity. In this example the pencils don’t have an obvious relation to the company which is estate agents but, the people would get “wow-ed” by the installation and then think “hmm, what’s this about?” and look into it a bit more and read the actual content.
Texture is another thing to consider when creating advertising for the development for me as the prospective feel of the place could be ‘translated’ from a mental thing to a physical tangible thing that you can actually feel. Another thing I noticed was the shadow in this photo, shadow can also be played around with for example a large sun dial could be created to arouse interest.
Including something organic is another possibility which allows for a natural visual change over time. Although it is possible to do this anyways just a piece which is changed over time.
I also did some primary research, capturing hoardings around London to see how they do it.
