16 Month House explores the possibility of using an existing infrastructure: billboards and using this structure as housing. Because this infrastructure is made to make money through advertising, living in such a structure the occupant can have two "tenants" that pay for advertising space (up to $15,000/month depending on location).

Extrapolating typical construction costs, utilities, and up keep, given a $15,000 advertising income every month the occupant would return their investment in the structure in 16 months.
