Most of the time the solutions provided are not produced in the region where the disaster occurred.As a consequence, much discussion has been centered on the question whether temporary housing is really needed, due to longer reconstruction processes, or rather an overspending that represents an important consumption of resources that are crucial for permanent reconstruction (Steinberg, 2007).Besides the costs associated to the units, there are the expenses with the whole infrastructures needed to make temporary settlements functional (roads, water, sewerage, electricity, etc.).According to UNDRO (1982), a temporary house unit can cost more than a permanent one and some authors refer that it may be three times more expensive (Hadafi & Fallahi, 2010).

Most of the time the solutions provided are not produced in the region where the disaster
occurred. Importing and transporting the units or materials required to re-house all the victims
may involve extremely high costs. According to UNDRO (1982), a temporary house unit can
cost more than a permanent one and some authors refer that it may be three times more
expensive (Hadafi & Fallahi, 2010). Besides the costs associated to the units, there are the
expenses with the whole infrastructures needed to make temporary settlements functional
(roads, water, sewerage, electricity, etc.). This way, temporary housing becomes a very
expensive kind of solution in relation to its lifespan because it implies huge investments in units
that will only be used during a short period of time (Johnson, 2008). As a consequence, much
discussion has been centered on the question whether temporary housing is really needed, due to
longer reconstruction processes, or rather an overspending that represents an important
consumption of resources that are crucial for permanent reconstruction (Steinberg, 2007). As a
result, the works of permanent reconstruction may be delayed and people have to stay in
temporary units longer than it was planned. Since those temporary settlements are not planned
for long periods, some social problems can appear (Johnson, 2007b). Beyond the questions
about costs and their effects on the overall reconstruction, importing the units means long delays
in the process of resettlement due to the time needed to produce, transport and place the units on
the site.
