Where are patios located on Middle Eastern houses?

Les explains that in the Middle East economy, most of the better homes have their patio on the housetop rather than outside the back door. He pictures these as retired people who have time to spend up on their housetop patio. Jesus addressed such people in a very segmented society, telling them not to come down to take anything out of the house, meaning they must be ready to go. The context also contrasts other groups, like workers in the field who should not return home even for clothes, and mothers with little ones, showing the urgency of flight.
