Reinforced concrete houses are practically maintenance free and can withstand natural disasters such as fire, tornados, hurricanes and termites. The high construction cost of such houses has made it next to impossible for average income people to own them. Using Rot-Up method of construction high quality reinforced concrete houses can be constructed in a relatively short period of time at an affordable cost. In the construction process of such houses, all the sections comprising the house such as walls, roofs and floors are cast as sandwich type sections and then rotated up to the final positions by means of two 90 degree rotations.
