The purpose of creation and use of transformed individual apartment houses is change of the maintained area of building volume and other technical and economic parameters of the house under influence of changing factors eventually. Distinguish following three basic types of transformed dwelling: with change of external parameters of the house, with change of internal parameters of the house and the combined type. The first type is applied, basically, in case of erection of the house on stages, with use of the subsequent additional attached premises{rooms} and floors. Thus external parameters change - the area of building, этажность, a total area and building volume of the house increases. The second type of houses is used, mainly, within the limits of unchangeable dimensions of the house by adaptation of habitation by means of internal transformed partitions. Thus internal parameters of the house - quantity{amount}, the area and proportions of premises{rooms}, functional zoning and communication{connection} between premises{rooms} are modified only. The area of building, этажность and building volume of the house thus, usually, does not increase. It conducts to creation in the house of so-called universal spaces. The third, combined type of transformed habitation represents a combination of principles of external and internal adaptation.

The transformed habitation has found a wide circulation in the USA, Japan and other foreign countries. In the Russian practice the given kinds of individual habitation yet have not received sufficient application because of complexity of manufacturing and operation of special building designs. However forecasts of scientists confirm perspectivity of use of dynamical and adapting habitation in the future. So, in design offers of many architects and scientists there are many original offers for transformed inhabited cells in usual and extreme conditions.

Depending on a way and character of adaptation distinguish following basic kinds of transformed houses: developing, pneumatic, put forward and cassette.
