The aim of this paper is to provide an overview of the origin of the passive house, the community who came up with the idea, the first examples of this type of building, the characteristics of passive houses that make them so different from conventional houses, and to describe a passive house construction in the United Kingdom by giving examples and descriptions of the selected houses. For some countries, building of passive houses is still in its beginnings, therefore it is necessary to deal with this matter, to get to know it better and to emphasize its significance in order to easily understand, but also possibly motivate passive building. There is a need to think differently when it comes to construction. In the present, we are faced with enormous energy consumption, even in households, which also includes (either directly or indirectly) burning of fossil fuels. It is evident that the damage fossil fuels are causing to our environment is irrepairable. But there is still time to conserve what we have left and also, other sources of energy are needed. Apart from the fact that a passive house gives some very effective solutions, it also helps its owner reduce a great extent of household expenses. The main feature and also the key of what defines the passive house is its insulation thickness, resulting in no need for cooling/heating. All of the elements (windows, doors, cold bridges, etc.) must be processed and installed properly within the Passive House demand standards. This type of construction should be implemented. People have to look forward to lowering the energy consumption - it brings most benefits. The only concern is primary investment, but it is worth it. Passive houses can even produce energy. One important feature is sun energy storage which can be used when needed. By construction in the proper way, all costs can be greatly reduced.
