Neighborhoods of standardized precast panel houses form a significant part of the housing estate in the Czech Republic. As the comfort requirements have evolved since their construction, the buildings often need to be refurbished to suit the needs of a current user. Extending the loggias or balconies is becoming a rather popular modification. Besides improving the functionality of the apartment layout and helping enliven the outdoor environment of the neighborhood by drawing the inhabitants outside, the extension can also help improve the indoor environment of the apartments, as it decreases the overheating in summer.
