It is the supreme principle of all activities of the WPK to steadily improve the standard of people's living.

At the first Cabinet meeting after the 1950-1953 Fatherland Liberation War, President Kim Il Sung raised the issue of large-scale construction of dwelling houses as one of its agenda items and took measures to furnish a huge amount of state funds to the construction.

When visiting an apartment in January, Juche 47 (1958), the President stressed the need to install the underfloor heating system of Korean style in all apartments.

Early in May 1973, he looked round a modern village house and called for building such house for all farmers in the country at an early date.

Under the wise guidance of leader Kim Jong Il, Rakwon, Changgwang, Munsu, Kwangbok and Thongil streets took their shapes in Pyongyang in the 1970s, 1980s, and 1990s.

True to the noble intention of Kim Il Sung and Kim Jong Il, supreme leader Kim Jong Un personally initiated the construction of apartment houses for educators and scientists and settled all problems arising in the project.

His tireless devotion for people is closely associated with the completion of modern apartment houses for educators of Kim Il Sung University and Kim Chaek University of Technology, Wisong Scientists Dwelling District, Mirae Scientists Street, dwelling houses in the Jangchon Vegetable Co-op Farm and Rason City, etc.
