The building materials are bricks, tiles, timber, skeleton iron, stone, cement and mortar. Each of these materials must be manufactured or cut out from raw materials. So kilns for the manufacture of tiles and bricks must be put up. Mills for timbers must be established, also factories for skeleton irons. Quarries must be opened and factories for cement and mortar must be started. All these establishments must be put up at suitable districts where materials and markets are near one another. All should be under one central control so as to regulate the output of each of these materials in proportion to the demand. After the materials are ready they must be transported to the places where they are wanted by special bottoms on waterways, and by special cars on railways so as to reduce the cost as low as possible. For this purpose special boats and cars must be built by the shipbuilding department and the car factory. b. The Construction of Houses The houses to be built in China will comprise public buildings and private residences. As the public buildings are to be built with public funds for public uses which will not be a profitable undertaking, a special Government Department should therefore be created to take charge. The houses that are to be built under this International Development Scheme will be private residences only with the object to provide cheap houses for the people, as well as to make profit for this International concern. The houses will be built on standardized types. In cities and towns the houses should be constructed on two lines: the single family and the group family houses. The former should again be sub-divided into eight-roomed, ten-roomed and twelve-roomed houses, and the latter into ten-family, hundred-family and thousand-family houses, with four or six rooms for each family. In the country districts the houses should be classified according to the occupation of the people, and special annexes such as barns and dairies should be provided for the farmers. All houses should be designed and built according to the needs and comfort of man; so a special architectural department should be established to study the habits, occupations and needs of different people and make improvements from time to time. The construction should be performed as much as possible by labor-saving machinery so as to accelerate work and save expenses. c. The Manufacturing of Furniture As all houses in China should be remodelled all furniture should be replaced by up-to-date ones, which are made for the comforts and needs of man. Furniture of the following kinds should be manufactured: the library, the parlor, the bedroom, the kitchen, the bathroom and the toilet. Each kind should be manufactured in a special factory under the management of the International Development Organization. d. The Supply of Household Utilities
