Alloy model of tenement building

Tonglou, which first appeared in Hong Kong in the mid-to-late 19th century, has no elevators, a rooftop, and a two-foot-wide iron arcade. It was only two to three stories high at first, and later developed to up to eight stories high. It is built with green bricks. In the later period, concrete replaced bricks and became the main building material of tenement buildings. Most of the tenement buildings used the underground floor for shops and the upper floors for residential use. Before the Hong Kong government built a large number of public housing, most Hong Kong people They are residents of old-style "tenement buildings". Due to the high demand for housing in Hong Kong and the preciousness of land, real estate developers have targeted tenement buildings for land resumption and reconstruction, and built more high-rise residential and commercial buildings. Therefore, tenement buildings have now become rare to buy.
