In terms of population density, London is one of the least crowded major cities in the world---four times fewer people per square kilometer than Paris, for example, six times fewer than New York and eight times fewer than Cairo. But the fact remains that the city’s population is growing at a rapid rate, and horizontal expansion into the surrounding areas is eating up increasingly important agricultural land, as well as worsening all the transport problems that come with urban growth.
Popular Architecture would propose a radically different solution. The proposal is to go upwards, with vertical towers of considerable size, each representing an entire new town, by the time it’s completed. Each tower would be 1500 meters high. Beyond mere accommodation, each tower would function as an entire town unit, with its own schools, hospitals, parks and gardens, sports faculties, business areas and community spaces. The population density of such a tower could help lower the individual energy requirements of each inhabitant, reducing the ecological impact of the population as a whole.
The village towers are considered as hollow tubes, with large holes to allow light and air though the entire construction. Occasional floor discs spread throughout the height of the building will give inhabitants large central areas in the middle of the tube to use as gathering spaces.
While the building itself is unlikely ever to be seriously considered for construction---imagine the number of elevators it would need, let alone the safety implications of open areas at such heights and with such wind exposure---the concept can serve as conversation-starter for urban planners looking to face the challenges of the current and coming countries.

A.build new satellite towns

C.design less crowded cities
D.accommodate more inhabitants
