Scarcity of land, which is too expensive in any case, has given birth to concept of the high rise construction which was not seen so a couple of centuries ago when big constructed buildings were spread over a large area from east to west and south to north. The horizontal buildings, therefore, as compared to vertical buildings, provide maximum accommodation space within the shortest possible area and therefore under the given circumstances it is advantageous to go for sky scrapers instead. However, height necessitates that there must be elevators and escalators to cover the distance from the ground to the level one wishes to reach simply because it will be next to impossible for human beings to reach the top if the structure is a high rise building.
