Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
Photos of the Tanikawa House, designed by architect Kazuo Shinohara.
Built in 1974, this summer house materializes the act of covering a piece of earth, making it an inhabitation only by means of a roof protecting the dirt soil of the ground. The house lies on a slope in a middle of a wood and grows through an exposed timber frame structure which supports a large pitched roof. Under the roof, a minimal section of the house located on a side hosts some specific living functions concentrated on two floors: a bathroom, a kitchen, a bedroom and a staircase. This section lies in parallel to the main “earth room” (or “summer room”) and overlooks it.
