LowLine is the world's first underground park in the following photographs. It was made using underground trolley terminal which became the abolition station, but you can see that the light necessary for plant photosynthesis is hit.


This is not LED light, genuine sunlight. James Ramsey, the creator of LowLine, invented the technique called "remote skylight" to transmit the sunlight from the collector installed on the ground to the underground, diffuse it with the aluminum canopy on the ceiling, It is illuminating.


The structure that the park has a gravel path between two small hills covered with ferns and flowers. Plants such as Philodendron, Chitoseran, Murasaki Yukusa, Nettle, Saruganase Monoduki are growing abundantly. Although it has not completed yet, the area of ​​the site is about 5570 square meters (about 1660 tsubo), and if completed, a vast green space will appear in the basement of New York.


It is already open to the general public, and a tour to see inside is also held.


A collector on the ground is like this. It seems that the collected sunlight will be 30 times as bright as usual, but since the sunlight transmitted to the underground through the pipe is diffused by the aluminum canopy stretched over the ceiling, there is no danger of the plant burning And that. The spider may make a nest on the mirror of the condenser, and it seems that it is a kind of trouble that the light collecting efficiency drops when left unattended.


Ramsey, once NASA Saturn probeCassiniHe is also a member who is a CEO of RAAD design company RAW. Also on LowLine's team are Mr. Dan Barasch, who worked as a company strategist at Google, with excellent talent gathered.


According to the development team of LowLine, it is estimated that the development cost of the underground park is estimated to be between 44 million and 77 million dollars (about 5.3 billion yen to about 9.2 billion yen), and the maintenance cost ranges from 2 million to 4 million dollars ( About 240 million yen to 480 million yen) is considered necessary. In addition, the team is planning to operate the park in New York City and the public transport operator that owns the waste stationMTAAlthough it is in negotiations with you, it seems that it is a difficult point that it does not fit the definition of a general "park" because it can not do barbecue and baseball. Since it is possible to receive funds from the city if it is accepted as a public space, it is said that it can be defined as a public space such as "botanical garden".

LowLine is still attracting attention, such as being awarded "next generation park" in a newspaper for architects, but it is still in need of clearing many problems before putting it into practical use. The LowLine team will fully develop the underground park from 2016 and aim for completion by 2020.
