On the Moon, unique situations exist for observing the infrared parts of the spectrum. In the Polar areas this possibility is extremely good because of the Permanently shadowed areas which belong to the coldest places in our solar system which means that the surrounding infrared background radiation which disturbs the measurements is very low. The South Pole offers the best possibility to really build such an observatory. From research done a few years ago by several sources from the data of the Clementine mission it appears that a unique combination exists at the South Pole. Permanent Shadowed areas located within a few kilometres of a small area that is almost permanently lit by the sun. By placing a communication relay on one of the Lunar Mountains it is also possible to have direct communications with this place which can not be seen directly from Earth. At the same time it is one of the most interesting parts of the Moon from a geology point of view because it is located inside the largest basin on the moon (South Pole - Aitken Basin), as well as the possibility that ice may exist there. This results in the location choice for Shackleton Crater for the placement and construction of the Lunar South Pole Infrared Telescope together with a communication relay station in the form of a Lander at Malapert Mountain a dn another communication relay and energy supply station in the form of a Lander at the Peak of Eternal Light. In this paper a description will be given of the design of the telescope and the scenario that was chosen to construct this telescope. The Location and type of mission requires a design that is scenario and environment driven. The Scenario determines way of construction (on earth, in orbit, on moon), timeline and maximum masses, sizes and volume of the payloads to be delivered to the lunar surface. The location on the Moon means that no infrastructure or resources are available without processing except for the lunar regolith itself. The environment determines the choices of materials and details (dust, ground situation) The local terrain determines communication, energy-supply, light, resources, location, foundation and the way of construction. It appears that it is possible to built a telescope with the same capabilities as the Next Generation Space Telescope on the Lunar South Pole except for the sky coverage that will be limited by the location and orientation. The telescope has a diameter of 8 meters and is an altitude-azimuth design. The bearings will be made of super conducting magnets that use flux pinning to stabilise themselves while at the same time they are very energy-efficient. The foundation will be put together and dug in-situ using robots and telepresence together with virtual reality and local laser rangefinders. If all goes well the telescope would have settlements no greater than 0,03 mm during operation. When the telescope is built, an infrastructure has been created for energy supply and the relaying of communications that can be used in subsequent missions. The total mission is achieved by launching 3 ariane's 5 in the 2006 configuration that can launch 20.000 kg in GTO.
