Pertouli is located in the county of Trikala, at altitude 1150 m. It is 50 km away from the capital of the county. It is surrounded by the verdant mountains with firs of Pindos. The village is built on the east side along the highway of Trikala - Arta in 3-4 levels (built in an amphitheatrical way) defined by parallel streets. It keeps, basically, the regional style, which is the one from Epirus, ie stone structures. Nowadays (today) it has about 250 residents.

The study area is located at the borders of Pertouli, at the right side of the highway. They are 33 acres of public land and the lower point has altitude 1151 m, whereas the higher has altitude 1177 m. The area is surrounded by tall firs, while a creek runs through part of the region. The pine forest is a model forest ecosystem and it attracts scholars, scientists and naturists throughout the year. So, in this area is recommended the construction of an Environmental Centre.

The purpose (aim) of the C.E.E. of Pertouli is the support of the institution of Environmental Education in the wider region of Thessaly and the rest of Greece by: Educational Programs for students of primary, secondary and higher education and training seminars of E.E. for teachers during one or more days. Furthermore, organized student groups and individuals sensitized to the environment, can visit the area, to be guided on-facilities and get information on programs made there and take part in them.

The Environmental Centre consists of two buildings, which are linked (connected), by a glass and have a total area 2040 sm. We can characterize the first building as the educational part of the centre, while the second as the entertaining. These buildings include a reception, an amphitheater, classrooms, a biology – physical chemistry laboratory, guest rooms (hostels), spaces for administrative purposes, auxiliary spaces, café restaurant, gallery, computer room, library – reading room, free labor room (workshop) laboratory – kitchen, warehouse, toilets and locker rooms.

In the outer space there is parking space and also educational garden with a lake that contains aquatic plants.
For the construction of the building they were used materials that go with the  regional style of the area. The outer walls are dressed with stone, the yards are paved, while in the interior of the building there are wooden floors.

Finally, important piece of the building are its green roofs, which provide important advantages, as far as temperature is concerned, but also for the aesthetics of the environmental centre.
