Project Details

The Irena-Sendler-School (ISS) is a district school offering senior classes that will allow for qualifications to enter university. The property has a total area of 42.000m2.The old one to two-story buildings were completed in the 1950s and 60s. In the 1970s, a four-story main building and additional buildings were added. Recently, a new three-bay gym and outside facilities had been constructed. The real estate is in bad condition and is currently under construction to become a full-day school. The overall bad condition of the building and the dated facilities led to extensive remodeling plans. The new constructions are planned as new buildings about the same size that are going to be erected on almost square-shaped footprints. They are built in the center and connected by a joint schoolyard. The south-eastern three-bay gym and the other three buildings add up to an urban ensemble. Within the building, rooms are grouped in compartments; traditional corridors are not mandatory anymore. Every grade gets greater open areas that are ready to be developed and serve as various useful areas. The remodeling and renovation process of the school is going to be realized in three construction phases during day-to-day business.

Building A
Building A houses class rooms, rooms for teachers, art rooms, staff room for teachers, and a big central media room with a library/media center where students are ably to study.

Building B
Building B houses central facilities like offices, a cafeteria including a kitchen, an assembly hall, an integrated gym (including necessary storage and locker rooms), science rooms, rooms for music and theater, a kitchen for teaching, and usual class rooms.

New Buildings are going to be easily accessible to the public according to requirements of the DIN 18040-1 standard (Part I: public accessibility of buildings). Both buildings get accessible elevators with which every level can be reached (except for the basement housing technical installation).
