As part of a PPP pro­ject, the BBS I and BBS III school exten­sion in Alten­ha­gen was suc­cessfully com­ple­ted on time for the dis­trict of Celle. AUGUST REINERS Bau­un­ter­neh­mung GmbH, as PPP con­tract part­ner, was respon­si­ble for the plan­ning, turn­key con­s­truc­tion, inte­rim con­s­truc­tion finan­cing and main­ten­ance services. 

In addi­tion to the con­s­truc­tion of the school buil­ding, the con­tract also included the con­s­truc­tion of sports faci­li­ties and out­door areas. The roof of the buil­ding has a PV sys­tem. The pro­ject has DGNB and QNG Sil­ver certification. 

The new exten­sion to the Alten­ha­gen school com­plex was pla­ced cen­trally in the area of appli­ca­tion as an inde­pen­dent two-storey buil­ding block to com­ple­tely frame the schoo­ly­ard area. An appro­priate distance from the exis­ting buil­ding allows direct access to the sports areas in the sou­the­ast wit­hout sepa­ra­ting them from the new cam­pus center. 

The roofs of the sur­roun­ding buil­dings, which are cha­rac­te­ristic of the area, were con­tin­ued and reinter­pre­ted on the exten­sion. The solid gable ends of the newly desi­gned pit­ched roofs give the buil­ding the neces­sary degree of indi­vi­dual cha­rac­ter wit­hout domi­na­ting the exis­ting buildings. 

The mul­ti­func­tional hall, which is gene­rously lit via an inner cour­ty­ard and sky­lights, acts as the cen­ter and heart of the buil­ding bet­ween the two main ent­ran­ces, with an open stair­case as the main access to the second floor.
The majo­rity of the class­rooms are loca­ted there, which are acces­sed via a two-floor sys­tem along the hall, the inner cour­ty­ard and side room zones. Along the cor­ri­dors, widenings with inte­gra­ted sea­ting niches serve to extend modern tea­ching with dif­fe­ren­tia­ted and spon­ta­neous small groups bey­ond the classrooms.
