The public school of Sarriguren (Valle de Egüés, Navarra) has a constructed area of ​​approximately 4,795 sqm. Formally, the proposal is shaped by two differentiated volumes: The main volume, located along the north road, is developed on two levels and houses common uses and those corresponding to Primary Education. In parallel, towards the canal, another lower volume, that contains the uses related to the program of Early Childhood Education, is created 

The center has a total of 18 primary classrooms, 9 children's classrooms, three language classrooms, six classrooms, a multipurpose room, a library, a music classroom, a computer room, a psychomotor classroom, gym, dining room, kitchen, teachers' rooms and administrative areas.

The building is conceived so that all the classrooms can be concentrated in a single plant. In the case of Primary Education classrooms, the three educational lines are grouped on the first floor of the main volume, while in the case of Early Childhood Education, they occupy the lowest floor of the smallest volume.

This two-piece building layout allows for greater flexibility in use, better adaptation to the terrain, and naturally integrates the free areas that structure the exterior expansion spaces.

The patios and recreation areas are naturally generated between the two built pieces. The courtyard for Primary students occupies the open area between the two volumes, while the Children's playground opens to the south of the block that houses the Early Childhood Education program. The sports area has been arranged to the south of the main building and parallel to the building  for children. In this way, it is directly related to the building through the glazed area to the south of the ground floor and inside the patio destined to primary.
