Summary
Machine-generated summaryThe Centre for Hearing and Speech Zurich (ZGSZ) has been running a temporary school operation since the 2025/2026 school year for children with hearing and/or speech impairments and autism spectrum disorder, located in the ground floor and half of the first upper floor of a 1976 pavilion at Roemerweg 37 in Embrach. The previously unused eastern half of the first upper floor and the entire second upper floor are to be converted into temporary residential group facilities with a total of 14 places. The existing structure of the previous user is well suited to the needs of the residential groups with only minor adaptations. The works fall under section BKP230 Electrical installations, and implementation takes place during school holidays.
