Summary
Machine-generated summaryThe town of Sontra intends to convert the former Regenbogenschule at the south-eastern edge of its old town into a daycare centre for four groups. The two-storey south wing will house four group rooms, two for children under three and two for older children, while the attic will become a multifunctional hall for cultural and community events with up to 200 people. The existing building will be comprehensively renovated and partly rebuilt; the west wing will be partly dismantled for functional and fire safety separation. The project forms part of the urban development programme 'Lebendige Zentren'. Procured services cover technical building equipment design, service phases 1 to 8, fee zone II, with utility design planning. Planning starts April 2026, completion July 2028.
