Germany – Engineering design services for mechanical and electrical installations for buildings – Sanierung und Erweiterung Grundschule Züttlingen

**Renovation and Extension of Züttlingen Primary School Based on Feasibility Study, Plans, Floor Plans and Details Office Huber, Billigheim**

**1. Initial Situation and Objectives**

The primary school in the Möckmühl district of Züttlingen is located in an existing building at Jahnstraße 5, directly adjacent to the town hall and the church. The building has functional, spatial and energy deficiencies that make comprehensive modernisation necessary. The project's aim is to renovate the existing building and extend it to meet today's pedagogical, functional and energy requirements. A holistic approach will be pursued, combining renovation, extension and energy efficiency in one project.
