Germany – Load-bearing structure design services – Sanierung und Erweiterung Grundschule Züttlingen

**Renovation and Extension of Züttlingen Primary School Based on Feasibility Study, Plans, Drawings and Information 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 modernization necessary. The project's goal is to renovate the existing building and extend it structurally to meet today's pedagogical, functional, and energy requirements. A holistic approach will be pursued, combining renovation, extension, and energy retrofitting in one project.

**2. Project Scope**

Based on a feasibility study, the following scope has been determined:

**2.1 Renovation of the Existing Building**

The existing primary school will be comprehensively modernized:

- Energy renovation (insulation, windows, building services)

- Barrier-free access (except for the attic)

- Optimization of the room structure

- Modernization of sanitary facilities

- Adaptation to fire protection measures

**2.2 Extension and Supplementary Building (New Construction)**

Based on the feasibility study, the extension will be carried out in several building sections and storeys, creating new or enlarged areas:

**Ground Floor (GF)**

- Extension of Classroom 1 (A = 70 m²)

- Extension of Classroom 2 (A = 73 m²)

- Covered playground (A = 74 m²)

- New teachers' lounge (A = 49.86 m²)

- Material storage, tea kitchen, new toilets

Through the investment, the school site in the Züttlingen district will be made future-proof, sustainable, and pedagogically upgraded.

**4. Economy and Funding**

The planning consciously focuses on building on the existing structure to reduce costs and utilize funding opportunities. As part of the feasibility study, a cost estimate was carried out: The cost estimate according to DIN 276 results in:

Gross construction costs: 3,800,000 €

Total costs excluding land, external facilities, equipment: approx. 3.8 million €

**5. Interim Solution During Construction**
