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

**Renovation and Expansion 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 carry out structural expansion to meet today's pedagogical, functional and energy requirements. A holistic approach will be pursued, combining refurbishment, expansion and energy efficiency 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 modernised:

- Energy renovation (insulation, windows, building services)

- Barrier-free access (except to the attic)

- Optimisation of the room structure

- Modernisation of the 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 area (A = 74 m²)

- New teachers' room (A = 49.86 m²)

- Storage, tea kitchen, new WC facilities

- Corridor and cloakroom areas

**First Floor (FF)**

- Extension of Classroom 3 (A = 84 m²)

- Extension of Classroom 4 (A = 73 m²)

- New differentiation room (A = 45 m²)

- School library (A = 27 m²)

- New staircase and optimised traffic areas

**Attic (A)**

- Creation of a new presentation and lounge area (A = 72 m²)

- Gallery (A = 13.5 m²)

- Adaptation of the roof structure incl. new dormer

**Basement (B)**

- New multi-purpose room (A = 72.78 m²)

- Canteen serving and preparation area

- Staff room, plant rooms, cellar areas

- Large terrace (A = 83 m²)

**3. Functional and Pedagogical Improvements**

The renovation and expansion of the school building will create a modern learning environment with:

- larger, flexible classrooms

- additional differentiation and group rooms

- a school library

- a multi-functional room for events

- improved teachers' work areas

- optimised play areas (indoor and outdoor)

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

**4. Cost-Effectiveness and Funding**

The planning deliberately focuses on building on the existing structure to reduce costs and utilise 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, outdoor facilities, equipment: approx. 3.8 million €

**5. Interim Solution During Construction**

For the construction phase, the school operation must be relocated. A temporary solution with containers is planned.

**6. Conclusion**

The project "Renovation and Expansion of Züttlingen Primary School" represents a comprehensive modernisation that creates a significant added value both pedagogically and structurally. The combination of renovation and expansion enables a sustainable, economically viable and fundable solution that strengthens the school in the long term and keeps the Züttlingen location attractive.
