To accommodate all the laboratories and support areas comfortably, I recommend between **1 200 and 1 500 m²**. Below is a suggested allocation:

| Area | Module | Area (m²) |
|---|---|---:|
| Additive manufacturing | 3D printing | 80 |
| Cold metalworking | Cold metals | 120 |
| Hot metalworking | Hot metals | 80 |
| Laser cutting | Laser cutting | 50 |
| CNC/router & mill | CNC | 80 |
| Electronics | Electronics | 70 |
| Assembly & testing | Lab benches & assembly | 60 |
| Plastics | Plastics | 50 |
| Finishing | Finishing | 60 |
| Testing | Testing (including 3D scanner) | 60 |
| Textiles | Textiles | 30 |
| Wet lab | Work involving fluids | 40 |
| Woodworking | Woodworking | 100 |
| Software & CAD | Software stations | 40 |
| **Technical-area subtotal** | | 920 |
| Circulation and safety | Corridors, exits and perimeter clearances (≈25%) | 230 |
| Storage | Raw materials and parts | 100 |
| Office / meeting room | Coordination and training | 80 |
| Reception / support | Reception, kitchenette, toilets | 70 |
| **Approximate total** | | **1 400** |

**Rationale**
- Each laboratory includes space for its machines, support workbenches and manoeuvring.
- Around 25% is added for safe circulation, signage and separation zones.
- Support areas are included: storage, offices, kitchenette and toilets.

This layout provides an efficient space for self-taught makers and students, without restricting workflow or overloading the machines.
