• Area per Unit: Each team changing room unit will comprise a changing area of $15 \text{ m}^2$ and a private shower/toilet facility of $9 \text{ m}^2$, totaling $24 \text{ m}^2$ per unit.
• Total Area: The total area allocated for the four team changing rooms will be $4 \times 24 \text{ m}^2 = 96 \text{ m}^2$.
• Private Facilities (9 m² each):
  • Two of the changing rooms will each have two separate toilets (each with its own door and enclosure), two separate showers (each with its own door and enclosure), and one wash basin.
  • The other two changing rooms will each have one toilet (with its own door and enclosure), two separate showers (each with its own door and enclosure), one wall-mounted urinal, and one wash basin.
