The research-based starting point is one enclosed pod per 10–15 employees for knowledge-intensive teams, across a mix of single-person and 2–4 person models. For teams with high call volume, confidential conversation requirements, or deep-focus individual work, one pod per 8–10 employees is more appropriate. The most reliable indicator of capacity needs is pod utilisation data: when average utilisation exceeds 70% during peak hours, additional capacity is indicated. HIGHKA’s five-model range allows capacity to be added in precise increments matching actual demand.
