Room Configuration

Standard rooms use the IWPS 3.67:1 ratio to auto-calculate quantities. Fixed-count rooms (training rooms, work cafés, multipurpose halls) are set by the designer based on client brief and are not ratio-driven.

Indicative space programming for preliminary planning. Final numbers subject to detailed brief, local authority approvals, and architectural design.
