Brownfield vs greenfield
What it is
The two routes to adding capacity in any capex-heavy business. Brownfield debottlenecks or expands an existing site, or acquires a running asset; greenfield builds new on fresh land
Brownfield reuses land, utilities, approvals, workforce and customer base, so cost per unit is lower and ramp-up faster. Greenfield carries full land, clearance and construction cost and a multi-year gestation before it earns
Impact on industries
- Cheaper per unit of capacity and fastest to ramp, so most expansion cycles lead with it - added hospital beds fill on an existing clinical team rather than maturing over 3-5 years
- Regulatory easing can enlarge the runway abruptly - NBCS 2026 removed the 45 m hospital height cap, turning owned urban land into expandable capacity
- Brownfield is capacity-limited and priced accordingly: sites are finite, and acquisition multiples rise with sector valuations
- Greenfield is the only route into a new geography but concentrates execution and demand risk - a ~14,500-bed hospital pipeline risks over-supply if demand lags
