Typical programme durations for commercial construction vary based on project size and complexity. Small projects might take 6-12 months, while larger ones can stretch from 12 months to a few years. Always factor in design, approvals, and potential delays.

Key points

  • Small projects: 6-12 months
  • Medium projects: 12-24 months
  • Large projects: 2+ years
