A useful decision starts with the existing building, then tests both routes against the same brief.
Assess the existing building
A useful decision starts with the structure, building services, envelope, access, condition and intended use of the asset. A technical review identifies what can be retained, upgraded or changed.
Test both options against the same brief
Refurbishment may face restrictions arising from existing layouts, services or structural systems. A new-build project faces different planning and site requirements. Compare each route against consistent functional requirements.
Make delivery constraints visible
Useful measures include the percentage of constraints resolved, outstanding approvals, milestone readiness and estimated delivery duration. Occupied buildings also call for careful phasing to limit operational disruption.
Define how success will be inspected
First-pass inspection results, commissioning readiness and defect closure at handover give the team and owner objective quality measures. Operational suitability and ease of maintenance matter beyond the appearance of finished spaces.
Make the decision actionable
A concise options appraisal should define the relevant constraints, programme, risks and measurable acceptance criteria. Once agreed, these become part of the Construction brief.
