Renovation or New Construction: How to Decide

Renovation or New Construction: How to Decide

The right choice depends on the condition and adaptability of the existing building, planning constraints, budget and project objectives.

Assess what can be retained

Structure, envelope, services and spatial potential should be evaluated before assuming that demolition or preservation is preferable.

Compare equivalent scopes

Include surveys, temporary works, approvals, waste, energy performance and future maintenance in both scenarios.

Consider uncertainty

Renovation carries concealed-condition risk; new construction carries ground, approval and full-delivery risk. Both need contingencies.

Practical checklist

• Commission an independent condition survey
• Compare whole-project costs, not headline rates
• Confirm planning constraints with the relevant authorities

A documented feasibility study is more reliable than choosing on appearance or initial price alone.
