Quick Answer

Renovation makes sense when the existing layout and structure largely work and only finishes or specific systems need updating; a new fit-out (starting from shell-and-core) makes sense when layout, MEP capacity, or structural changes are extensive enough that working around existing elements adds more cost than it saves.

This decision affects budget, timeline and disruption more than almost any other early project choice.

When Renovation Makes Sense

If the existing layout suits your needs and MEP systems have adequate capacity, renovating — updating finishes, refreshing specific rooms, replacing aging systems — is typically faster and less expensive than starting over.

When a New Fit-Out Makes Sense

If you're changing the fundamental layout, need significantly more MEP capacity than exists, or the space has been vacant and stripped to shell-and-core, planning a new fit-out from scratch avoids the inefficiency of working around outdated infrastructure.

The Cost Crossover Point

As a rough guide, if more than 60-70% of a space's finishes and systems need replacement, a full fit-out often ends up costing similar to or less than a piecemeal renovation, since demolition and rework overhead is avoided.

Getting an Honest Assessment

A site survey that evaluates existing MEP capacity and structural condition — not just visible finishes — is the only reliable way to make this decision with real numbers rather than guesswork.

FAQ

Usually, but not always — if most finishes and systems need replacement anyway, a full fit-out can end up costing similar or less due to avoided rework.
