Before you set the budget
Three decisions that protect your renovation budget
Define the same scope
Write down demolition, retained items, service moves, finishes, approvals and exclusions so every comparison covers the same work.
Separate allowances from fixed prices
Track provisional sums and prime-cost items separately. These are common sources of budget movement after work starts.
Hold a risk reserve
Keep the difference between the central and high estimate visible until access, structure and concealed conditions are confirmed.
