The decision behind the detail
Separate condition-related work, functional improvements and decorative additions. Review the cost of the complete essential scope before distributing the budget across upgrades.
A useful checklist
- Rank each scope item
- Identify dependencies
- Keep a contingency
Bring it into the project brief
Ask for optional items to be clear in the proposal. That makes adjustments easier than reducing every allowance without a plan.
For the related scope, see room-by-room renovations. Keep the relevant measurements, selections and open questions together before requesting a written quote.
