A lower total is not automatically better value. Compare the work, materials and finishing included in each proposal first.
Compare the complete intervention
Include temporary kitchen facilities, protection and any extra moves. A programme with more phases may require more setup and clearing work than continuous construction.
Align the scope
Use the same headings for preparation, demolition, structure, installations and finishes. Mark missing items and distinguish fixed prices from provisional allowances.
Read the assumptions
Ask what provisional sums are based on and how final choices are reconciled. A low allowance lowers the quoted total without necessarily reducing the eventual cost.
What the drawing needs to explain
Create a phase plan showing work zones, usable rooms and bathroom access. Identify temporarily unavailable facilities and their replacements.
Which trade-off matters?
A short intensive programme and longer phased work have different effects. Compare temporary facilities, access and quiet periods as well as total duration.
A situation to test your plan against
A larger home offers little help if every daily function stops during renovation. Begin with a weekly overview of cooking, washing, working and sleeping. Use it to discuss construction phases.
Questions for your own property
- Is the finish level equivalent?
- What is excluded?
- How are changes recorded?
