A lower total is not automatically better value. Compare the work, materials and finishing included in each proposal first.
Compare the complete intervention
Compare purchase and recurring maintenance costs. Ask about preparation, fixings and access; the material price per square metre alone gives insufficient guidance.
Align the scope
Use the same headings for preparation, demolition, structure, installations and finishes. Mark missing items and distinguish fixed prices from provisional allowances.
What the drawing needs to explain
Detail the lower edge and the junction with another material. Show where water can drain and how an element can be replaced without opening the entire finish.
Which trade-off matters?
Uniform colour and low maintenance are not automatically the same choice. Compare a coated surface with a material allowed to change visibly, including access for future maintenance.
Questions for your own property
- Is the finish level equivalent?
- What is excluded?
- How are changes recorded?
Illustrative design situations, not evidence of completed work. Assess decisions against the actual property.
