A lower total is not automatically better value. Compare the work, materials and finishing included in each proposal first.
Compare the complete intervention
Price the transition as a complete item: frame, flooring repairs, external junction and storage. Separate prices can conceal missing work between these elements.
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
Draw a section with internal floor, threshold, outside level and drainage. Add a plan showing door movement, shoe storage and everyday access.
Which trade-off matters?
A more generous back-door zone may require a smaller kitchen arrangement. Compare the clear space and storage each option provides before fixing the external wall.
Questions for your own property
- Is the finish level equivalent?
- What is excluded?
- How are changes recorded?
