A clear budget starts with clear scope.
The cost follows from the existing building and the agreed work.

Compare the complete intervention
Separate investigation, necessary repairs and improved access. Identify uncertainties in concealed areas, with an agreed decision point after opening them.
Which trade-off matters?
Completely concealing a junction may look attractive but make later inspection harder. Compare a closed finish with a solution keeping vulnerable points accessible.
What belongs in the budget?
- Survey, investigations and design preparation.
- Demolition, foundations, structure and new building elements.
- Electrical, water, heating and ventilation work.
- Windows, floors, walls, kitchens and bathrooms.
- Access, protection, scaffolding and waste removal.
- Clearly identified provisional sums and change arrangements.
A starting price needs a defined scope.
Ask for work, materials, VAT, assumptions and provisional sums to be clearly described. Undecided items should remain visible so an early estimate is not mistaken for a fully developed final budget.
