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

Compare the complete intervention
Separate structural function and visible finish quality in the budget. Ask which preparation, protection and finishing are included when an element remains exposed.
Which trade-off matters?
An exposed beam makes the construction legible but changes requirements for junctions and services. Compare exposed and concealed solutions using the same structural assumptions.
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.

Consider preparation, protection, timing and reinstatement alongside the total price.
