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

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.
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.
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.
