The method uses wall-face area and exposes every major adjustment. It returns a result before asking for contact details.
Why quotes move
A metre of wall is not a useful unit on its own.
Height changes wall-face area, loads and construction scope. Access, spoil, drainage, demolition and professional input may matter as much as the visible material.
Method note
The calculator uses wall-face square metres and displays broad planning bands. Coefficients are dated and will be versioned as accepted-quote evidence is added.
- Dimensions
Length × average retained height establishes wall-face area. - Site access and working room
Machine access, slope and temporary support affect labour and equipment. - Water and drainage
A quote should make drainage scope visible rather than hide it inside a flat rate. - Removal and spoil
Demolition, disposal and excavation are separate project decisions. - Engineering and approvals
Requirements depend on jurisdiction and site conditions, not one national height rule.
