Most price disputes do not start from the number itself, but from the absence of an explanation for it. The open-cost model simply means the buyer sees the components of the cost, not only the total.
The four components
- Land share attributed to the unit by area.
- Structure and construction works with approved quantities.
- Finishing according to the agreed specification sheet and samples.
- Management and supervision as a declared percentage, not a hidden margin.
We build trust in every detail — and cost is a detail that deserves to be written down.
With this model, any change in specification has a visible price impact, and the owners' union can approve or reject it in a documented decision before execution.
