Defined home scope
The named model, specification, included work, exclusions, VAT treatment and price date.
Complete project cost
What does it really cost to build a home in Portugal?
There is no responsible total before both the house scope and the land are defined.
Scope boundary
This page explains a budgeting method. It is not a quotation or a total for a specific home or plot.
What this shows
How a defined house-package price relates to a complete project budget.
What it cannot tell you
The final price of an undefined home on an unchecked plot.
What still needs checking
Model, scope, VAT, date, plot, permissions, design and site work.
Evidence state
Method verified; project values remain unknown until documented.
One project · several boundaries
The price of the building is not the price of the finished project.
A usable budget places every necessary part somewhere visible—even when its value is not yet known.
Design, engineering & permissions
Project-specific professional work, submissions and approvals—not a generic allowance presented as certainty.
Ground, foundations & site work
Levels, ground conditions, excavation, structural support and the interface between land and home.
Access, drainage & external work
How construction reaches the site, how water is managed and what must happen outside the house footprint.
Utilities & connections
Routes and connections for electricity, water, wastewater, communications and any project-specific systems.
Fees, taxes & uncertainty
Named fees and taxes, plus a visible allowance for decisions and conditions that are still unresolved.
Compare the same boundary
Two totals are comparable only when their scopes align.
A lower number may simply stop earlier. Before comparing proposals, give every line the same meaning and status.
| Cost boundary | Proposal A | Proposal B | Decision question |
|---|---|---|---|
| Named home scope | Included | Included | Are the specifications genuinely equivalent? |
| Foundations & site work | Provisional | Excluded | Who carries the unresolved ground risk? |
| Design & permissions | Estimated | Unknown | Which professional work has been allowed for? |
| Connections & external work | Excluded | Excluded | Has a separate project allowance been created? |
Illustrative scope comparison. The labels demonstrate method; they are not offers or current prices.
Make uncertainty visible
A number is only as useful as its status.
A current document applies to the named scope and decision.
A working input is visible, but still needs project evidence.
The necessary information does not yet exist or has not been checked.
Unknown is not zero. It is a prompt to investigate before the decision becomes expensive.
The land moves the total
The house can be defined while the project is not.
Foundations, drainage, access and service routes remain specific to the plot.
