Scenario A
- GroundGentler levels shown
- AccessRoad access still to verify
- ServicesShorter routes illustrated
- DrainageStrategy still required
Land & permission
Before you choose the house, understand the land.
A plot can affect what may be built, how the home must be supported, how construction reaches it and what the complete project requires.
Scope boundary
This page explains the checks. It does not confirm planning permission, ground suitability or final cost for a specific plot.
One home · two starting conditions
The image above ground can remain almost unchanged.
Scenario B
- GroundSlope and levels to survey
- AccessConstruction route to verify
- SupportFoundation and retaining design
- WaterDrainage path to investigate
Illustrative scenarios. The generated images do not confirm buildability, engineering, quantities or cost.
What this shows
Why site-dependent work can change while the home stays recognisable.
What it cannot tell you
Whether either illustrated plot is legally or technically suitable.
What still needs checking
Planning, survey, ground, access, water and service conditions.
Evidence state
Mechanism illustrated; both scenarios remain project assumptions.
Five checks before confidence
No photograph or property listing can answer all five.
Planning
What do the applicable plans and constraints allow, and which project-specific municipal route can establish greater certainty?
Ground & levels
What do the survey and investigation say about slope, soil, rock, water and the foundation concept?
Water & drainage
Where does surface water arrive, where can it go, and what wastewater solution is available and permitted?
Access & construction
Can people, deliveries and equipment reach the working area safely, and what temporary or permanent work is required?
Services
Where are electricity, water and communications, how long are the routes, and which connection conditions still need confirmation?
Current-source note
Portuguese planning procedures and legislation change. Check the current municipal position and project route; do not treat this prototype as legal confirmation.

A useful result
The goal is not always “yes”. It is a decision with fewer hidden conditions.
The required evidence supports the present decision boundary.
Named conditions must be resolved before the next commitment.
A material unknown could still change feasibility, design or budget.
The finding conflicts with the project brief or acceptable risk.
A negative finding before purchase can be a successful decision.
