An older property in the Algarve can offer something a new build never can — an established location, a mature plot, and often a price that leaves room in the budget to do something exceptional with it. But older properties come with things that surveys miss and drawings don't show. Here's what you are actually taking on, and how to manage it properly.
The Algarve's property market has two distinct categories of older stock. There are the well-maintained villas that have been updated progressively over the years and carry a relatively straightforward renovation scope. And then there are the buildings constructed before 2000, which are a different matter entirely.
Portugal in that period had building regulations. Whether they were followed is another question. Construction practices were inconsistent at best, and it was not unusual for structural decisions to be made on site, without engineering oversight, in ways that would not be permitted today. The result is a generation of properties that look solid from the outside, pass a standard survey, and then reveal their real character the moment you open up the walls.
What You Find in an Older Algarve Property
In our experience, almost every serious renovation of a pre-1990 Algarve property produces at least one finding that was not on any drawing, not flagged in any survey, and not something anyone could have known about without physically getting into the fabric of the building. Sometimes it is a structural element that was never built to the specification it should have been. Sometimes it is a drainage or electrical installation that has been extended and modified so many times it bears no resemblance to anything original. Sometimes it is something in the ground beneath the building that changes what the foundations can support.
None of this means old properties should be avoided. Some of the best projects we have managed have been renovations of older buildings — and the results, when done properly, are often more interesting than anything a new build can produce. But it does mean that the management of a renovation project is fundamentally different to the management of a new build. On a new build, you are executing a plan. On a renovation, you are executing a plan while simultaneously responding to what the building tells you as you go. The two skills are not the same.
A Full Remodel in Carvoeiro
The project at Vale Centeanes, Carvoeiro is a good illustration of what a serious renovation actually involves. The property was built before 2000 — a four-bedroom villa in one of the most desirable coastal addresses in the central Algarve, close to the beach and the village of Carvoeiro. The brief was a full remodel, with partial demolition of sections that could not be made to work within the new design.
Once we were into the structure, the findings began. Non-compliant elements that had to be addressed before the remodel could proceed. Areas where the original construction had taken shortcuts that decades of exposure had quietly been making worse. Each finding required a decision: how to resolve it, what it meant for the programme, what it cost. That decision-making process, repeated across a project with many moving parts, is where renovations of this type either stay on track or lose control.
We worked with a local architect whose knowledge of both the building typology and the planning requirements for the Carvoeiro area was an asset throughout. The design brief was clear — take everything the building was capable of and realise it properly — and the architecture delivered on that. Orla managed the project from the first brick laid through to handover: every contractor, every subcontractor, every finding, every decision.
What the Building Became
The finished property is a significant step up from what was there. The remodel delivered a fifth bedroom — all five now en-suite — alongside a walkable roof terrace, an outdoor kitchen, and an interior bar area. The structural issues that had been quietly accumulating for years are resolved. The building meets current regulations. And the client has a property in Vale Centeanes that is genuinely exceptional for its location.
That outcome was not inevitable. It required the right architect, the right contractors, and consistent management of a project that threw up more complexity than any survey could have predicted. The location and the plot were always there. Getting the building to match them took work.
What to Think About Before You Start
If you are considering buying an older Algarve property with the intention of renovating it, there are a few things worth understanding before you commit.
01
Surveys only show what is visible
The survey you commission before purchase will tell you what is visible. It will not tell you what is inside the walls, under the floors, or beneath the building. Budget for findings, because there will be some — the question is how significant they are, not whether they exist.
02
Partial demolition is often the right call
Sometimes the most cost-effective thing to do with an element of an older building is to take it down and rebuild it properly, rather than try to remediate something that was never built correctly in the first place. A good architect and an experienced project manager will tell you honestly when that is the right call.
03
Planning has its own considerations
Permitted changes depend on the property's existing licence, its location within any protected zones, and the local Câmara's current policies. Extensions and additions require their own approvals. Changes that alter the building's footprint or volume need to be managed carefully. None of this is insurmountable, but it needs to be understood at the outset rather than discovered mid-project.
04
Your contractor needs renovation experience
Taking apart an existing structure and rebuilding it selectively, around what is being retained, requires skill and care that not every building company has. The wrong contractor on a project like this will cut corners in ways that only become apparent years later.
