Some fall in love with the sea from a hill.
Some see an estate surrounded by pines and already imagine slow breakfasts on the terrace.
And some, faced with an empty plot, see much more than dirt and scrub: they see the future.
But before letting yourself be carried away by that feeling (which is legitimate — and welcome), it’s wise to pause for a moment. Choosing the plot to build a villa on the Costa del Sol is a critical decision, one of those that makes the difference between a dream fulfilled… and a dream full of obstacles.
And I don’t say that only as an architect. I say it because I’ve often seen how a poorly chosen plot can condition (or even block) a lifetime project.
This article is born from that: from the desire to accompany you through the least glamorous but most decisive part of the whole process. The choice of land. Your land. The place where everything begins.
Before you take the first step
Anyone looking for plots in Marbella, Benahavís, Estepona or Sotogrande usually knows what they want to build: a villa with character, with views, with a garden, with tranquillity.
What they don’t always know is how to tell if a plot really allows that.
That’s why this guide isn’t meant to sell you the perfect parcel. It’s meant to help you choose it.
Throughout these lines you’ll discover:
- Which technical factors you should analyze before falling in love with a plot (slope, orientation, easements, buildability coefficient…).
- Why two parcels of the same size can have very different possibilities.
- How to interpret urban planning terms without being a technician.
- What “urban land” and “rustic land” actually mean.
- Practical steps to make an informed decision.
- And how to avoid the most common mistakes others have paid for with time, frustration and money.
If you’re at the stage of browsing listings, visiting plots with your phone in hand, this text is for you.
What you can’t see from the road: understanding the plot beyond the landscape
First impressions matter—but they aren’t everything
Some plots grab you at the first glance.
You get out of the car, breathe the country air, look to the horizon and say: “this is it.”
And you might be right.
But that “ideal” plot can also hide more limitations than opportunities.
The slope: friend or foe?
A sloped parcel can seem complicated.
But when well managed, it can gift you with split levels, views, privacy and terraced architecture that stands out.
I’ve worked on plots with a 30% incline that became unique villas, where every floor has its own terrace opening to the landscape.
That said: they require a more complex structural design, more earthworks and meticulous planning.
On the other hand, completely flat plots may appear simpler… but sometimes they lack views, are more exposed to neighbours or traffic.
Conclusion: there is no perfect plot, but there are plots that suit what you want to build better.
Orientation: more than just light
On the Costa del Sol, the sun is a factor you can’t ignore.
Its path over the site determines much more than light: it determines thermal comfort, energy consumption and the interior-exterior life of your future villa.
- South or southwest orientation: ideal for capturing winter sun and enjoying sunsets.
- East orientation: for those who love sunny breakfasts.
- North orientation: cool in summer, but can be cold in winter.
And note: good orientation isn’t always about the façade. Sometimes it’s about the play of volumes, porches and vegetation.
How to know if that plot you like… truly suits you
First: what type of land is it?
Urban land
Already has services: water, electricity, sewage, sidewalks.
It’s buildable immediately (if you comply with regulations).
It may have restrictions under the general plan: heights, styles, setbacks.
Rustic land
Only allows agricultural or exceptional constructions.
Not suitable for residential villas, except in very specific (and complex) cases.
If in doubt, consult an expert or check the municipality’s general plan. Or better yet: let us do it for you.
Second: how much can you really build?
Here the famous coeficiente de edificabilidad (buildability coefficient or floor area ratio — FAR) comes into play.
- If you have a 1,000 m² plot and the coefficient is 0.20 (20%), you can build 200 m² of floor area. That figure includes porches, that normaly counts as the half of the enclosed areas.
- But if there are setbacks, easements, protected zones or steep slopes, that buildability may be limited.
A “large” parcel does not always mean a large house.
And even if you can build a lot, that doesn’t mean you should. Sometimes less is more, especially if you want harmony with the surroundings, privacy or generous outdoor areas.
Steps you should never skip before choosing your plot for a villa
Step 1: Visit with technical eyes (not just emotional ones)
Bring (or hire) an architect who knows the area.
It’s not the same to view a plot with excitement as it is to view it with experience.
A good professional will quickly detect risks, opportunities and details that will define your investment.
Step 2: Request the urban planning certificate or statement of planning conditions
This will tell you:
- What use is permitted.
- What total area you can build.
- If there are encumbrances (river, coast, public domain…).
- If there’s a pending planning in process or environmental protection restrictions.
You can request it from the Town Hall or ask a professional to handle it.
Step 3: Check utility connections and access
- Is there a real (not only theoretical) connection to water, electricity and sewage?
- Is the access paved and legal?
- Has the road been adopted by the municipality?
- It seems obvious, but it’s not always the case.

Marbella, Benahavís or Sotogrande? It’s more than taste
Each area has its own urban planning, tax and landscape particularities.
- Plots in Marbella: highly sought-after, higher density, but consolidated services.
- Parcels in Sotogrande: more space, controlled environment, luxury developments with their own rules.
- Benahavís: balance between nature, exclusivity and spectacular views.
The ideal? Choose the area according to your lifestyle, not just price per square metre.
Three common mistakes you can avoid
- Buying without a topographic survey.
- Thinking “what you see” is all there is (the subsoil also matters).
- Failing to anticipate the impact of wind, sun or noise until it’s too late.
Before moving on, let me answer the questions likely on your mind
At this point, the usual doubts arise — the ones that don’t always appear in listings, visits or first meetings.
They’re there, and they deserve clear, straightforward answers.
Because it’s not only about metres, plans and permits. It’s about truly understanding what it means to build your villa, which decisions must be made and when they should be taken.
That’s why I share some of the most common questions I receive from people in the process.
What is the minimum plot size to build a villa?
It depends on local regulations. In general, from 800 m² you can design a villa of around 160–200 m² usable area. But everything depends on the partial plan on the area the plot is located or the municipality’s Master Plan (PGOU).
Can I buy rural land and convert it to urban?
In theory, yes. In practice, it’s very complex and lengthy. Better to forget about that kind of land. For a residential project, it’s advisable to opt for consolidated urban land.
Can I build my villa without an architect?
No. Spanish law requires that any new residential build be designed and directed by a licensed architect. Besides, a good architect does more than draw plans: they help you avoid costly mistakes.
When the plot stops being just land… and starts being a home
There comes a moment, once you’ve chosen well, when the plot begins to speak to you.
You look at it and no longer see only ground. You see the firm foundation of something yours, unique and achievable.
Then everything else flows: the plans, the light, the orientation, the layout.
Choosing the right plot is the first great act of design. And as an architect, I can tell you that when that step is taken with sense, knowledge and calm, the rest of the project lines up like a puzzle where each piece fits into its place.
If you’re at that point — you’ve visited, dreamed, compared and now want to decide with confidence — we’re here to help.
Because the land is the root.
And every great villa begins with how you plant it.
