Castelldefels is where a headline price per square metre is least useful. Five kilometres of beach, a slope behind it and a direct train to Barcelona produce a market where two houses with the same built surface can be a third apart in price for reasons that have nothing to do with the house.
Position decides the price here
Guide values differ sharply by position: apartments run around €3,800/m², houses around €4,600/m² and villas around €5,800/m², with the beachside streets and the Bellamar and Montemar slopes at the upper end.
Knowing which side of that spread a specific street sits on is the whole job. We price the property you are looking at against what comparable homes in that exact position actually achieved, not against the town average.
The international family market
A British School of Barcelona campus in the town is why many international families settle here rather than in Barcelona itself, and it shapes demand: proximity to the school run, a garden, and a commute that works on the R2 line.
That demand is also why well-positioned family houses sell quickly and often quietly. As your buyer’s agent we hear about them through the local agency network before they reach the portals, and we can view on your behalf if you are not in Spain.
What we verify before you commit
Older villas on the Bellamar and Montemar slopes frequently carry extensions, pools or terraces that were never legalised, and access and parking vary street by street. On the beach side, the questions are different: setback rules, community charges on the low blocks, and what the property actually looks at.
We check the registry, the cadastral surface and the licence position before the arras contract, and coordinate a lawyer and, where the house warrants it, a surveyor.
| Property type | Guide value | What moves it |
|---|---|---|
| Apartment | €3,800/m² | Distance to the beach and to the station |
| House | €4,600/m² | Plot, condition and whether works were legalised |
| Villa | €5,800/m² | Beachside streets and the Bellamar / Montemar slopes at the top |

Frequently asked questions
Do you work as a buyer's agent in Castelldefels?
Yes. Castelldefels is fifteen kilometres from our Sitges base and one of the markets we cover directly, including Bellamar, Montemar, the beach streets and the town centre.
How much does property cost in Castelldefels?
Guide values differ sharply by position: apartments around €3,800/m², houses around €4,600/m² and villas around €5,800/m², with the beachside streets and the Bellamar and Montemar slopes at the upper end. The gap between a street near the sand and one on the slope is significant.
Is Castelldefels good for international families?
It is one of the main reasons people choose it. The town has five kilometres of beach, a direct train to Barcelona and a British School of Barcelona campus, and a long-established international community.
What should I check before buying a villa in Castelldefels?
On the slopes, whether extensions, pools and terraces were legalised, plus access and parking. On the beach side, setback rules, community charges and the actual outlook. In both cases the nota simple and the cadastral surface against what is being advertised.
