Castelldefels is the market where a town-wide price per square metre is least useful to a seller. Five kilometres of beach, a slope behind it and a direct train to Barcelona mean two homes of the same built surface can be a third apart in price, and listing yours against the town average leaves money on the table or scares buyers off.
The price is in the position
Guide values run around €3,800/m² for apartments, €4,600/m² for houses and €5,800/m² for villas, with the beachside streets and the Bellamar and Montemar slopes at the top of each band. Where exactly a home sits on that spread is the whole valuation.
We price your property against what comparable homes in that exact position actually achieved, not against the town figure, so it launches at a number buyers recognise as fair rather than one they discount on sight.
Selling to the international family
A British School of Barcelona campus in the town, five kilometres of beach and the R2 line into Barcelona are why international families settle here, and well-positioned family houses with a garden and a workable school run sell quickly and often quietly.
We reach those buyers directly, through the local network and, where the move involves another country, through our association with Hamptons International, rather than waiting for them to find a portal listing.
Settled before it is listed
Older villas on the Bellamar and Montemar slopes frequently carry extensions, pools or terraces that were never legalised, and that is the question most likely to break a sale during the buyer’s due diligence. On the beach side the issues are setback rules and community charges.
We establish the registry, the cadastral surface and the licence position before the home goes to market, so nothing surfaces late that forces a renegotiation.
| Property type | Guide value | What moves it |

| Villa | €5,800/m² | Beachside streets and the Bellamar / Montemar slopes at the top |

Frequently asked questions
How much is my property in Castelldefels worth?
It depends sharply on position: apartments run around €3,800/m², houses around €4,600/m² and villas around €5,800/m², with the beach streets and the Bellamar and Montemar slopes at the top. A valuation has to compare your home to others in the same position, not to the town average.
What is the best way to sell a villa in Castelldefels?
Settle the legal questions first, extensions, pools and terraces that may not be legalised, then price to the exact street and position, and market to the international family buyer directly rather than only on the portals. That combination avoids the late renegotiation that stalls most slope-villa sales.
Who buys property in Castelldefels?
A large share are international families drawn by the British School of Barcelona campus, the beach and the direct train to the city, plus Barcelona buyers wanting space and sea. Well-positioned family homes sell quickly and often before they are widely advertised.
What should I legalise before selling in Castelldefels?
On the slopes, any extensions, pools or terraces built without a licence, and discrepancies between the cadastral surface and what is advertised. Sorting these before listing is almost always faster and cheaper than discovering them during a buyer’s due diligence.
