The real estate market in Catalonia continues to reflect a clear trend in 2026: new construction remains the most expensive product compared to second-hand housing, even when the latter has been renovated. In Buckingham Property Advisors We know that this difference is not only due to the state of the property, but also to factors such as energy efficiency, services, and location.
Overall, the most recent data indicate that new construction can be up to 40% more expensive than resale homes. Even so, a comprehensive renovation can increase the value of an apartment by between 30% and 40%, significantly narrowing that gap.
In Barcelona, the price difference between a renovated home and a new-construction home typically ranges from 15% to 30%. High demand and a shortage of land drive up prices for both types of properties, although new-construction homes continue to stand out for their modern features and energy efficiency.
In coastal areas such as Castelldefels and Sitges, the price difference is even greater. Here, new construction can be between 30% and 50% more expensive than a renovated home. This is due to the exclusive nature of the market, international demand, and the limited availability of new developments, many of which offer premium amenities.
In the Maresme region, where the market is more diverse, the difference narrows to a range between 20% and 35%. The greater availability of existing homes reduces pressure on new-construction prices.
For its part, Sant Cugat del Vallès occupies a middle ground, with prices ranging from 25% to 40%. It is a highly sought-after area among families and buyers with high purchasing power, where new construction is particularly attractive.
In conclusion, although renovated housing can be a competitive alternative, new construction still maintains a significant premium. As we know as experts in the real estate market Buckingham Property Advisors, factors such as energy efficiency, common areas, and the “first-time buyer effect” continue to make a difference in the final price.
