NEW-BUILD · PROVINCE OF BARCELONA
New-build homes are valued 19% above resale
€4,070/m² against €3,414/m² for second-hand housing.
In the province of Barcelona, new-build square metres are valued at €4,070 and resale ones at €3,414: a 19% gap.
The gap explains why refurbishment features in every housing plan: the existing stock is vastly bigger than what gets newly built, and fixing it up costs less than raising it from scratch.
For an owner, that has a direct reading: renovating before selling doesn't always pay off, but a flat in move-in condition and one that needs work part ways in price by considerably more than the renovation actually costs.
There's also a real tax difference between the two, not just price: new-build pays VAT (plus stamp duty), while resale housing pays transfer tax. The rate isn't the same, so two flats at an identical final price don't cost the same to put through the notary.
For someone buying to live in, the question that actually matters isn't which is cheaper on average, but how much time and money it takes to get a resale flat move-in ready versus walking straight into a new one — the 19% gap doesn't include that reckoning.
