Nou Barris and Horta-Guinardó: Property for the Investor
Nou Barris and Horta-Guinardó are among the cheapest districts in Barcelona by asking price, so renovation takes a larger share of the budget there. Annual growth is high but from a low base.
Property in Nou Barris and Horta-Guinardó costs less than the rest of Barcelona: Idealista data for September 2026 show asking prices of 3,318 €/m² and 4,198 €/m² against a city average of 5,462 €/m². For an investor that means a small cheque and a large share of renovation in the budget. The districts suit careful work on a specific building, not a bet on prices "going up".
What a metre costs in the two districts
Asking prices from the Idealista report of 6 October 2026 (period: September 2026):
| District | €/m² | Over 12 months |
|---|---|---|
| Nou Barris | 3,318 | +17.1% |
| Sant Andreu | 3,998 | +10.8% |
| Horta-Guinardó | 4,198 | +8.8% |
| Barcelona average | 5,462 | +5.8% |
Nou Barris is the cheapest district in the city and is also growing fastest. The 17.1% growth is measured from a low base; it is a history of listings, not of closed deals, and not a forecast. The gap between the listing price and the deal price is covered in the article on asking price versus closing price.
Two districts, two different kinds of building
Nou Barris is divided into 13 neighbourhoods (barris), Horta-Guinardó into 11. According to NacióDigital, Nou Barris was created as a separate municipal district on 18 January 1984 and was originally planned as nine neighbourhoods. Neighbourhood by neighbourhood it is residential development of the second half of the twentieth century, with the usual questions for such buildings: lift, facade, condition of the common parts. Each building has to be checked separately.
Horta-Guinardó climbs towards Collserola. The relief gives views and quiet, but also steep streets, retaining walls and difficult access for machinery. The district includes Horta, El Carmel, El Guinardó, La Teixonera, Montbau and La Vall d'Hebron. I found no exact figures by neighbourhood in open reports, so a specific street is compared with sold comparables, not with the district average.
Transport: confirmed lines
Nou Barris is served by L3 (stations Roquetes, Canyelles, Trinitat Nova), L4 (Via Júlia, Llucmajor, Maragall, Trinitat Nova) and the light metro L11 with a stop at Torre Baró | Vallbona, where you can change to Rodalies. Horta-Guinardó: L5 (Vall d'Hebron, El Coll - La Teixonera, El Carmel, Horta) and L3 (Vall d'Hebron, Montbau, Mundet). Check line maps and service interruptions on the TMB website.
What is happening in the districts: Pla de Barris
Pla de Barris is an Ajuntament programme of investment in socially vulnerable neighbourhoods. According to a Vilaweb report of 25 March 2025, the plan includes 315 measures through 2028, about 300 M€ and 27 neighbourhoods in seven districts. For Nou Barris it names Ciutat Meridiana, Torre Baró and Vallbona: per an Ara article, 11.3 M€ will go there through 2028, for housing, healthcare and education. This is public spending on improving the area, and there are no open calculations of its effect on prices.
What to check when buying
- Lift. A building without a lift sells at a discount, but installation depends on the owners' community and on engineering, see installing a lift in an old building.
- Condition of the building. For buildings over 45 years old, request the ITE report (building inspection) and details of the facade and roof: what to look at in it.
- Cédula and documents. Without a valid cédula de habitabilidad (certificate of habitability), letting and a number of transactions become complicated; the procedure is in the article on the cédula.
- Actual condition and occupancy. View the flat before the arras (deposit contract), and check who lives in it and on what basis. The risks are described in the article on squatting.
- Rental regime. Barcelona is in a stressed-market zone, with details in the article on the rent ceiling.
Worked calculation: why renovation "weighs" more in a cheap district
Worked example, not a forecast. A 70 m² flat, renovation at a round 1,000 €/m², that is 70,000 €. At an asking 3,318 €/m² the purchase costs about 232,300 €, and the renovation is roughly 30% of it. At 4,198 €/m² the purchase is about 293,900 €, and the renovation share is roughly 24%. In central Eixample (6,648 €/m²) the same work comes to about 15%.
What this means: the lower the entry price, the larger the relative uplift the sale must deliver to cover the works, taxes and costs. Whether local buyers pay for renovation is shown only by sold renovated comparables. The full list of costs is collected in the article on the full budget of an investment project.
Who these districts do not suit
They do not suit those who want a forecast: "the district is rising" cannot be verified, and the one-year price growth in Nou Barris starts from a low base. They do not suit those who need an easy exit: the liquidity of renovated flats in a specific neighbourhood is not known in advance. They do not suit those planning short-term lets: Barcelona's tourist licences are planned to be phased out by November 2028, see the article on the ban. And they do not suit those unwilling to inspect a building in person: an averaged district figure says nothing about access, the lift and the neighbours.
For a first comparison of whole districts, the article on criteria for choosing a district is useful. The entry price and budget of a specific flat can be run through the investor calculator.
Questions and answers
Which district of Barcelona is the cheapest?
By Idealista asking prices for September 2026 it is Nou Barris: 3,318 €/m². Next come Sant Andreu (3,998) and Horta-Guinardó (4,198).
Why are prices in Nou Barris growing fastest?
Per Idealista, +17.1% over the year, but measured from the lowest price in the city. The report names no causes, and I do not guess at them.
How do I get from Nou Barris to the centre?
By L3 from Trinitat Nova, Roquetes or Canyelles, by L4 from Via Júlia and Llucmajor. Check journey times in the TMB planner.
Is it worth buying a flat without a lift in Horta-Guinardó?
Only after checking whether a lift can be installed in that building, and at a price that takes it into account. The decision is made by the owners' community.
