Athens Metro Line 4 (2026): How it's redrawing the property demand map

Line 4 is the largest infrastructure project under way in Athens and it is already reshaping housing market expectations — before the first train runs. Below: what we know today about the project and how that translates into prices and demand by neighbourhood.

The project in numbers

12.8 km automated line (Phase A: Alsos Veikou → Goudi).
15 new stations.
End of 2026: tunnel excavation by TBMs "Athina" and "Niki" expected to complete.
2029-2030: estimated operational date.

Phase A's 15 stations

Stations along Line 4 (Alsos Veikou → Goudi):

Alsos Veikou
Galatsi
Elikonos
Kypseli
Dikastiria
Exarchia
Akademia
Kolonaki
Kaisariani
Panepistimioupoli
Ilissia
Zografou
Goudi

(Three interchange stations with existing lines are included in the 15.)

How the demand map is being redrawn

Following the announcement of exact station locations, property portals recorded asking-price increases of up to 58% on streets near new stations. More conservatively, historical data from previous Athens metro extensions suggests a 12-15% step-up for properties within 500m of a new station.

Forecast for Line 4 areas (Kypseli, Exarchia, Galatsi):

5-8% annual growth as construction advances toward 2029.
Compared with a 4-6% average for the Athens market over the next 12 months.

Which neighbourhoods gain the most

Kypseli

The historic interwar neighbourhood — no metro until now. The connection is a material upgrade for renovated apartments, especially around Fokionos Negri.

Exarchia

Demand for neoclassical and small apartments is already strong — the new station will reinforce demand from tenants and investors seeking quick centre access.

Galatsi

Directly bordering Gyzi and Kypseli. A traditionally family-oriented area with good schools — Line 4 gives it direct metro access to the centre for the first time.

Zografou / Ilissia

The university pair. Steady student-housing demand expected to intensify with a one-line connection between campus and centre.

What it means for buyers

Pre-construction premium: today's buyers are already paying for some of the "future metro" upside. Confirm against comparable properties in metro-less neighbourhoods before pricing your offer.
Distance from station: strongest price correlation within 500m of an entrance. Beyond 800m the effect fades quickly.
Timing: completion expected 2029-2030. Appreciation isn't immediate — it plays out across years with milestones (tunnelling, station fit-out, testing).

What it means for sellers

If your property sits in a Line 4 zone and your asking price hasn't been adjusted, revaluation is worthwhile. The market within 500m behaves differently from the rest of the neighbourhood.

What it means for investors

Line 4 is one of the few "certain" neighbourhood-level catalysts in Athens. Combined with central-area housing undersupply and household demand returning (not just tourism), Line 4-corridor properties remain a defensive choice.
