Nearly 2,000 new residential projects recorded in Attica as price gaps widen

According to data from ReDataset’s BuildBoard platform, which tracks new construction projects across Greece, 1,939 new residential construction projects were recorded in Attica between January and September 2026.

Combined with listings for newly built homes for sale, these figures highlight both the areas attracting the greatest concentration of new construction activity and the significant differences in residential acquisition costs.

Eastern Attica Accounts for 36% of New Residential Projects

Construction activity is unevenly distributed across Attica’s regional units. Eastern Attica ranks first, with 694 new project records, accounting for 36% of the total.

It is followed by the Northern Athens Sector with 343 records, the Southern Athens Sector with 222 and the Central Athens Sector with 211. At the other end of the spectrum, Piraeus records just 86 new residential projects, the lowest figure among the regional units.

However, the number of projects alone does not indicate either the scale of construction or the number of homes expected to be delivered. The type of building developed in each area is also a decisive factor.

Detached Houses Dominate Eastern Attica, While Apartment Buildings Prevail in Central Athens

In Eastern Attica, 468 of the 694 recorded projects involve detached houses and maisonettes, confirming the dominance of these residential formats in the area’s new construction activity.

A similar pattern is evident in the Islands of Attica, where detached houses account for 115 of the 137 new project records. Aegina leads with 49 projects, followed by Kythera with 31 and Salamina with 27. In addition, 32% of new buildings in the area form part of residential complexes, compared with 10% across Attica as a whole.

Detached houses also dominate Western Attica, accounting for 67 of the 105 new project records. Megara leads with 36 projects, followed by Fyli with 26. A notable feature of the area is that 92% of new buildings are developed by private individuals, compared with 65% across Attica overall.

By contrast, apartment buildings dominate the more densely developed parts of the metropolitan area. In the Central Athens Sector, 94% of new project records concern apartment buildings, while the corresponding share in the Southern Athens Sector stands at 86%.

Within the Southern Athens Sector, Glyfada stands out with 63 project records. At the municipal level, however, the Municipality of Athens records the highest number of new residential projects in Attica, with 102, narrowly ahead of Pallini, which follows with 100.

Differences in the Characteristics of New Buildings

Regional variations extend beyond housing types to the technical characteristics of newly constructed buildings.

In the Southern Athens Sector, the average floor area of a new building reaches 710 sq m, almost twice the Attica-wide average of 380 sq m.

In the Northern Athens Sector, 92% of new buildings include a basement, compared with 74% across Attica. In the Western Athens Sector, 82% feature a pilotis, compared with 38% across the region as a whole.

In Eastern Attica, 30% of new buildings include a swimming pool, compared with 21% across the wider metropolitan area.

These figures point to distinct development patterns shaped by the types of housing and building specifications favoured in each location.

Indicative Cost of a Newly Built 100 sq m Home Reaches €456,000

Beyond new construction activity, significant differences are also evident in the asking prices of newly built homes listed for sale.

Based on property listings for 2026, the median asking price across Attica stands at €4,560 per sq m. For a 100 sq m home, this translates into an indicative purchase price of €456,000, excluding additional transaction costs.

The Southern Athens Sector records the highest indicative budget, at €502,000 for a 100 sq m property. It is followed by the Northern Athens Sector at €479,000 and the Central Athens Sector at €452,000.

Lower prices are recorded in Eastern Attica, at €406,000; Piraeus, at €377,000; and the Western Athens Sector, at €347,000.

The difference between the Southern and Western Athens sectors amounts to approximately €155,000 for a home of the same hypothetical size, highlighting the pronounced geographical disparities within the market.

Where the Most and Least Expensive Municipalities Are Located

Price differences become even more pronounced at the municipal level. Vari–Voula–Vouliagmeni ranks first, with an indicative cost of €756,000 for a newly built 100 sq m home.

It is followed by Glyfada at €640,000 and Alimos at €600,000. The presence of four of the six most expensive municipalities along the southern coastal corridor highlights the substantial price premium associated with this part of the market.

At the other end of the spectrum, Spata–Artemida records the lowest indicative cost, at €301,000. Keratsini–Drapetsona follows at €315,000, while Pallini stands at €333,000.

The indicative cost of a newly built home in Vari–Voula–Vouliagmeni is therefore approximately 2.5 times that in Spata–Artemida. In other words, the asking price of a newly built property of the same size can differ by hundreds of thousands of euros, even within the same broader metropolitan market.

The Geography of New Housing and the Cost of Acquisition

ReDataset’s figures paint a picture of a market characterised by distinct development patterns and pricing dynamics. Eastern Attica accounts for the largest share of new residential projects, with detached houses and maisonettes predominating, while apartment buildings dominate the Central and Southern Athens sectors.

At the same time, asking prices reveal a wide range of acquisition costs, both across regional units and between individual municipalities.

For prospective buyers, location is therefore a decisive factor in determining the required budget. For market analysts, tracking new construction projects provides valuable insight into the housing supply taking shape before properties reach the sales market.
