Kallithea residential market sees growing new-build presence alongside dominant 1970s stock

According to an analysis by ReDataset, a new wave of construction has already established a significant presence in the Kallithea area. This development affects not only the age of available properties, but also their energy performance, asking prices and the types of properties most commonly found on the market. Based on unique residential property listings recorded in 2026, ReDataset examined the profile of the Kallithea housing market across seven key dimensions.

The 1970s clearly dominate the available housing stock

45% of homes offered for sale were built between 1970 and 1979. At the same time, however, properties built from 2020 onwards already account for 24% of total supply. This creates a market with two distinctly different segments: a large, mature housing stock and a newer segment that is expanding rapidly.

The ageing housing stock is also reflected in energy ratings

The age of the housing stock is also reflected in its energy performance. Overall, 65% of homes are rated Energy Class C or lower, while only 13% are rated A+. The most common individual rating is Class E. The market therefore combines newer properties built to higher standards with a substantial proportion of older housing stock characterised by lower energy ratings.

Smaller and mid-sized apartments dominate

Kallithea is a dense, centrally located residential market in which smaller and mid-sized apartments have a strong presence. The most common size category is 50–70 m², accounting for 26% of the market. This is followed closely by properties measuring 70–90 m², at 25%, and 90–120 m², at 24%. Meanwhile, 16% of homes are smaller than 50 m², while only 8% exceed 120 m².

New-build properties cost approximately twice as much per square metre

Property age is strongly correlated with asking prices. Homes dating from the 1960s have a median asking price of approximately €2,050/m², while the corresponding figure for properties built from 2020 onwards reaches €4,110/m². The difference is approximately twofold, and the trend is consistent: the newer the property, the higher its median asking price per square metre. The median asking price across the municipality as a whole stands at approximately €2,650/m².

Approximately €200,000 for a typical three-room apartment

For a property measuring 70–90 m², the median asking price stands at approximately €200,000. For properties between 50 and 70 m², the figure is approximately €145,000, while homes smaller than 50 m² start at around €102,000. Within the 70–90 m² category, the middle 50% of asking prices range from approximately €165,000 to €275,000, indicating significant variation even among properties of the same size.

The energy premium is primarily a new-build premium

Energy ratings also show significant variation in asking prices. A+ properties are approximately twice as expensive per square metre as those rated Class H. However, this difference should not be interpreted as being attributable solely to energy efficiency. Most A+ properties are relatively new or newly built, meaning that their energy rating also largely reflects the age of the construction. In other words, the “energy premium” is to a significant extent also a premium associated with newer properties.

Strong presence of the rental market

Kallithea is not solely a sales market. 42% of new residential listings in 2026 are for rental, while properties offered for sale account for 58%. This translates into approximately two new rental listings for every three sales listings. This profile reinforces Kallithea’s position as a central residential market characterised by strong activity in both the owner-occupied and rental segments.

Two eras, one market

Kallithea is not defined simply by its ageing housing stock. Its defining characteristic is the coexistence of two distinct market segments: properties dating from the 1970s, which continue to constitute the core of available supply, and a significant volume of newer housing stock offering higher energy standards and substantially higher asking prices.

At the same time, the dominance of small and mid-sized apartments, together with the strong presence of the rental market, continues to underpin Kallithea’s character as a dense, centrally located residential market.
