CGS Ellinikon
Private school, announced for 2028 · The Ellinikon, Elliniko
The first private school on this coast, on Lamda land at The Ellinikon, contracted to open in September 2028. Announced rather than built.
Commercial relationship
None. LivingTheta has no commercial relationship with Costeas-Geitonas School, Inspired Education or Lamda Development, receives nothing from it, and takes no fee from any school or placement adviser.
- Status
- Announced, not open Contracted opening September 2028. Nothing on this page describes a school that exists.
- Where
- The Ellinikon, on the former airport site
- Operator
- Costeas-Geitonas School Under a Lamda Development lease signed 15 May 2024: 30 years, renewable for another 30, with rent set annually as a share of turnover.
- Registrations
- From September 2027 A year before opening, with priority reported for pupils already at CGS.

- Planned size
- 1,500 to 1,700 pupils
- Planned building
- Three storeys, open swimming pool, outdoor sports, planted roofs
- Ownership behind it
- Inspired Education Group Nadim Nsouli’s group, reported at 115 schools, took the majority of CGS. In August 2024 Olympus Investment, controlled by Vasilis Laliotis, had acquired 89% through a €20.2 million capital increase.
- Distance
- 9.2 km from Vouliagmeni 2.8 km from Glyfada, 0.0 km from Elliniko. Straight-line — the road is longer, and in term-time traffic longer again.
Lamda Development has signed a lease with Costeas-Geitonas School — thirty years, renewable for a further thirty — over 31,761.96 square metres at The Ellinikon, for a primary and secondary school reported to open in September 2028 with 1,500 to 1,700 places.
The published plan is a three-storey building with an open swimming pool, outdoor sports facilities and planted roofs.
Why this matters more than any other school on this list
Because there is no private school on this coast at all. The nearest is Geitonas at Vari, which is Greek-curriculum, and the nearest British school is at Koropi. Everything international is more than twenty kilometres north-east.
That absence is the single fact that reorganises the property map on this coast. A school inside The Ellinikon changes it.
What is not yet known
The curriculum and the language of instruction. CGS at Pallini runs the Greek curriculum alongside IB programmes; which of those comes south, and whether the school is international in the sense a relocating family means, has not been settled publicly.
That is the question to put to anybody selling on the strength of it, and it is a fair question because 2028 is three admissions cycles away.
Announced is not delivered
This site prints what is delivered separately from what is announced, and the Elliniko address file keeps that distinction for the whole development. A signed thirty-year lease with an international operator is strong evidence, and it is still evidence about the future.
