OLIAROS Development was founded in 2001 by Iasson Tsakonas, focusing on the boutique, residential sector in the Greek islands. Our first development launched in Antiparos with seven houses on the west coast of the island, growing to a portfolio of more than 50 properties today.
Over the years, we have worked with more than 25 different architects to build responsibly in dialogue with sustainability, community and landscape — helping to establish Antiparos as a landmark residential destination. Our in-depth knowledge of the island and our on-the-ground team allows us to offer our clients a personalized, hospitality-driven experience, from buying land and design concepts to post-sales services.
OLIAROS Villa Rentals was born in 2013, combining exceptional vacation rental properties in Antiparos and beyond with concierge services led by a local team. Beach House Antiparos opened in the same year as a meeting place and service point for our clients and the wider island community. Sold in 2024, BHA remains our concierge hub for both residents and guests.
In 2021, OLIAROS began working on a small residential project in Sifnos, that harmonizes with the island’s nature. The Sifnos Project proposes a new concept in line with the island’s unique identity, architecture and cultural character. While our development principles remain the same, our approach is tailormade to each destination.
PRINCIPLES
ACCOUNTABILITY
In each destination, we engage in a dialogue with the landscape, community, culture and infrastructure of an island in order to preserve its authenticity. OLIAROS founder Iasson Tsakonas is the co-founder of the Cyclades Preservation Fund, which provides funding and support for island-led initiatives; our unique development process involves intensive research and workshop phases; while we strive to maintain the existing social balance of each island by curating a diverse, family-orientated clientele that finds value our proposed way of living, and ethos of life.
SUSTAINABILITY
We are committed to utilizing innovative sustainability practices across our projects, whether maximizing bioclimatic design to limit the use of AC, ensuring our designs integrate seamlessly into the landscape, collecting rainwater or installing PV panels — with a view to our properties becoming 100% self-sufficient. The Antiparos Project is the first development in the Cyclades to adopt a PV park model on the Greek mainland, establishing the OLIAROS Energy Community.
BALANCE
Our developments are carefully integrated seamlessly into the existing landscape, while we work in close collaboration with landscape architects to build in harmony with the Cycladic ecosystem. Respecting the character and language of the destination’s unique environment, we utilize a dry planting strategy, which takes inspiration from local rhythms, colors, structures and scents.
