Set in Elefsina, near Athens, Tri-Edge Residence is conceived as a private home defined by a single geometric gesture. A triangular canopy frames the first floor and gives the house its identity from the street, while a muted palette of stone and render, a timber boundary screen and cross-ventilation strategy anchor the home to its Mediterranean setting.
Tri-Edge is a contemporary villa in Attica, designed for a private client seeking a home that combines architectural identity with a quiet relationship to its suburban setting. The triangular canopy at first-floor level establishes the architectural signature from the street, organising the elevation and creating a continuous line of shade that reduces solar gain on the south-facing facade. Beneath it, a vertical timber screen mediates between street and courtyard, offering privacy without closing off views and air.
The material palette of this contemporary villa in Attica is deliberately reduced — stone at ground level anchors the building to its plot, while smooth render on the upper level reflects the bright Mediterranean light. The interior is organised around a sheltered outdoor courtyard, with living and dining spaces opening toward it through tall sliding panels. This courtyard acts as a thermal buffer and as the social heart of the home, drawing the family’s daily routines outdoors for most of the year.
Tri-Edge’s environmental design strategy is integrated into its architectural form rather than added afterwards. Cross-ventilation paths run through the public spaces, the timber screen filters morning sun, and the triangular canopy provides passive shade across the long Mediterranean summer. As a contemporary villa in Attica designed by ONUS Architecture Studio, the project demonstrates how a single architectural gesture can resolve identity, privacy and environmental performance together.
Tri-Edge Residence has been featured in international distinctions including the Architizer A+ Awards. Built within the Elefsina region — Greek European Capital of Culture 2023 context — the residence is part of ONUS’s sustainable residential architecture in Greece and the studio’s international architectural recognition.
