Nestled in the olive groves of Finikounda in southern Peloponnese, Villa Ypsilon by LASSA Architects redefines sustainable summer living. Designed by architects Theo Sarantoglou Lalis and Dora Sweijd of the London and Brussels-based LASSA Architects, this 1,614 sq ft residence stands out for its innovative Y-shaped green roof that merges fluidly with the terrain—blurring the line between architecture and nature.
