Interiority and design details.
On the ground floor, we created spaces with an emphasis on privacy, such as the en-suite bedrooms and the guest room featuring a unique loft. Natural materials and minimal lines compose an atmosphere of tranquility that acts as the perfect retreat.

TOUBATI _ design

The revival of "Batis Bakery" In Kato Chora, Serifos, a building with a history starting before 1885 is transformed. Historically known as a grocery store and bakery, the original structure expanded over the years. Our goal was to unify these spaces into a modern two-storey house, maintaining a minimal aesthetic that respects and blends seamlessly into the Cycladic landscape.

Terra - H | Privacy sculpted in curves. In the master suite of Terra-H, the architectural language shifts into a more intimate scale. The radial timber beams and hand-applied textures provide warmth to the geometric rigor, creating a sanctuary where light and shadow play across soft, organic forms.

Terra - H | The Funnel Effect. The main living area is designed as a fluid volume that draws the eye toward the Aegean blue. By using a consistent palette—from the pebble-infused cement floors to the earthy plaster walls—we blur the lines between interior and exterior, creating a space defined by light and natural continuity.

Terra - H | Architecture as an extension of the earth. At Terra-H in Serifos, the subterranean structure and raw stonework allow the residence to dissolve into the Cycladic landscape. The signature curved facade acts as an organic gesture, balancing the boundary between solid ground and open horizon.

OUTLINE _ under construction

New cave house in Ganema, Serifos — designed to blend into the natural slope behind an existing stone wall. Two parallel facades, filtered light, and a planted roof bring the landscape into the architecture.
Sliding glass,warm wood, and soft light define the interior, while the outdoor spaces flow naturally between sun and shade.
