The 140° residence is located on the southern side of Milos, in the area of Chalakas. The main architectural concept arises from the tracing of two stone walls forming a 140-degree angle. This gesture follows the natural curvature — the topography — of the landscape, while ensuring optimal orientation and uninterrupted sea views from all main living areas.

Between these two walls, enclosed interior spaces and open-air courtyards alternate, creating a rhythmic sequence of solid and void. The composition is structured in two parts: the main house and an independent guesthouse. Although functionally autonomous, the two are conceptually unified through the shared geometric gesture, forming an architectural whole that seems to emerge organically from the landscape.

The communal indoor and outdoor spaces are placed centrally, acting as a zone of gathering and connection among all functions. The private spaces are positioned on either side — to the east and west — providing a greater sense of privacy for the residents.

At the rear of the building, a pergola-covered outdoor parking area is arranged. The main entrance is located at the curve of the central axis, reinforcing the geometric intent of the composition.

To the east of the entrance, lies the kitchen and dining area, directly connected to an outdoor dining space designed as a sheltered courtyard. To the west, the living room opens out to the view and features a shaded outdoor lounge under a pergola. Further west lie the wc, the staircase leading to the underground utility spaces, a bedroom with an en-suite bathroom, and the master bedroom, which has its own courtyard, pergola, and outdoor jacuzzi.

The guesthouse, located to the east, includes two independent rooms with private bathrooms and a small shared kitchenette. In front of the guesthouse and the living room, a communal terrace with pergola and seating area is laid out. Extending from the terrace towards the sea is a 120 sq.m. pool, whose shape mirrors — in reverse — the layout of the residence, creating a conceptual “embrace” around the outdoor space. Further south, on a natural plateau, a shaded open-air gym area is designed.

The material palette includes exposed stone masonry for the primary walls, plastered stonework in earthy tones for secondary elements, rectangular stone paving for both interior and exterior floors, and cement mortar for built-in elements. The pergolas are constructed from corten steel frames, chestnut wood, and reed, while the window frames are slim-profile in dark grey. The roofs are planted, both to soften the visual impact of the architecture on the landscape and to improve the building’s energy performance.

The architectural intention of the project is a gentle, discreet intervention that harmoniously blends respect for the Cycladic landscape and terrain with the needs and comforts of contemporary living. Residence 140° combines functionality, seamless integration with nature, and understated luxury — proposing a thoughtful and modern way of inhabiting the Cyclades.
