Set on a secluded hill, this residence emerges from the unification of two adjacent houses into an extended private mansion.
The design reimagines both architecture and atmosphere, merging structures, levels, and functions into a seamless whole. Interiors were restructured to create fluid connections between living, working, and leisure spaces, while the exterior was expanded with new facades, pergolas, terraces, and outdoor spaces.
On the inside, the reconfiguration opened new possibilities: the ground floor of one house now flows into the first floor of the other, creating expansive, interconnected living spaces. A floating kitchen anchors the social core, accompanied by a dining area, atelier, playroom, office, and guest suite — all suffused with natural light and uninterrupted views.
The lower levels evolve into a sanctuary of privacy, where the master bedroom with en suite bathroom, walk-in closet, and gym form a continuum of comfort and retreat with direct access to the outdoor pool and lounge area.
On the outside, the architecture extends into a sequence of experiences: an infinity pool blurring into the landscape, a sculptural suspended jacuzzi that hovers above the garden, shaded lounges and a summer kitchen with adjacent protected dining area for gatherings.
White volumes, wooden details, and Mediterranean planting frame the scene, balancing contemporary precision with a relaxed resort-like atmosphere.
Balancing robust architectural forms with a sense of retreat, the mansion is both a statement of contemporary living and a timeless refuge, where architecture, landscape, and light converge.
