A glazed wall, a high ceiling, and a kitchen island in natural stone set the tone from the first step inside. The living space reads as one open volume, with the lounge, dining area, and kitchen placed in a clear sequence rather than boxed into separate rooms. In this transparent interior, the lines stay restrained, the surfaces stay quiet, and the view becomes part of the composition. The apartment uses that openness to frame light, movement, and a strong sense of depth.

Double-height living space with a hidden route upstairs

The duplex interior is shaped around a double-height open living space, where the lounge rises into the full ceiling height. That vertical void gives the room its main gesture. Instead of a visible stair dominating the scene, a hidden staircase leads from the open area toward the private rooms. Office, master bedroom, children’s room, guest room, and three bathrooms sit above and beyond the living zone, turning the plan into a sequence of layers rather than a single open floor.

What makes the transparent interior work is the way the transition between public and private zones stays almost understated. The open living space remains visually light, but it still has direction. You read the apartment through openings, thresholds, and changes in scale. The result is less about spectacle than about controlled exposure: a room that opens widely, then folds back into calmer, enclosed areas when the stair takes you away from the main volume.

An open kitchen anchored by stone

The kitchen holds the room with a natural stone island and clean-edged joinery. It is not pushed into the background. It sits directly inside the open living space, so the eye moves from the stone surface to the oak parquet and back to the windows in one sweep. The material contrast is understated: stone for mass and definition, oak for a softer base underfoot, and pale wall surfaces that keep the whole zone from feeling heavy.

Across the kitchen wall, custom joinery sets up recessed niches and crisp horizontal lines. The built-in storage does more than hide equipment; it edits the wall. Small openings, flush fronts, and integrated details keep the room visually calm while still giving it structure. The open kitchen natural stone area therefore feels precise without becoming severe, and the surrounding cabinet work supports that clarity rather than competing with it.

Material moves that keep the room quiet

Natural materials repeat in measured ways. Oak parquet runs through the living areas and softens the geometry of the apartment. Stone appears again in the kitchen and in the bathrooms, linking the spaces without forcing them into one theme. The palette stays close to sand, beige, grey, and off-white, with only small shifts in texture to mark one zone from the next. Because the surfaces are restrained, the light on them carries the rhythm of the day.

Large windows, layered views, and sea-facing light

Large windows do much of the visual work here. They widen the open living space and let the apartment borrow from the horizon beyond it. The source material refers to a 180-degree view over beach and sea, and the interior responds to that with pale tones and materials that do not fight the outlook. Curtains frame several openings, softening the glass without closing it off. The room stays transparent, but never bare.

The window wall also gives the apartment a layered reading. You see the interior first, then the glass, then the distant view. That sequence is reinforced by the open plan, where the seating area, dining table, and kitchen all sit close to the facade of light. The effect is not decorative. It is spatial. The transparent interior lets the outside line the room, while the calm neutral palette keeps attention on the proportions of the opening rather than on a strong color statement.

Custom joinery and niches that hold the plan together

Across the apartment, custom joinery provides the quiet edge that keeps the layout sharp. Cabinets sit flush, niches are carved into walls, and details are folded into the architecture rather than applied on top. In one view, a dark linear element cuts across a pale wall panel; in another, an inset opening and textured stone surface create a more tactile moment. These moves are small, but they decide how the eye travels through the duplex interior.

The same restraint appears in the dining zone, where a round table, a suspended lamp, and wall shelving create a separate scene without breaking the overall openness. The furniture does not crowd the room. It gives the space a second tempo after the larger gestures of the kitchen and windows. That balance between open living space and smaller fitted elements is what makes the apartment feel composed from within, not assembled from separate rooms.

Bathrooms that continue the material language

The bathrooms continue the apartment’s neutral register with stone, light cabinetry, and pale tiled surfaces. A walk-in shower is visible in one of the image details, and a vanity with white fronts and a stone top appears in another. These rooms are not treated as isolated statements. They extend the same natural materials into smaller spaces, where the surfaces become more intimate and the light more enclosed. The finish stays pared back, but the textures remain distinct.

Because the apartment already works with openness and contrast, the bathrooms can be quieter. Their role is to slow the pace after the larger living volume. Stone, tile, mirror, and cabinet fronts stay close in tone, yet they still create enough variation for the room to read clearly. The transparent interior therefore reaches all the way through the plan: from the double-height living area to the more contained rooms at the back.

The overall impression comes from restraint rather than accumulation. A transparent interior can easily become visually thin, but here the materials give it weight: oak parquet underfoot, stone at key surfaces, glass at the perimeter, and custom joinery that shapes the walls. The apartment keeps its openness, yet every zone has a clear edge. That is what gives the duplex interior its measured pace and lets the view, the light, and the room proportions stay in focus.

Sources note the involvement of trades for parquet flooring, painting, electrical work, sanitary fittings, curtains, furniture, and lighting, which helps explain the precision of the finished spaces. The result is an open living space that relies on disciplined detailing rather than ornament. From the hidden staircase to the stone island and the framed windows, the apartment builds its identity through structure, surface, and light.
