Open sightlines set the tone from the first step inside. The double-height volume gives this penthouse a loft-like character, while warm wood flooring, dark cabinetry and pale structural lines keep the interior readable at every turn. The layout was shaped from the earliest drawings, with the rooms arranged in close dialogue around one remaining load-bearing wall. That early involvement is visible in the way the spaces move into one another without losing definition.

Double-height volume and open sightlines

The high void is more than a dramatic gesture. It pulls light deep into the apartment and lets the upper level stay present in the background, even when you are downstairs. Large windows widen the view, and one square opening acts almost like a framed picture within the room. From the lounge, the interior looks outward in several directions, so the penthouse interior design is carried by routes, openings and long lines rather than by separate closed-off rooms.

The material palette supports that openness. Wood floors bring warmth underfoot, while light walls and darker built-ins hold the volume in check. Italian-inspired kitchen elements appear as part of the overall composition, not as isolated showpieces. The result is an open-plan penthouse where the kitchen, dining area and living space stay connected through proportion, finish and the rhythm of the architecture.

The spiral staircase as room divider

The spiral staircase is the clearest marker in the main living area. It catches the eye immediately, but it also does practical work. Set between the dining area and the living room, it divides the plan without closing it off. Its curved shape softens the straight lines around it, and the white surround with timber treads makes the stair read almost like a sculptural object inside the room. In a space this open, that kind of separation matters.

Seen from below, the stair works with the upper void and the adjacent glazing to keep the interior visually active. It gives the loft-style interior a center of gravity. The staircase also helps pace the movement through the apartment: from dining to lounging, from the main floor to the upper level, and from the inside out toward the terrace. The room divider is not decorative in a superficial sense; it is part of the way the apartment is planned.

Dining beside the west-facing opening

The dining table sits near the western side of the apartment, where wide folding doors open the full width to the terrace. That detail changes the use of the room. The table becomes a place that can stretch outward when the doors are open, with the threshold almost disappearing during the warmer hours of the day. The timber tabletop gives the dining area weight, while the surrounding glazing keeps the space tied to the outside and to the changing light.

Because the table sits close to the opening, the interior reads in layers: kitchen behind, dining in the middle, terrace beyond. That layering suits the rest of the penthouse interior design, where one space is never fully cut off from the next. The open-plan penthouse gains its ease from these overlaps rather than from broad gestures.

Kitchen lines, dark fronts and warm wood

The kitchen is defined by darker fronts and a disciplined run of cabinetry that reaches up to the ceiling. In the images, the fronts sit against lighter architectural surfaces, so the kitchen registers as a distinct band within the larger room. Linear lighting above the work zone reinforces that line. The island and bar seating create a place to pause without breaking the room into smaller fragments, and the kitchen retains a clear relationship with the adjacent living area.

Warm wood interior details temper the stronger contrast. They appear in the floor, in the dining table and in the walnut surfaces used elsewhere in the apartment. That repetition keeps the project from feeling fragmented. The custom interior design is most apparent here: storage, working surface and circulation are aligned so the kitchen supports daily use while remaining visually calm inside the double-height penthouse.

Material contrast that stays consistent

Rather than relying on ornament, the apartment uses material shifts to mark change. Dark fronts, pale walls, timber flooring and stone-like bathroom finishes each do a different job. In the living area, that means the eye moves easily from one zone to another. In the kitchen, the contrast gives the cabinetry a crisp edge. Elsewhere, walnut and other natural finishes add depth where the apartment needs it most. The effect is quiet, but it is carefully controlled through the interior architecture.

Bedroom and bathroom spaces with tailored storage

Downstairs, the master bedroom continues the restrained palette. It is paired with a walkthrough bathroom that brings together a solid walnut vanity, a walk-in shower, a toilet and a full run of fitted wardrobes. The joinery runs the length of the wall, turning storage into part of the room’s architecture rather than an afterthought. The wood surface gives the bathroom area a denser note and links it back to the rest of the penthouse interior design.

Images of the bathroom spaces show stone-like finishes, glass shower enclosures and clean-lined details that keep the surfaces legible. A round mirror appears in one of the rooms, while the bedroom includes a textured feature wall that gives the sleeping area a stronger backdrop. These are not separate decorative moments. They sit inside a broader custom interior design strategy that keeps each room tied to the same material language.

Upstairs rooms and the roof terrace

The upper level holds a guest bedroom, a large bathroom with a freestanding bath and access to the roof terrace. Here, the apartment opens out again after the more enclosed lower rooms. The terrace extends the living area upward, while the broad view makes the upper floor feel different in scale from the level below. The project never loses the double-height penthouse character, because the visual relationship between the floors remains visible.

Even on the upper floor, the layout feels measured rather than crowded. The bathroom uses a larger footprint, and the freestanding tub gives the room a clear focal point without adding clutter. From there, the roof terrace finishes the route through the apartment with open sky and long sightlines. It is the last shift in a sequence that starts with the staircase, passes through the dining and living areas, and ends high above the main volume.

A penthouse shaped by layout, not by display

What stands out here is the discipline of the planning. The interior was developed from the first drawings, and the rooms were set with a clear understanding of how the apartment would be used. That is why the penthouse interior design feels settled without becoming static. The stair, the wide openings, the timber surfaces and the fitted storage all support the same idea: a loft-style interior that uses height, light and material contrast to define space.

The project also shows how interior architecture can carry the experience of a home without overloading it. Each zone has its own function, yet the apartment still reads as one continuous sequence. From the living room to the terrace, from the bedroom to the bathroom, from the lower floor to the upper level, the details stay connected through proportion and finish. That consistency is what gives the open-plan penthouse its strength.
