The curved green roof is the first thing the eye reads here: a low, planted surface that rises on the south side and gives the house its clear profile. Beneath that line sits a passive home with curved green roof, designed around thick insulation in the walls and roof, smart ventilation and triple glazing. The result is not announced with technology on display, but with a quiet exterior made of glass, timber and a roof that shifts the volume inside.

Thick insulation, controlled air and light-filled rooms

The passive home with curved green roof is built to reduce heat loss through extra-thick insulation in the walls and roof. That part of the story stays hidden, but its effect shapes the way the interior is used. Smart ventilation keeps air moving without relying on a classic central heating system or stove. Triple glazing supports that approach and allows the large window openings to stay visually light, even where the glazed surfaces are generous. The building reads as restrained from the outside, yet the openings suggest a room that is intended to work with daylight rather than shut it out.

What stands out in the images is the contrast between the white window frames, the dark timber elements and the broad panes of glass. The house does not rely on ornament. Instead, the rhythm comes from the placement of openings, the horizontal lines of the facade screens and the way the roof edge cuts across the volume. In several views, the glazing stretches across more than one bay, giving the rooms a measured openness while the sun-shading devices hold the composition together visually.

A roof that changes the room beneath it

The curved green roof is more than a planted cap. On the north side it stays lower, while on the south side it lifts and creates a taller living room with a mezzanine. That change in height is visible in the silhouette before it is experienced inside. The roof line bends the volume instead of flattening it, and that simple move gives the house a clear asymmetry. The planted surface, formed with sedum roof planting, softens the outline and keeps the long roof plane from feeling heavy against the rural setting.

From the exterior, the green roof also reads as a continuous material field rather than an isolated feature. Its texture changes with the season, moving from one shade to another across the sloping curve. The planted roof sits above the timber elevations and the white frames, so the architecture feels anchored by a living top layer. In the photos, the curved green roof is the dominant gesture, visible over the entry side, along the side elevation and across the long roof plane that runs over the glazed sections.

Inside, the rise on the south side makes room for height

Because the southern roof edge lifts, the main living area gains vertical space and a mezzanine level. That extra height is not decorative; it changes how the room receives light and how the volume is read from within. The taller section also gives the glazing more room to work, especially where the south-facing glazing takes in winter sun. The house uses that exposure deliberately, letting the room depth and the higher ceiling work together rather than competing for attention.

The passive home with curved green roof depends on this kind of spatial adjustment. A narrow roof profile at one end and a lifted roof at the other create a section that does real work. In the images, the house appears low and stretched, then suddenly opens where the roof rises. That shift gives the interior its clearest moment: a living zone that feels tied to the roof shape instead of being fitted beneath it.

Winter sun in, summer heat out

Solar orientation is central to the design. In winter, the house collects as much sun as possible through the large south-facing glazing, making the most of the open glass areas. The south side is therefore not only the brightest part of the house, but also the side where the elevation is asked to do the most. The glazing is paired with the roof geometry, so the opening strategy belongs to the shape of the building rather than being added afterward.

In summer, the same side needs protection. Roof overhangs limit direct sun, and automatic shading adjusts the amount of light entering the rooms. These devices are visible in the facade composition as horizontal lines and moving layers across the windows. They keep the glass from becoming a single exposed surface. In this passive home with curved green roof, the shading is part of the architecture, not a separate technical fix. It follows the long horizontal proportions of the house and reinforces the calm, linear reading of the elevations.

Glass, timber and shutters give the house its rhythm

The exterior is carried by a combination of timber cladding, white frames and long strips of glass. In some views the timber has a dark tone; in others it shifts toward a warmer brown. Horizontal shutters and facade screens break up the larger openings and give the wall surfaces a clear rhythm. A brick section appears in the material mix as well, adding a heavier note beneath the lighter window bands. These elements sit neatly under the curved roof, so the house reads as composed from simple parts rather than decorated with additions.

Close-up images show how the roof overhang casts shadow across the window line and how the lamellae work against glare. The detail is modest but precise: a large pane, a white frame, dark slats, then the edge of the roof above. That sequence repeats in different parts of the building, which is why the passive home with curved green roof feels consistent from one elevation to the next. The moving shades and fixed slats give the windows a second skin without hiding the structure behind them.

Seen from the side, the house stretches out in a long horizontal line, with repeated openings and shutter elements running beneath the planted roof. The entry and terrace areas sit close to the ground, while the raised south side is reserved for the larger room volume. The landscape remains visible around it, but the building keeps the eye on the roof curve, the glazing and the timber surfaces. That is where the project’s identity sits: in a careful section, a planted roof, and openings that are shaped by sun rather than by display.

Even at a distance, the silhouette makes the idea legible. The curved green roof is what ties the elevations together, while the white window frames and dark timber pieces sharpen the composition underneath. It is a passive home with curved green roof that relies on visible decisions: south-facing glazing for winter gain, roof overhang for cooling in summer, automatic shading where the sun is strongest, and a roof that rises to make space where the plan needs it most.

The result is easy to read in the photographs. A planted roof traces the top line, horizontal shutters mark the windows, and the timber cladding gives the house a grounded surface against the surrounding greenery. The building does not try to disappear, but it also does not shout. Its details work quietly: glass catches the light, slats break it, and the roof curve finishes the composition with a single, continuous gesture.
