The steep, geometrically complex hillside plot initially discouraged most prospective buyers—despite its stunning location and panoramic views. But this couple had ambition. They enlisted architect Markus Mucha to evaluate the site's buildability. What he discovered was promising: the land could accommodate an efficient, compelling design. Yet the solution wouldn't follow the crisp, right-angled aesthetic the architect and clients preferred. The compact 425 m² plot demanded something more inventive—a custom-designed home that reconciled building code requirements with their vision of contemporary, open-plan living featuring soaring spaces and expansive glazing.

The plot's geometry dictated the building's form, developed from inside out. A sunken courtyard sculpts the entry experience—accessed by a split staircase that wraps around the recessed garage. Because of the steep terrain, much of the structure sits below grade. Yet skylights, atriums, and gallery passages flood the interior with daylight and a sense of openness. Strategically positioned windows frame views of the surrounding landscape while screening out the dense neighborhood, creating serene living across three floors. Within the 235 m² of living space, distinct zones remain visually and functionally clear, yet connect fluidly through a rhythm of steps and openings. The dining area anchors the plan; from it, all other living and circulation spaces unfold. Inside, three materials dominate: warm oak surfaces, raw grey exposed concrete, and crisp white finishes—cast flooring, plaster, lacquer—working in concert. The oak floors and timber window frames infuse the home with warmth, while concrete planes introduce a counterbalancing minimalist edge. Entry flows through a coat-lined vestibule that tapers toward the stairwell and a window framing views to greenery. This level also houses a dedicated study, a sunken work zone, a small wine cellar, and utilities concealed behind a timber wall. The first floor centers on a sheltered terrace, buffered by the kitchen and living areas, connected to the interior via floor-to-ceiling glass sliding doors. A southeast-facing loggia with retractable glass walls extends the living space further. The attic accommodates a compact central pod—housing shower, sauna, and toilet—with the remaining space flowing into a bathtub, dressing zone, and bedroom opening to a rooftop terrace. From this height, the vistas are exceptional, and the true value of the challenging site becomes unmistakable: in the hands of thoughtful design, constraints become possibilities.
