A spruce forest, a slope, views of giant tree trunks, a pit left after an old building, birds, deer, and flickering sun rays. Below, the surface of a lake. The access road lies at the upper edge of the plot. From the street, the house appears single-storey — invisible and small; from the garden, it becomes two-storey — open and large. Cars park on the roof. The massing of the house follows the slope of the terrain and the client’s spatial requirements. The central staircase space (the “torso”) connects the western and eastern wings — the day and night zone. The main concept is a visual axis and descent into the forest landscape. Green and red as complementary colors. The house — an organism — becomes part of the forest.
Villa Jevany is located in a densely wooded part of the village with solitary family houses. Originally forest plots are long, bordered by an upper forest road used mostly by locals, and a lower path running along the ponds, visually shielded by mature trees. For one of these exceptional sites, the brief called for a modern house with an industrial expression.
The sloping terrain descending from north to south, with access from above, was crucial for the design. One of the key decisions was the precise placement of the building on the plot, which is relatively large. Remnants of the original house were removed, leaving a pit with a height difference of about 3.6 meters from the road. Mature trees stand up to ten meters below the building site and form a striking phenomenon — they rustle, move, and rise like sculptures toward the sky. A setback of nearly five meters from the adjacent semi-street creates a generous entrance area and parking on the roof terrace.
The orientation of the house responds to cardinal directions and views. It opens to the south and toward the forest, while remaining closed to the north and the street.
From the northern upper side, the house is embedded into the slope. From the street, it appears single-storey and almost invisible; from the garden, it is entirely different —tall, glazed, generous. The core idea is the visual axis and descent into the forest landscape, as if stepping from the carport into another world.
The central staircase hall (a kind of solid backbone of the creature) connects the western and eastern wings.
The house can be read in five basic operational levels:at street level,the covered parking,central entrance space, and a bright area with a study; at forest level,the day and night zones.
