This house was built in village on a former agricultural estate, replacing two old chicken coops that once stood on the site.
A chicken coop structure is traditionally based on the principle of two sloped roofs that are detached from each other to allow ventilation and the release of hot air. This unique form served as inspiration for the design of the new building. The concept of ventilating the structure by separating the roofs was preserved in the new house through electrically operated windows that create a gap between the two roofs, facilitating the release of hot air.

The combination of two roofs—one higher and the other lower—also influenced the interior planning and design. Beneath the high roof, an open-plan space was created for the living room, dining area, and kitchen. Meanwhile, under the lower roof, the three bedrooms and service areas were placed, benefiting from more intimate proportions and spatial definition.

The roof was designed with a ventilated cladding system, where the wooden cladding is detached from the structural roof, creating an air gap that enhances thermal insulation, protects the waterproofing layers, and conceals the gutters, resulting in a clean and cohesive aesthetic.

Unlike the common construction method in Israel, which primarily relies on concrete, this house features a steel frame structure which was prefabricated and delivered to the site as pre-assembled wall sections. Compared to concrete construction, the steel structure enabled superior thermal insulation, larger openings without supporting columns, greater flexibility in the building's layout, and increased earthquake resistance.

The thick walls, some reaching up to 80 cm in depth, provide effective shading for the windows and also house air conditioning units, rainwater drainage channels, window shutter boxes, storage niches, bookshelves, and even built-in planters. This integration results in a clean and minimalist exterior appearance.

The maximum permitted building area was 160 square meters, a relatively modest size. To enhance the sense of spaciousness, the entrance hall, living room, kitchen, and dining area were designed as a single open space with a high ceiling and large windows facing a deck. The deck serves as a mirror image of the central space in terms of area, and the living room roof extends outward over it, creating the illusion that the house is larger than its actual dimensions.

A crucial aspect of the design was the strategic positioning of openings, wind directions, and shading elements. While the central living area faces south, the extended roof provides shade for the large glass doors and the seating area on the deck. The contour of the roof in this section was determined based on a shading analysis comparing summer and winter conditions. In summer, the glass doors and seating area are fully shaded, while in winter, the lower-angle sun reaches up to four meters into the living room.

The color palette of the finishing materials remains consistent both inside and outside, incorporating shades of black, white, light gray, and wood, which softens the monochromatic scheme and adds warmth to the space.
