The project concerns the design of a two-apartment residential building located in the center of Kifissia, on a busy urban street with limited visual connection to the public realm.

The main design strategy responds to the need for privacy and acoustic protection. The building is conceptually “turned” inward: the staircase is positioned along the street façade, forming a protective buffer, while the primary living spaces are oriented toward the interior of the plot. This inversion allows the apartments to establish a direct relationship with the south-facing garden, ensuring calmness, natural light, and visual continuity.

The spatial organization follows this orientation logic. Living areas and master bedrooms are placed on the south, opening through large apertures, while service spaces and circulation are located on the north. A lightweight metal screen is introduced on the street façade, filtering views and light, while maintaining privacy.

The building accommodates two distinct housing units. The ground-floor apartment (60 sq.m.) is compact, containing two bedrooms and direct access to a private outdoor space. The first-floor apartment (100 sq.m.) is more expansive, with two bedrooms, a generous living area, and an attic workspace connected to a roof terrace.

The volumetric composition is defined by three interlocking grey volumes, emphasizing contrast and depth—a strategy often used to enhance spatial legibility and hierarchy in architecture . Materiality reinforces this approach: wood defines the interior spaces, while cement mortar and dark metal elements shape the exterior surfaces and shading systems.

Internally, a suspended metal staircase with wooden treads connects the living space to the attic, introducing a vertical spatial continuity. A custom wooden bookshelf forms the boundary of the attic level, functioning simultaneously as storage and a protective element.
