Facing an open green space on the outskirts of Stockholm, the 79 & Park apartment block completes an edge of the existing city and establishes a transition between building and nature. BIG proposed an imaginary nature that redesigns artificial space and interprets a constantly growing trend: experiencing nature as a visual transposition of wellbeing by generating an artificial fragment of nature, designed to last and perhaps even replicate elsewhere in the city. The base module of the entire complex, 3.60 x 3.60 metres, was used to create a square grid rotated 45 degrees with respect to the edges of the lot. This rotation of the cells was combined with the controlled extrusion of the units. Through these moves the three-dimensional grid articulates the internal spaces of the flats, orienting openings to guarantee optimum exposure to the sun and modulating the common areas on the ground floor and the external envelope.
