Competition Hackstraße/Stöckachstraße Riehle Architekten Figure Ground Plan

Competition Hackstraße/Stöckachstraße

A city requires both continuity and transformation. Therefore, the urban concept for a former industrial EnBW estate carefully relates present and past connections with novel and future aspects. A balance of preservation and intervention, tradition and innovation forms a divers and dynamic new urban quarter by complementing dialectic opposites.

The combination of converting existing buildings and adding new structures, alongside the strengthening of superordinate urban routes define a masterplan, that connects the new quarter with the surrounding city and promises character and a new identity for the proposed living and urban spaces. Following their transformation, buildings worth to be conserved act as identity anchors for the new quarter. Precise new additions defined by clear typologies and spatial clarity complement an urban framework of high density and a diversified relation of build environment and public realm, of mass and space.  

The proposed masterplan suggests a hierarchy of greater urban connections and differently proportioned streets as well as a succession from public to private spaces. The historic Sickstraße will be reinstated in the city plan as a strong superordinate east-west connection linking the green park spaces around the Villa Berg with the Schloßgarten. A north-south connection negotiates the sloping topography and provides a good urban ventilation downhill. At the intersection of these major routes, a new public square is proposed in the heart of the new quarter with active edges and high amenity values. The inner sphere of the new block structures and the protected courtyards developed between existing and proposed buildings offer private and commonly used gardens and form a deliberate counterpart to the public realm around.      

The masterplan consciously alternates between subordinate and particular buildings to generate an agile piece of city made of background and foreground actors and a high diversity of mixed uses. The urban grain of the proposed buildings deliberately mediates between the large-scale structures along Cannstatter Straße/Neckarstraße and the typical small-scale structures within the Stöckach area.
