Projects / Block Renewal Triesterstrasse

Urban Redevelopment Analysis

Renovating residential buildings and revitalizing public places would enhance the area significantly. Gutting and opening up inner courtyards could create attractive, quiet recreation areas in the urban area. Targeted demolition in conjunction with additions and attic conversions could be implemented without loss to usable areas.


With a series of public space measures, the area is to be further upgraded by measures to renovate the residential buildings. The ground level areas are made more attractive through more favorable spaces for shops and restaurants, as well as upgraded streets zones and open spaces.

Intersection Quellenstrasse/Knöllgasse

The plaza area is currently a landscaped island and barely usable. The proposal calls for integrating the road with the plaza area, to resolve the "island” nature of the space. The space is to be highlighted with a designed pavement area, and two buildings will be connected to enclose the plaza structurally.

Intersection Triesterstrasse/Davidgasse

The park in the area of the intersection is cut off from the residential building by the barrier effect of Triesterstrasse. This barrier could be broken by a coherent design, thus creating a visual connection between the park and the residential area on the other side of the street. The area in front of the park is to be made more attractive and noticeable. A new building is proposed for the corner which would close off the block and protect the inner areas against noise from the street. Floors are to be added to the Triesterstrasse 27 and 29 properties, which could be achieved with a bridge across Triesterstrasse.


Currently, the sidewalk on the side of the project area is narrow and is located directly next to the road, while the opposite side has a much wider sidewalk. In addition, there is a traffic island between the opposing lanes of traffic. The cycle path could be placed on the other side of the road here, and the sidewalk along with landscape strips next to the wall and the park minimized. The traffic island could be removed, thus gaining surfaces next to the residential building. The bike path should continue the whole length of Triesterstrasse and a parking lane with patches of trees should be placed between the bike path and the road. This would provide a visible barrier and reduce traffic noise. These measures would make the sidewalk next to the residential and commercial buildings far more usable for pedestrians.

Traffic Calming Measures – Crossroads/Blind Alleys

Three crossroads – which do not serve as main thoroughfares – are selected for traffic calming measures to eliminate traffic to or from Triesterstrasse. Re-positioning the sidewalk creates a larger area for pedestrians.

Cross-property Measures


The beginning of Triesterstrasse is undefined by the sprawling buildings, which are disconnected from one another. The plan proposes a canopy element to unify this area and provide greater safety for pedestrians.

Unpaved, Landscaped Courtyard

Densely built courtyards and paved open spaces are a problem throughout the area, resulting in a lack of private and semi-public green space for residents. The inner courtyards can be unpaved and measures to gut the courtyards can create attractive, quiet recreation areas in the urban space.

Gutting Courtyards

The dense development is typical of late nineteenth urban blocks. This results in very narrow, unattractive courtyards with very poor lighting conditions. The goal of this block renewal is therefore to ensure more attractive courtyards – and above all better lighting conditions – by gutting the courtyards. Effective measures include rooftop greening along with demolition of individual stories or even total demolition. Floor additions and attic conversions on the street side will balance any loss to usable space through demolition, and will replace substandard dwellings with high-quality terrace apartments thus increasing the quality and value of the real estate significantly.

Covering/Landscaping the Courtyard

Some courtyards are currently being used for commercial operations, so to reduce the related noise and achieve a visually appealing design, we propose covering and landscaping these areas. This creates terraced open spaces which can be designated as rooftop terraces for specific apartments. The surfaces interconnect make the yard an attractive usable space.
