SITUATION AND CONCEPT
In order to reach the area, many obstacles have to be overcome. This should change. The lack of access to the water (Wertach), the lack of networking within the neighbourhood - the Zeuna-Stärker area is an important - still missing - building block to solve many of the neighbourhood's problems. New high-quality open spaces with attractive offers, diverse forms of living, atmospheric spaces - defined spaces in general - all this is brought about by the development of the area. And our project offers these new, diverse spaces.
We see great potential in the preservation and conversion of the existing buildings and halls, in the connection to the park in the south and in the special location for living with the connection to the green space of the Wertach. On the basis of these development possibilities, we have developed a multi-layered project that, on the one hand, preserves and emphasises existing special features and, on the other hand, creates a network with the surrounding neighbourhood and thus supplements spaces that are lacking there.
Two directions stand out in the context, an industrial direction and one coming from the city. The industrial direction is based on the hall structure that follows the sloping Hettenbach. The more orthogonal neighbourhood structure is formed by streets and buildings in a north-south direction and cross streets in an east-west direction. The confrontation with these directions forms the basic structure for the project.
Another striking feature is the division of the perimeter into two parts. In the upper part, where the school is located, there is plenty of space to arrange buildings. The surrounding area and the structure of use are somewhat less heterogeneous and more occupied by housing and residential uses. In the south, on the other hand, a much more open space dominates with the existing hall buildings, the insurance building and the park. Here one has more of an image of the dissolved city before one's eyes. The northern part is more reminiscent of the classic European city. Here there is the possibility of connecting to the existing road network. There is little dense residential development with great potential for redensification, and one would like to see more urban contained spaces. Thus, our proposal shows a kind of bifurcation of the development, into a more enclosed part (courtyards and panes) in the north and a more loosened part (point houses, high point and converted halls) in the south. The transition between these two structures is fluid - around the existing halls, one development structure replaces the other.
NEIGHBOURHOOD, SPACES AND PLACES
In the north, the development with the existing buildings on Schönbachstrasse and Ahornstrasse forms residential courtyards and defined public spaces. In the centre, a larger square is created that could be used temporarily as a market place and on the west side of which a small café is planned. This square is located at the important cross-connection across Donauwörtherstrasse - past the Edeka - to the waterfront. It is a stepping stone in both directions, a special place in the middle of the neighbourhood. From here, a traffic-free or heavily calmed area leads north towards the schools. This connection links the sports fields, the school and the day-care centre in the north.
The development forms loose residential courtyards with detached disc-like point houses, which relate to the two high points in the north and offer good residential quality with reference to the greenery.
In the south, around the halls, there are point-like structures and a 14-storey high point that relates to the building on the corner of Donauwörtherstrasse and Dieselstrasse. These buildings form - with the halls and also with each other - clearly defined plaza-like spaces with different qualities: a landscaped square around the turbine with urban gardening, a stepped area to the Hettenbach, a workshop around the old halls with workshops/studios, a trendy sports hall with gastronomy and a beer garden and finally, around the three point buildings in the park, an intimate residential courtyard as a meeting place.
USES AND MIX
As the supply is described as sufficiently available, we propose mainly residential uses. The preserved halls can be used for special programmes due to their spatial characteristics - their position in relation to each other and thanks to their large volume. Here we propose uses from which the larger surroundings or the entire city of Augsburg can also benefit. In the largest northern hall, trend sports will find their place, e.g. skate park, bouldering hall, indoor sports and playgrounds, trampolining, as well as a larger gastronomy with beer garden. The desired urban gardening can be found in the area around the turbine and can also use storage areas in the hall.
The two smaller buildings/halls could be used for workshops on the ground floor; so-called Fab Labs are conceivable, i.e. open workshops in which projects can be realised under supervision. Other possible uses include repair cafés, artists' studios or social projects. The upper floors could be used for studios or coworking spaces. This area should be highly activated and offer programmes throughout the day, i.e. it should radiate activity 24 hours a day.
Two integrated day-care centres are located in the north and in the south, each with a dedicated open space in the south. The point houses and the residential tower in the south are purely residential buildings. The courtyard buildings in the north are purely residential, except for a few possible uses on the ground floor around the square (café, bakery, insurance broker).
ORGANISATION AND ACCESS
The neighbourhood will be connected to the road network via a small spider in the west from Weiherstrasse via Schönbuchstrasse. The three residential courtyards are accessed from here via underground garages. The point houses in the south will be accessed via the southern end of Äußere Uferstrasse. Thus, the feared connection in the east-west direction is not necessary. All other "streets" are traffic-calmed and can be used temporarily for deliveries/moving or as escape routes/fire brigade.
The Äußerer Uferstrasse is car-free for long stretches, so the character to the allotments in the east, starting from the school in the south and almost to the park, is rather shaped by the open space and remains car-free (delivery, fire brigade rescue excluded).
Less sealed areas with a high quality of stay could be created here and used for communal activities, e.g. for playing boules or as picnic areas. Numerous connections with cycle paths and footpaths link the entire perimeter with the surrounding area.
As many good residential locations as possible are to be created with maximum relation to the green space.
The courtyard developments allow for very economical two- and three-flats. The subsidised flats are also integrated into these courtyards.
In the southwest, a noise protection type with front-mounted noise protection loggias is planned, as it is very likely that non-opening windows will be required here (TA Lärm applies if the turbine is not enclosed). This type of noise protection also provides noise protection for the buildings further south.
Along the sound emitting sources (Aldi, turbine) there are mostly closed buildings. The courtyard development protects the adjoining open spaces from noise. The orientation of the floor plans provides a good solution for noise protection. The flats are all through-roofed or oriented exclusively towards the courtyard. The rooms requiring protection are oriented towards the quiet courtyard side.
The point houses in the south are only affected by the ventilation systems of the insurance company and Aldi. If a suitable solution (enclosure) could be found for this, no further measures would be necessary. If necessary, the point houses are ventilated in a controlled manner or receive so-called Hamburg windows.
Enclosing the turbine house and the ventilation systems would simplify the whole situation considerably. We would strongly advise this. Also for the landscaped area (there is no requirement for open space when TA Lärm applies), an enclosure would bring significantly more amenity quality. For example, a climbing wall or a small kiosk could become part of this enclosure, adding further value to the open space.
ENERGY AND SUSTAINABILITY
The compact urban setting minimises heat loss from the residential development. Efficient routing of the utility network is ensured. The sloping forms lead to an increase in the south-facing proportion of the buildings. The roofs are intended as flat roofs, which allow for possible extensive greening, but also the use of photovoltaics.
The openly shown water management via retention troughs shapes the character of the neighbourhood and should also be thematised in the buildings. The use of rainwater is planned. In addition to watering the gardens and flushing the toilets, rainwater can also be used for washing clothes.
