Gemeinwohlorientierte Stadt. Urbanes Wohnen in Erlaa
Master's thesis summer 2020

Published by the Institute ofDesign and Urban Planning (Prof. i. V. Andreas Krauth/ Verena Schmidt)

In the summer semester 2020 we are looking towards Vienna.
The development area “In der Wiesen” borders the residential park Alterlaa to the south. Parts of the area are already built on or currently under construction. The master thesis focuses on the largest sub-area “In der Wiesen Mitte” (approx. 29 ha). This area has the potential not only to fill gaps, but to develop a coherent neighborhood with a strong spatial, programmatic and design vision.
The task is the context-specific design of a dense residential quarter with complementary uses from the commercial, social infrastructure and agricultural sectors. The urban design should be in keeping with the scale of the surroundings and develop an appropriate relationship between open space and buildings. Qualities are to be created that benefit many people and promote positive coexistence and togetherness. This refers both to the overall scale of the neighborhood and to specific building and open space types.

The design aims to meet the increasingly complex housing needs of people. In Vienna Liesing, a vital environment was found, which is already well developed in large parts. The designed area should become the new center and important account point for the network of public spaces of Liesing and thus activate the entire region. Axially, different public spaces, whose use is all agricultural, will be arranged.
This agricultural model is extended by a community model in whose development there are more and more activity possibilities. Thus, there are not only farmlands, supermarkets and restaurant, but also interest groups and research centers in the community. Thus, the inhabitants get the opportunity to actively participate in the future development.
In four development phases, both the agricultural land and the community activities will be cultivated and intensified. In the first phase, open farmland is offered for use. In the second phase, this is supplemented with greenhouses. In the third phase, there is a production center where people can find stores, community canteens, restaurant, etc. In the last phase, agriculture is thought of in the context of sustainable development and recycling. There is an agricultural experiment center, an exhibition center for new agricultural products and aquaponics systems. Furthermore, rooftop farms are operated that have solar panels and rainwater harvesting systems. At the same time, the functions of the central square become more complex as the community develops.
Housing types are characterized by communal space offerings. Public spaces and amenities are adaptable to meet the needs of the residents. The community way of life, is to develop not only in agricultural production, but also in many related activities: Agriculture, living and more.

The design “Erlaa Bunt Verbunden” links existing structures and creates new offers for the common good. The central element is a large neighborhood park that expands existing open space offerings and forms a continuous green connection to the subway station in the south. Four new sub-neighborhoods are arranged around the neighborhood park, which are given different characters and focal points through different uses. The creative quarter forms a central building block with new access to the elevated railroad. Here, numerous cultural offerings invite visitors to participate and linger. In the north of the creative quarter, the educational campus is directly adjacent, which forms synergies with the surrounding residential development through its loose building structure. The design is characterized by differentiated open space offerings. In addition to the park, an active mile is located to the east of the education campus, which offers numerous sports opportunities for all generations and encourages people to move. The neighborhood promenade, which runs from east to west, will feature a variety of commercial spaces and services on the first floor. The central strip serves as a consumer-free recreation zone and meeting area for all. Parallel to the south of the neighborhood promenade runs the garden strip, which is intended to invite residents and visitors to garden together and, in addition to a meeting place, also offers a place for self-sufficiency.
