In Liefering, a poor district of rich Salzburg City with three times more unemployed, one out of three people is under 19 years, creating a “street corner scenario”. A private initiative saw the problems, organized solutions and raised funds to create a Kids & Youth Center. The construction site was a neglected but central playground of 1050 sqm. The winner of the architectural competition was Thomas Forsthuber, Salzburg. His project created a cubage of 3144 cbm, a floor area of 720, a built-up area of 530 sqm and was built in 2000-2001. The building symbolically transforms the neighboring “boxes” into an amorphous, exotic body meant as a “shovel” to scoop kids from the street into it and as a protected, multipurpose activity space. With its stainless steel surface, the body reflects day- and streetlight. Exterior space is usable, the rooftop accessible and with a basketball court. Several entrances lead in, an outside tunnel and basin, an inside network of ramps, stairs and rooms encourage activity – individual and social. The organic floorplan is an antithesis to rectangular schools and housing. All age groups, boys and girls have their territories, ample glass panels offer vistas and social contact. Following user participation in the planning phase, the realized building is long-lasting (steel, aluminium, reinforced, fair-faced concrete), but open for user ideas, not overfurnished or functionally fixated. A full-time social worker and volunteers run the house which provides open access afternoon to evening. In the winter semester of 2002-2003, a group of Salzburg psychology students did a post-occupancy evaluation (POE) of the building under the supervision of the second author. For the POE, eight user observations (time samples) and nine interviews (with children/juveniles, staff and neighbors) were done in November with a seasonal focus on indoor activities. It was found that every second user was over 14 years old, one third were in the age group 10-14, 15% 6-10 years. Visiting girls prevailed under age 10, fell under 50% at 10-14 and nearly vanished over 14 years. The spatial diversity offered appropriate niches for different user interest groups. For the primary school visitors, the climbing wall was most popular (with two girls for every boy). Visitors over 14 preferred the central recreation room, the “bar” and the computer corner. The 10-14 age group was found both in the kids and youth areas. Most activities were social and interactive with the exception of a few bystanders and computer users. Four interviewed children/juveniles said they had found the institution by word of mouth and knew some of the visitors here. Friends were met both here and somewhere else. The weekday program was preferred, the weekends were “dull” because of few other visitors. Compared to their time out sitting on supermarket trolleys or with homeless people in the park the center did make a difference. Three staff members said that the local schools were important for first contacts with the clients. Special interest groups were the girls and the computer fans, the rest was “moving through the house”. Social problems were minimal (minor vandalism and damage, verbal conflicts). Parent contact was more intense with children under 12. Neighbor problems about noise had calmed down over time. An unsolved problem was the “hanging around” of kids outside the official opening hours of the center. Two neighbors were asked about their opinions. They found the design of the house “provoking”, but approved of its social function.
