As a city district, Vallastaden is unique in itself. Nearly 1000 residences have been built by 40 different developers – all in record time. The result is a vibrant urban district centered around its residents.
The Vallastaden model
Many of the innovative aspects of Vallastaden are direct results of challenging the way in which we traditionally build cities. Throughout the process, we have developed The Vallastaden Model – a new model for social planning. The model includes focus on social and ecological sustainability, quality criteria-based land sale instead of price based, and enabeling for a diversity of developers to be a part of the project. As a result of having such a large number of developers work together, Vallastaden has an architectural variety that is rare in most new city districts. Within a single block you will find a mix of detached houses, terrace houses, apartment buildings, student housing and commercial spaces. No single architect has designed two houses standing next to each other.
Ecological aspects where included in the planning by awarding developers quality points for ecological kits such as solar panels or solutions for returning energy to the grid. The city district was also designed encourage cycling and walking instead of traveling by car for example by locating the car parks in the outskirts of the district and by providing generousbicycle- and footpaths.
The infraculvert system
Because of the densely built urban environment combined with difficult soil conditions, it would have been difficult to lay pipes in the ground in the traditional way in Vallastaden. The solution was to install all the pipes for media – electricity, fibre optic internet, district heating, sewerage, water and automated vacuum collection – in an underground culvert system. Thanks to the concept it is possible to install, operate and maintain the pipes with less damage on the ground. Although the investment costs for the system are higher compared to traditional pipe laying, the life cycle cost is lower. A smart solution that is flexible for the future!
