The first stage (2003-2004) involved developing the awarded proposal guided by europan Austria, Vienna council and city experts.The architects worked together with these stakeholders on some aspects related to the implantation of the project in the plot area and the relation with the neighbourhood. Although significant changes related to the uses were proposed, the main concept of the project had been kept during the whole process.
After this stage, in 2005, site owners (city of Vienna) and competition organizers decided to engage a competition between developers. The team was actively involved in the progress of this stage by preparing a project implementation with plans, schemes, guidelines and selection criteria for the competition.
In 2006, ÖSW was selected through this developers competition to develop the Europan project and the team started a new stage developing ÖSW ideas together with their own ideas in a really tough process in which the architects overcame a lot of different situations. Continuous changes threatened the project during this endless phase, involving main uses variations as a hotel, a temporary houses zone, a cellars area, a huge supermarket, a 300 employees enterprise, a 2-level youth hostel, a ground floor car park, a central park, etc.
After four years of common work, the Austrian architects team partner with the Spanish Europan team, was substituted by the client (in the first stage their partner was Vasko+Partner ingenieure). “Mischek gmbh” was chosen to join the Europan team. Together they continued a tortuous way with plenty important regulations variations, constant client criteria changes… in short, an endless 6-year period full of vicissitudes while trying to keep this project going.
After all this work, in 2012, client approved draft design and it was possible to go through the planning permission phase with the city of Vienna and all the different actors involved. Everything turned out well, and fortunately the project got the planning permission in the first attempt. In 2013-2014 the architectural project has been completed and has been redefined and optimised in several ways: shape, finishes and project concept to answer to economic requirements. It was a very hard work due to the superimposition of opposite levels of information that were constantly redefined and centralized in a complex and heavy technical document. By the end of 2013 the client took the final decisions and the project was finally completed for implementation.
