PLAY places its main professional context in architectural competitions, where it has received numerous international awards. Among them are three first prizes in Europan which have clearly determined its focus on projects within the urban realm, taking the city as the main area of interest. Viena (E7) and Stavanger (E8) are developed as Urban Projects where residential use is a mere excuse to create a collective space (public and private) from public participation and management of urban controversies, and where such different cultures as the Austrian and Norwegian can recognize themselves. The importance of public space as a cultural fact evolves in the transformation of the proposal for Stavanger into a project ofUrban Space, a marine park, as an example of a designing attitude that PLAY also applies in other cases like Plaza de Séneca in Alicante or the awarded competition Mirador del Palmeral. . The latter, which becomes a mountain for the citizenship, adds this social condition to a project conceived for reactivating and bringing wealth to the Palm Grove of Elche, listed as World Natural Heritage. This is a clear case of Strategic Project that PLAY addresses in other cases such as the proposal for the new Guggenheim in Helsinki. Meanwhile, the research on residential projects initiated in Vienna and Stavanger has continued in the winning proposals for Collective Housing of Historiador Vicente Ramos and Barrio de San Antón in Alicante, but also in the field of Houses like the IF House. All this drift through the different scales of the urban project ends up finding its recent examples in proposals for a Master Plan like the Rehousing Project for 1060 families in Elche or the awarded entry in Europan 13 that undertakes the Urban Revitalization of the technological area of Forus (Norway) which evidences the peak of maturity in this professional drift towards a more critical understanding on urban development, sustainability and innovation, and that in turn articulate the research project More Than Green. In parallel, these years of delocalized experience in such different geografies, climates and cultures (Austria, Norway, UK, Mexico, Belarus, Korea ...) has provided some specialization in establishing professional collaborations with offices and administrations from all around the worldand understand, moreover, design as a crucial tool for the negotiation of interests and management of controversies without forgetting its necessary ethical and political dimension. But all this has also led PLAY to understand the importance of issues such as identity or recognition of the self to operate in contexts which are increasingly less generic and more specific. So now not only PLAY offers collaborative services in architectural competitions but also consulting on sustainable design and urban development for companies, institutions and administrations of any geographical and / or cultural region. In short, PLAY places the Urbanistic Project as its main work field -regardless its scale- which understands the city as a relational ecosystem and its sustainable development from cultural specificity.
