The TreeHotel is an experimental project of architecture and design made by Studio Dass that addresses essential topics for the future of our society: the evolution of urban life into a natural ecological environment. The TreeHotel was built in the Jardim da Estrela in Lisbon, Portugal and served as an "hotel" during the Experimenta Design09. In the meanwhile as been touring through Portugal and stayed in Silves, near the river Arade, Leiria, near the river Lis, and was lately in the Botanical Garden of Coimbra.Why a tree house?A tree house is a magical place, a romantic hideaway in the nature. Micro spaces that are placed between the trees to play, work, relax or dream! Here we come with memories, new thoughts and through our imagination we achive to be observers of the world we live in, and be critical that allows us to reach new levels of discovery and understanding.The inspiration of this Micro hotel is not architecture, but nature itself. It´s small scale allows us to have an experimental vision of the creative process, to create and investigate new forms and features that are associated with this type of scale. It is an opportunity for developing new materials and methods of pre-production, saving natural resources. For this project Studio Dass joined up with biologists, landscape, construction companies, industries, and were outlined concrete objectives for this project:Foment Sustainability The project demonstrates a sustainable concern, not only just in its physical implementation, but in the ideas and thoughts which may stimulate and increase the attention of people to important values that can inspire our society in future. Explore new paths in Architecture and Design Encourage the search for new paths in the creative process and project. Finding new strategies programs (flexibility and range of functions), create architectural quality in view of its aesthetic impact (space, form, light) and context (relationship with the surrounding natural or built). Investigate new materials and technologies Development of concept taking into account the integration of new materials, or sustainable materials, either in structure, services, or on the subject, at all scales of project. Investigation of construction technology, operations and maintenance procedures that are simple, cheap and multiple applications. Promote education and awareness Creating an original project, realistic, with great impact in the city of Lisbon and its inhabitants in order to promote the dissemination of knowledge, and consequent change of habits in terms of architecture and design, sustainable construction, reducing waste, promote biodiversity and protection of nature. Encouraging Industry The TreeHotel is a project to be developed directly with industry. The creation of synergies to encourage industry to work together for your benefit, to promote research into new solutions and optimize production processes. The project won the first prize in the Larus architecture award 2010; was finalist in the wood architecture award Prémio Floresta 2011; was nominated for the architectural prize Outros Mercadus 2010; selected for the green project awards 2010 and for the Tourism Prize 2010 in the sustainability cathegory.
