More then ever we are demolishing our built environment and obliterating our nature in the sake of progress. This attitude towards the existing environment has high costs on many levels. As a coming architect I am inspired to think and see value in what we already have around us, both the built and the living. In the design process words like securing, preserving and maintaining has gained new strength. And only when needed, additions are made. This diploma work explores aspects of preservation of architecture and ecology through a existing example; Kristiania Teglverk at Bryn in Oslo. Attempts to discover and seek correlation between these two fields are tested. Kristiania Teglverk, a former brick factory from 1898 had and have a intertwined relation to the surrounding nature and the Alna River passing by. I have approached and learned about the building and the surrounding ecosystems taking different paths. These paths or branches are organized in five delivery documents. They can be seen as separate documents or all together feeding in to my attempt to get closer to the relationship between Architecture and Ecology, with old Kristiania Teglverk as the centre of attention. A major focus of this delivery has been the search in finding a program and a proposal for the building that can inherit the discussion of the relationship between Architecture and Ecology. This search of program was not linear and can be seen in fragments in the different documents attached, more or less highlighted. The conclusion of the search for program ended in two levels - The Landscape and the Building. The two levels are connected by the existing path D10 following the Alna River from the Fjord almost to the source in Marka. This path enables the visitors to explore and discover the diversity of nature, the collection of old industrial buildings along the river and their mutual relation. The path is broken at the Bryn area with Kristiania Teglverk in the centre.
