This project proposes a systematic and sustainable solution towards the refurbishment of post-war concrete buildings.

The method derives from the urban-cliff hypothesis identifying our city as a template cliff habitat. It introduces urban wind simulation as a dynamic tool to carve the exiting building volume and generate the co-living spaces for humans and non-humans. It applies style transfers and digital fabrication to transform the carving spaces and original façade in the sense of the assembly. The utilisation of hemp concrete, which can provide subtracts for the non-human species, as a low-carbon alternative material for concrete, makes the refurbishment more sustainable.

The method also combines the concept of a green corridor to consider the refurbishment on a large urban block scale and chooses Athens as the design site. When people believe in refurbishing a building to be more eco-friendly, it needs to be on a larger scale. Individual greening of a buildings is not having an effect, and simply putting a green façade outside a building makes no difference on an urban scale. This project looks to make our cities greener and refurbish in a more sustainable method by applying it to lots of buildings. Green corridors generated in old building complex serves the community and the city.
