‘the bottle project’ uses plastic waste to create training hub
‘the bottle project’ is an experimental intervention led by open door design studio & workshop in the city of karachi, pakistan. the architects were approached by a local NGO that works for the welfare of differently-abled people, in the hopes of creating a semi-open handicraft training facility on their rooftop. as such, the idea was to build an accessible, light, and low-cost structure using sustainable materials.
karachi is a city built primarily on reclaimed land; hence there are very few local materials to work with. on the other hand, it is a megacity that generates millions of tons of waste daily. with that in mind, the team attempted to use this waste, specifically plastic bottles, to create a screening block wall paired with a light bamboo structure and coconut palm thatch roof.

the architects‘ proposed structure is quite simple: a sloping roof and a free-flowing plan aiding the easy movement of wheelchairs and people. the most distinct feature of this intervention is the screen wall made of bottle blocks to provide privacy and visual anchoring. ‘our experiments with the bottle block allowed for multiple playful iterations in the masonry design. the bottles are strengthened with sawdust infill, a byproduct of the furniture industry. the sawdust adds a beautiful visual texture to the bottles, along with increasing their bearing capacity,‘ shares the team.
the filled bottles are polished with beeswax, then fixed and cast into concrete bases, allowing them to function in a modular way — similar to bricks or concrete blocks. it was also proposed to pair the bottles with terrazzo to create lightweight furniture. ultimately, the architects argue, this design attempts to pause and identify potential resources that can add value to how and what can be built.
