TRILOGY 1 – Plastic & Flood
‘The most overcrowded and backward area in the Philippines,’ and in 1950, the ‘Land of Happiness’ became a post-war area, but the government did not give enough support to rebuild the area, making it a "happy place" for the urban poor. The slum was frequently attacked floods, causing huge casualties. TRILOGY 1 uses a landscape installation of used plastic bottles for disaster relief when floods come. Two installations were made from plastic garbage accumulated in the streets, and a production manual was provided to design at a low cost. The strength of the devices, as well as the materials and strength, have been repeatedly tested and calculated to ensure that they can function properly in the event of a disaster.

TRILOGY 2 – Plastic & Play
In Hapyland, the children have very poor health, education and play conditions, and their future growth is not optimistic. It presents a compelling microcosm of the issue of solid waste management and how the children in the community live with trash as a part of their lives. As play is the natural part of children's lives and an important medium to help healthy growth. By giving the six main spaces in the street different attributes of play space, this project will use low-cost materials to create a child-friendly street that can meet the different play requirements of the children in Happyland. In the TRILOGY 2 We consider localization and humanization, and also tries to rethink how to transform the original low quality landscape community into a sustainable and healthy place for the next generation.

TRILOGY 3 – Plastic & Art
In the TRILOGY 3, we rethink how to use local plastic waste to design a co-building system and residents could have a chance to change their community. In the environment of overwhelming rubbish, the playgrounds and streets that could be used have been taken over by rubbish, so that many children and other residents have no place to play or do other community activities. The strategy is to create a plastic art space using recycled materials and a co-building system. It not only could reduce the Plastic wastes to return the playground to local residents but also can provide some special spaces where were attracting artists and tourists from the city, besides these residents could sell their homemade recycled goods to increase their daily income.


Waste management is a common topic of discussion over the world. In our trilogy, we rethink how recycled materials can be used to build an installation space that the community can participate in designing and constructing together in the common spaces, and to rethink different lives in slums like Happyland.

We think the trilogy further provokes thoughts about this material and the design of slum spaces. The design will express how the public should use a more rational approach to solving the problems of waste management in the slums with limited budget, avoid using expensive materials and complex constructions. We believe the trilogy can provide a platform for slum dwellers to express themselves and create a positive community culture that thrives in the slum.
