Bottle house of Maria Ponce

Plastic bottle house

This house was built from empty plastic bottles by Maria Ponce, 76, who lives in the village of El Borbollon, El Salvador. Maria built this house in 2003 with plastic bottles because she did not have enough money to make it in the usual way. Below, Maria stands inside of her home, showing off the roof, which is also built from plastic bottles.

Eighty-six-year-old Maria Ponce, stands at the door of her house in the village of El Borbollon, El Transito, west of San Salvador, on March 14, 2017.


The project of PETree was started by PET-MAT (Nováková – Prokop) and Experimental studio Achten-Nováková at Fa CTU Prague with support of KMV a.s. It is a pilot project of an experimental construction made by selfbearing PET-bottle structure in form of a 5 meters tall christmas tree. The structure is hollow and works as an exhibition room in order to mediate information on the facts about reusable waste, focused on plastic garbage, represented by PET bottles. The tree has the aim to show the value of plastic PET garbage and its unbelievable quantity, which depends on consumers: all of us. The tree consists of 12 thousand 1,5l PET bottles, connected by wireframe and ropes. One Primary school and twelve highschools from Prague, Mladá Boleslav, Kolín, Slaný and Sedlčany took part on collection and they were also building a construction panel with decoration. The tree is enlightened at night with interesting lightshow delivered by IIM CVUT Prague. The PETree exhibition is open daily from 9 AM to 10 PM.
