Constructed from recycled HDPE, this modular housing solution integrates rainwater harvesting and flexible spaces, addressing urban living needs with a focus on sustainability and efficiency.
5 key facts about this project
01
Constructed entirely from recycled HDPE, reducing reliance on new materials.
02
Integration of rainwater harvesting systems enhances sustainability and resource management.
03
Modular design allows for quick assembly and adaptability to various urban contexts.
04
Features flexible living spaces that accommodate changing resident needs.
05
Employs post-tensioning techniques for structural stability and efficiency.

The ReFabMod project presents a modern approach to modular housing, situated in an urban environment where sustainable practices are becoming essential. The design focuses on creating adaptable living spaces that prioritize efficiency and environmental responsibility. Here, the aim is to combine functionality with advanced technology for a better living experience, responding to the changing needs of residents.

SUSTAINABILITY INITIATIVES

The project places significant emphasis on sustainability by recycling High-Density Polyethylene (HDPE) plastic. In the United States, over 115 million pounds of this type of plastic are discarded daily, which presents both a challenge and an opportunity. By transforming HDPE marked #2 into building materials, the project not only reduces waste but also contributes to resource conservation in construction. This recycling process begins with the collection of plastic waste, which is then processed into usable components, minimizing the environmental impact.

FUNCTIONAL LAYOUT

ReFabMod incorporates a carefully planned layout that includes various essential areas for living. There are designated spaces for storage, communal living, a flexible area, a kitchen, baths, showers, and outdoor features like patios and gardens. This arrangement enhances both comfort and community among residents, giving them multiple options for how to use the space. Each area is designed to encourage connection while addressing individual needs, showcasing how thoughtful design can facilitate daily life.

MODULAR CONSTRUCTION TECHNIQUES

The construction methods used in the project are innovative and efficient. Using large format 3D printing and extrusion technology, building parts are created from recycled plastic pellets. Once these parts are manufactured, they can be prefabricated into larger sections or simplified into individual components, which makes transportation and assembly easier. A sectional post-tensioning system is employed to add strength and stability to the entire structure. This approach allows for a faster assembly process with less disruption on site.

The design inherently incorporates elements that support resource management. Rainwater storage and collection systems are integral to the project, enhancing the overall environmental strategy and demonstrating a commitment to sustainable living practices.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
