Constructed from reclaimed plastic detritus, this microhome utilizes a pneumatised cladding system to challenge traditional ownership concepts while serving as a community space for urban residents.
5 key facts about this project
01
Constructed using waste materials, primarily high-density polyethylene and polystyrene.
02
Utilizes a pneumatised cladding system for increased insulation and reduced weight.
03
Functions as a temporary hub for community waste collection and resource sharing.
04
Features shelves that promote personal display while ensuring privacy.
05
Incorporates internal fittings sourced from architectural salvage to enhance sustainability.

The project explores a microhome concept within the lively context of Southampton’s docklands. By redesigning an empty shop, the work aims to blend sustainability and community involvement. The design challenges typical housing concepts by using existing buildings and resources, encouraging a conversation about managing waste and local identity through its thoughtful design.

Sustainability and Resource Use

The first step in the project involves acquiring a 1-2 storey empty shop with a flat roof, creating a foundation for diverse uses. The shop acts as a temporary gathering point for collecting waste materials, specifically high-density polyethylene (HDPE) and polystyrene sourced from local residents and nearby businesses. This approach showcases a practical solution to environmental issues by turning discarded materials into usable design elements.

Design Philosophy

The concept is framed around the idea known as "What a Lot of Things." This perspective invites residents to rethink ownership, as the design aims to create a microhome that allows for minimal possessions. Innovative details, such as the pneumatised cladding made from injected air, contribute to a lightweight yet sturdy structure. This design not only maintains strength but also provides insulation, addressing the requirements of modern living.

Adaptability and Community Connection

The conversion of the shop into a microhome emphasizes the flexibility of urban spaces. Features such as shelves hidden behind small panes ensure privacy while also allowing for personal displays. This setup encourages residents to reflect on what they choose to show, creating a bond with their belongings and promoting their individual expressions within shared areas.

Material Reuse and Functionality

The project goes further, incorporating internal fittings, grillage shelving, and floorboards salvaged from previous buildings. This choice strengthens the commitment to sustainable building practices while showing how reclaimed materials can play an essential role in urban design. Each element in the microhome contributes to a story of practicality, establishing a direct connection between how spaces are designed and how they function.

The cladding, painted to resemble traditional wooden shingles, also plays a role in environmental responsibility by helping to prevent leaching of microplastics. This attention to detail reflects broader ecological concerns while providing a consistent appearance for the overall structure.

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.
