## Project Overview

The project aims to convert underutilized rooftop spaces in urban environments into functional, eco-friendly living areas. Focusing on addressing contemporary housing challenges, it offers sustainable solutions in densely populated metropolitan areas. By enhancing existing structures rather than developing new ones, the design seeks to promote a balanced coexistence of personal space and community interaction while prioritizing environmental consciousness.

## Spatial Configuration

The design introduces adaptable housing typologies that cater to specific site conditions and resident needs. These units—ranging from private sleeping spaces to communal gardens—strike a balance between individuality and collaboration. Spatial divisions are planned to foster social interaction without compromising personal privacy, with interiors designed for multifunctionality. The project also features dynamic facades that integrate with the urban landscape, utilizing expansive windows to enhance natural light and ventilation while creating visual connectivity with the city.

## Material Selection and Sustainability

The project employs advanced materials that prioritize durability, energy efficiency, and comfort. Key components include Kingspan Insulated Panels for superior insulation, photovoltaic systems for renewable energy generation, and slimline tanks for efficient rainwater management. The structural elements are lightweight and designed for easy transport and assembly, offering flexibility in adapting to various rooftop configurations. Through the incorporation of these features, the project significantly minimizes carbon footprints and promotes sustainable living practices, reinforcing its commitment to community integration and environmental resilience.

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.
