### Project Overview

The redesign of panel housing in Kharkiv, Ukraine, focuses on improving residential structures in a post-conflict urban context. The intent of the project is to create cohesive living environments that support community well-being while addressing the challenges posed by economic and social instability. The design draws inspiration from the sunflower, a national symbol of Ukraine, which embodies resilience and hope for the future.

### Spatial Strategy and Community Integration

The project emphasizes the integration of public spaces to enhance community interaction and connectivity. By incorporating community gardens, play areas, and facilities for rainwater harvesting, the design promotes sustainable practices while facilitating social engagement among residents. The residential units are configured with modular designs, allowing flexibility to accommodate varying family structures and social dynamics. Vertical circulation and communal areas are strategically designed to encourage interaction, thus fostering a sense of community.

### Material Selection and Environmental Considerations

The materials selected for construction play a crucial role in the project's sustainability and durability. Ultra-High-Performance Fiber-Reinforced Concrete (UHPC) is employed for its strength and environmental benefits, while metal components help streamline structural connections. Wooden elements are utilized within the interiors to provide warmth and aesthetic appeal, and glass facades enhance natural lighting and visibility. These choices reflect a commitment to creating a resilient living environment that balances functionality with ecological mindfulness.

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.
