Utilizing curvilinear forms, recycled concrete, and modular steel construction, the design creates adaptable urban housing that prioritizes community engagement and sustainability.
5 key facts about this project
01
Curvilinear forms enhance natural light and circulation throughout the living spaces.
02
Recycled concrete elements are incorporated for both structural integrity and aesthetic appeal.
03
Modular design allows for flexible configurations to accommodate diverse family needs.
04
Outdoor loggias foster community interaction while providing sheltered gathering spaces.
05
Insulated panels optimize energy efficiency and thermal performance in urban environments.

**Project Overview**
The Saltivka: Kintsugi initiative presents a modular residential design that draws inspiration from Kintsugi, the Japanese tradition of repairing broken pottery. The project is situated in an urban environment where innovative housing solutions are essential due to socio-economic challenges. Embedded within its design is a philosophy that embraces imperfections, transforming perceived flaws into defining features.

**Modularity and Structural Design**
The architectural framework consists of modular building blocks optimized for flexibility and adaptability. A one-way vaulted slab system allows for effortless repairs and configurations within individual units, promoting sustainability and ease of maintenance. Additional design elements include strategically placed elevator shafts to facilitate circulation and integrated staircases for enhanced accessibility, reinforcing both safety and community interaction. The layout of interconnected units affords residents the opportunity to personalize their living spaces while maintaining a cohesive structural identity.

**Material Selection and Public Integration**
The material palette reflects a commitment to durability and environmental conscientiousness, featuring precast concrete for structural integrity, steel for flexibility, and wood and glass for aesthetic warmth and lightness. Innovative use of salvaged concrete enhances both the aesthetic qualities and the sustainable ethos of the project. Public engagement is fostered through expansive green areas and pedestrian walkways, facilitating communal interaction. Loggias provide covered spaces for social gatherings, while the inclusion of playgrounds and shared community areas further enhances spatial connectivity and cultural integration.

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.
