## Project Overview

Located in Bonn, Germany, the Rampart project is designed to blend the urban environment with the natural landscape, focusing on sustainability and community interaction with the waterfront. The intent is to create a vibrant space that serves multiple functions—commercial, residential, and recreational—thereby revitalizing the area and promoting connectivity among its users.

### Spatial Strategy and User Engagement

The project's layout emphasizes multi-functional spaces that accommodate a diverse range of activities. By integrating residential, commercial, and leisure areas, it aims to foster economic vitality while encouraging community engagement. Public decks and walkable promenades are strategically placed to enhance access to the waterway, promoting social interaction and outdoor activities. This design approach aims to cultivate a lively atmosphere conducive to community gatherings and public enjoyment.

### Material Use and Environmental Considerations

The selection of materials reflects a commitment to sustainability and aesthetic unity. Concrete is used for its structural integrity, while wood contributes warmth and a connection to nature. Extensive glazing maximizes natural light and visual openness, establishing a fluid relationship between indoor and outdoor environments. Sustainable practices are embedded in the design, featuring living walls, green roofs, rainwater harvesting, and solar panels, all aimed at enhancing ecological balance and minimizing environmental impact. The design is historically contextual, aligning with Bonn’s architectural character while pursuing contemporary relevance.

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.
