### Project Overview

Cappadocia Retreats is an architectural initiative situated in Central Anatolia, Turkey, focusing on the sustainable reconstruction of dwellings in desert environments. The design integrates traditional architectural principles with modern technologies to address environmental and social needs in arid areas. Emphasizing energy efficiency and environmental adaptability, the project seeks visual harmony with the unique geological landscape of Cappadocia.

### Sustainable Material Practices

The project employs innovative methods for sourcing materials, utilizing excavated earth waste from existing construction sites for the 3D printing of building components. This approach minimizes environmental impact and promotes the use of sustainable materials. Key structural elements include concrete for durability, aluminum framing for thermal insulation, and specialized insulation materials such as rice husks. Additionally, the design incorporates glass sections to maximize daylight while maintaining indoor climate control.

### Spatial and Community Design

Architecturally, the structure features conical forms that resonate with the region's natural rock formations, facilitating airflow and creating varied light patterns throughout the day. Interior layouts promote communal living with open-plan kitchens and living spaces that encourage social interaction, while also providing private areas for residents. Communal gathering spaces are strategically integrated to foster social connectivity, enhancing the sense of community within the retreat.

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.
