### Project Overview

**Project Title**: Hortus Conclusus
**Location**: Latvia
The Hortus Conclusus project is situated in an area characterized by significant forest cover, with 40% of the landscape dedicated to woodlands. The design aims to integrate architectural elements with the surrounding ecology, fostering a dialogue between the built environment and the natural setting.

### Spatial Configuration and User Interaction

The architectural layout centers on movement and interaction, featuring a series of interconnected spaces that promote both social engagement and personal reflection. Key components include an entrance hall that establishes a welcoming atmosphere, living spaces and bedrooms oriented to connect with the landscape, and a walled garden that affords privacy while encouraging ecological interaction. Dining and kitchen areas designed with functionality in mind incorporate elements that allow inhabitants to engage with the surrounding gardens.

### Material Selection and Sustainability

The structure employs a thoughtful combination of materials, including blue clay bricks for their thermal mass properties, timber framing for both aesthetic warmth and structural support, and strategically placed glazing to maximize natural light and views. Sustainable features include rainwater collection systems, gray water systems for irrigation, and solar technology that enhances energy efficiency. The surrounding landscape serves as an extension of the architectural environment, with vegetable gardens integrated to facilitate personal cultivation and promote health and wellness.

The project includes a well-being spa that features a hot tub adjacent to a lake and treatment rooms arranged around a garden courtyard. This design choice enhances users’ sensory experiences by offering views of the outdoor landscape, further emphasizing the connection between the indoors and the natural environment.

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.
