### 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 Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
