### Project Overview

The Bookhouse project comprises two interrelated components: the Bookhouse Microhome and the Bookhouse Book Club, located near Lake Michigan, on the outskirts of Chicago. This initiative promotes sustainability, community engagement, and personal reflection, establishing a comprehensive approach to architecture that intertwines individual solace with communal interaction. Each structure is designed to facilitate various forms of engagement—from solitary contemplation to collaborative learning.

### Spatial Strategy and Functionality

The Bookhouse Microhome is engineered as a minimalist retreat, prioritizing a functional, yet comfortable interior that enhances the user experience. Its layout includes a sleeping area illuminated by natural light, a compact dining space, a designated work area, and a living room that encourages relaxation and connection with the surrounding environment. This design fosters a balance between personal space and interaction with nature, while the use of vertical wooden slats in the façade integrates the building with its landscape.

In contrast, the Bookhouse Book Club serves as a communal hub focused on educational and cultural exchange. It features strategically placed windows that facilitate natural light throughout, creating an inviting atmosphere conducive to discussion and collaboration. The library area of the Club doubles as a venue for social events and educational programs, catering to a diverse audience and reinforcing the project's commitment to community integration.

### Material Selection and Sustainability

Sustainability is a central tenet of both structures, evidenced by the selection of materials and the incorporation of renewable energy systems. The Microhome utilizes KINGS PAN insulated panels for energy efficiency, while the Book Club continues this focus on eco-friendly materials throughout. Each building incorporates renewable energy technologies, including wind turbines and solar panels, which not only ensure energy autonomy but also serve as practical demonstrations of sustainability. Rainwater harvesting systems are integrated into the Microhome to minimize reliance on municipal water sources, further enhancing the project’s ecological responsibility.

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.
