## Architectural Design Report: Retreat Hub

### Overview

Located in an expansive rural setting, the Retreat Hub is a residential and community space designed for digital nomads seeking flexible living arrangements. The project focuses on integrating sustainable practices with a modular design that fosters a connection to the surrounding environment. Its architectural intent is to create a functional yet aesthetically cohesive space that accommodates the evolving needs of contemporary inhabitants.

### Spatial Strategy and User Experience

The Retreat Hub employs a modular, prefabricated design characterized by a symmetrical structure that allows for scalability. The layout features cross-shaped walkways that facilitate accessibility and enhance natural light throughout the interior. Interior spaces are designed with functionality in mind, incorporating diverse living areas that support various activities, from work to leisure. A notable feature is the 35-foot tall ceiling, which contributes to an expansive visual experience while large window assemblies ensure unobstructed views of the landscape.

### Materiality and Sustainability

The choice of materials reflects a commitment to sustainability and durability. Structural wooden frames provide an inviting ambiance, while lightweight concrete panels enhance thermal insulation and external durability. Roof assemblies utilize waterproof fabrics to safeguard against weather elements, and aluminum window frames ensure structural integrity. Sustainable design strategies include the installation of solar panels for energy needs and efficient rainwater harvesting systems that support water sustainability. The community layout promotes social interaction while preserving individual privacy, reinforcing a cohesive living environment.

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.
