## Project Overview

The project aims to convert underutilized rooftop spaces in urban environments into functional, eco-friendly living areas. Focusing on addressing contemporary housing challenges, it offers sustainable solutions in densely populated metropolitan areas. By enhancing existing structures rather than developing new ones, the design seeks to promote a balanced coexistence of personal space and community interaction while prioritizing environmental consciousness.

## Spatial Configuration

The design introduces adaptable housing typologies that cater to specific site conditions and resident needs. These units—ranging from private sleeping spaces to communal gardens—strike a balance between individuality and collaboration. Spatial divisions are planned to foster social interaction without compromising personal privacy, with interiors designed for multifunctionality. The project also features dynamic facades that integrate with the urban landscape, utilizing expansive windows to enhance natural light and ventilation while creating visual connectivity with the city.

## Material Selection and Sustainability

The project employs advanced materials that prioritize durability, energy efficiency, and comfort. Key components include Kingspan Insulated Panels for superior insulation, photovoltaic systems for renewable energy generation, and slimline tanks for efficient rainwater management. The structural elements are lightweight and designed for easy transport and assembly, offering flexibility in adapting to various rooftop configurations. Through the incorporation of these features, the project significantly minimizes carbon footprints and promotes sustainable living practices, reinforcing its commitment to community integration and environmental resilience.

`
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.
