## Project Overview

"The Overhead Department" is an architectural design conceived for the urban landscape of Hong Kong, aimed at addressing the pressing housing crisis through sustainable and affordable solutions. The project leverages a modular design approach that maximizes vertical space, aligning with the diverse needs of the city's varied demographics. By embedding housing solutions within the urban fabric, it seeks to integrate living spaces into the densely populated environment.

### Spatial Strategy and Public Interaction

The design employs a **pixelated modular housing system** tailored to the spatial constraints of Hong Kong. This strategy allows for a range of living options, including shared units for couples, singles, and families, thus accommodating various household configurations. The vertical arrangement of units permits natural light and air to permeate the building and enhances ground-level public spaces. Outdoor terraces and communal green areas are integral to the design, fostering social interaction and community engagement among residents.

### Material and Environmental Performance

The project prioritizes durability and sustainability in its choice of materials. Anticipated materials include reinforced concrete for structural integrity, steel framing for flexibility, and glass facades to enhance natural lighting while offering a contemporary aesthetic. Additionally, eco-friendly finishes are intended to promote environmental conservation within interior spaces. The incorporation of vertical gardens and balconies supports biodiversity, creating a serene atmosphere that contrasts with the surrounding urban environment.

The careful design and strategic material selection serve to enhance urban density while promoting a sense of community and addressing the housing needs of a growing population. The focus on connectivity and transparency further emphasizes the project's commitment to an open living environment conducive to collaboration and resident interaction.

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.
