Circular housing integrates dynamic glass facades and post-tension concrete structures to create energy-efficient living spaces that foster community interaction.
5 key facts about this project
01
Circular layout optimizes space and enhances community interaction.
02
Dynamic glass facades provide energy efficiency and aesthetic transparency.
03
Post-tension concrete supports structural integrity while minimizing bulk.
04
Central communal courtyard fosters social connectivity among residents.
05
Variety of unit types accommodates diverse family sizes and income levels.

### Overview

The design presents a residential development focused on addressing housing density and affordability in urban environments. Situated in a metropolitan area characterized by high demand for living spaces, the structure employs a circular configuration that aims to optimize land use while fostering community interaction. The intent is to create a functional living environment that marries contemporary aesthetics with practical solutions tailored for urban contexts.

### Building Configuration and Spatial Strategy

The project features a circular, tower-like structure designed to facilitate communal living. Each unit opens to shared communal areas that encourage resident interaction, enhancing connectivity within the development. The layout maximizes natural light accessibility while ensuring privacy among residents, with a total of 216 units distributed across six floors. The circular organization creates a central open court, which serves as a community space and facilitates the flow of movement throughout the building.

The design includes multiple unit types that cater to diverse living needs, featuring adaptable floor plans. For instance, the lower-level units prioritize accessibility with ample glass surfaces, while mezzanine units incorporate flexible layouts designed for bright, inviting living conditions. Safety protocols, including clearly marked evacuation routes, align with modern regulatory standards, underscoring a commitment to resident welfare.

### Materiality and Sustainability

The construction approach emphasizes the use of innovative materials that enhance both energy efficiency and aesthetic appeal. Insulated Glass Units (IGUs) are utilized to improve insulation while allowing for visual continuity between the interior and exterior spaces. Curtain wall systems contribute to passive solar gain, facilitating natural ventilation within the living environment. Post-tension concrete slabs enhance structural strength while minimizing the footprint of structural elements, thereby maximizing usable space.

Moreover, the integration of dynamic glass allows residents to adjust light exposure according to their comfort, promoting energy efficiency. The entire design reflects an alignment with sustainable practices, focusing on reducing energy consumption and enhancing the ecological balance in urban settings. The project’s unique circular geometry not only provides structural stability but also actively encourages social interaction, setting it apart from conventional high-rise developments.

`
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.
