### Project Overview
Located in the Liwan District of Guangzhou, Guangdong Province, this architectural initiative aims to respond to the growing needs of an aging population within urban settings. The design is focused on enhancing social engagement for elderly residents, addressing issues such as isolation and lack of stimulating environments. By creating both public and private spaces that encourage interaction across generations, the project seeks to foster community connections through a thoughtful integration of various functions and activities.

### Spatial Configuration
The layout of the project incorporates modular public activity spaces, including elderly activity centers, traditional Chinese medicine facilities, and children’s playgrounds. These elements are designed to facilitate intergenerational exchanges and promote active engagement among users. A spiral transit system enhances mobility within the space, linking different levels while serving as a visually appealing architectural feature. Additionally, observation and community towers offer panoramic views and venue options for public events, thus strengthening the bond among residents.

### Material Selection and Sustainability
The project employs a diverse range of materials, including steel and glass for structural components, promoting both durability and light access. Brightly colored exteriors create an engaging visual landscape, contributing to a welcoming atmosphere. Sustainable and eco-friendly materials are incorporated to align with environmental considerations essential in contemporary urban design. These design choices not only enhance the aesthetic value but also prioritize sustainable practices, underscoring the commitment to a socially conscious architectural framework.

`
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.
