Showcasing a modular framework of precast concrete panels and integrated solar technology, the development creates efficient housing solutions that encourage community interaction and sustainability.
5 key facts about this project
01
Utilizes an integrated system of modular precast concrete panels for efficient assembly and adaptability.
02
Features extensive green roofs that enhance insulation and promote biodiversity within the urban environment.
03
Incorporates photovoltaic cells in design to achieve energy self-sufficiency for communal areas.
04
Design includes communal balconies that foster social interaction among residents and provide outdoor access.
05
Integrates underground facilities for essential services, minimizing surface footprint and enhancing safety.

### Project Overview

The Join Hands project is situated within a dynamic urban landscape, designed to address contemporary challenges in housing and community engagement through a modular architectural approach. The development integrates self-supporting structures to enhance both functionality and sustainability, creating a living environment that facilitates community interaction and urban integration.

### Spatial Strategy and Modularity

The design prioritizes modularity, enabling rapid assembly and adaptability as community needs evolve. Individual units are structured as modular components, each equipped with personal outdoor spaces, such as balconies, enhancing the living experience while ensuring privacy. The interconnected modules promote efficient circulation and flexibility in interior configurations, allowing spaces to be reconfigured as required.

Shared public areas, along with interconnected green spaces, are deliberately incorporated into the layout to foster social interaction and connection with nature. These green areas not only enhance the aesthetic quality of the environment but also contribute to ecological balance by encouraging outdoor activities within the urban context. Additionally, strategically placed underground facilities provide essential resources and enhance safety for residents.

### Materiality and Sustainability

The architectural framework utilizes a metallic structure that supports open layouts and durability. Precast concrete panels (300 mm thickness) serve as facade materials, providing thermal insulation and resilience. The building design emphasizes energy efficiency, employing materials such as EPS insulation and glass railings to maximize natural light and views in communal areas.

Sustainability initiatives are central to the project’s design, including the recycling of concrete and the integration of photovoltaic cells within the canopies to harness solar energy. Careful selection of materials minimizes waste and reduces the overall carbon footprint, reflecting a commitment to environmental stewardship throughout the project's lifecycle.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
