5 key facts about this project
01
Elevated green voids function as environmental filters for improved air quality.
02
Modular units enable flexible housing configurations suitable for varying needs.
03
Perimeter building blocks provide structural support while maximizing open space.
04

05
Design draws inspiration from the original layout of Robin Hood Gardens.

The design addresses the significant housing shortages in London by exploring new ways to use urban space. Located in a densely populated area of the city, the idea is to convert underused public areas into functional housing. The overall approach focuses on bringing empty public layers to life, creating spaces that serve the dual purpose of providing homes while enhancing community interactions.

Urban Layout and Green Spaces

The project features an arrangement of four urbanized blocks surrounding a central green void. This void includes parks, plazas, and shared spaces that encourage socializing and leisure activities. By incorporating green areas at the heart of the design, the plan aims to enrich the daily lives of residents and visitors. The open spaces serve as gathering points, fostering a sense of community in a busy urban environment.

Vertical Integration

A key aspect of the design is the vertical extension of these green voids. By effectively duplicating and elevating these areas, the design creates an environmental filter that responds to factors such as rain and sunlight. This approach ensures better ventilation and allows natural light to reach living spaces. The result is a series of microenvironments that prioritize comfort and well-being for residents while redefining the role of public spaces in an urban setting.

Modular Housing Solutions

The structure relies on perimeter building blocks for support, allowing adaptability for future developments. This lightweight framework facilitates the integration of modular housing units, which can serve various purposes, from residential living to recreational areas. With hanging gardens incorporated into the design, there are additional spots for quiet reflection and interaction, contributing to a richer urban experience.

Focus on Robin Hood Gardens

Located at Robin Hood Gardens, originally designed by Alison and Peter Smithson, the project maintains the spirit of the original public space concept. By incorporating contemporary design elements, the new proposal breathes life into the existing site while addressing the need for more housing. The balance between historical context and modern needs is fundamental to ensuring the project is both functional and respectful of its surroundings.

Balconies and terraces enhance the elevated living spaces, offering views of the urban landscape. These features add to the comfort of residents and encourage connections with the outdoors. The thoughtful design details make the living environment more inviting and engaging, aligning with the goal of integrating homes within a vibrant community.

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.
