The design proposal focuses on converting roundabouts in London into affordable housing units. This approach aims to address the city's ongoing housing challenges while improving public accessibility and promoting a sense of community. The project makes use of often-overlooked urban spaces to create a living environment that fits comfortably within its surroundings while offering new opportunities for residents.

Design Concept
The concept revolves around utilizing roundabouts as development sites. These areas, typically seen as transitional spaces, can be reimagined as places where people live and interact. The design strives to create adaptable structures that make the most of the available space while maintaining sightlines and access to light. This thoughtful integration allows for a blend of architecture and urban life.

Sand Dollar Housing
One option, Sand Dollar Housing, focuses on creating a circulation strategy that goes underground. By placing corridors below ground, the design limits disruption of natural light and valuable views. Above ground, there are open communal spaces with perforated sections that allow for airflow and light to filter into the interiors. Bridges and stair access points encourage movement among the units, while green roofs enhance sustainability and improve the aesthetic.

The Lion of Housing
Another approach is the Lion of Housing, which proposes using roundabout islands as gathering places in the urban environment. The elevated structure stands out, increasing visibility from the streets and inviting pedestrians to engage with the space. A media wall serves a practical function, providing an area for advertisements while also generating revenue to support the project’s ongoing needs.

Modular Approach
Both designs employ modular construction methods. This strategy emphasizes efficiency and cost-effectiveness. Prefabricated elements streamline the building process, making it quicker and more affordable to respond to housing demands. This approach also allows for potential flexibility, enabling the designs to adapt as urban needs change.

Green roofs are a key feature of the project, contributing to energy efficiency and promoting a healthier environment. This connection to nature enhances the resident's quality of life and supports broader sustainability goals within the city. The emphasis on practical design coupled with beneficial environmental features reflects the project’s commitment to creating livable urban spaces.
