Crumpled metal foil beneath solar panels enhances thermal efficiency in modular units positioned above urban parking, creating sustainable and affordable housing in a densely populated setting.
5 key facts about this project
01
Crumpled metal foil reflects infrared radiation beneath solar panels.
02
Modular units are constructed above existing parking structures.
03
Configured layouts include one and two-bedroom apartments.
04
Large windows enhance natural light and views while reducing energy use.
05
Design emphasizes sustainability with an efficient energy capture system.

The design addresses critical housing needs in San Francisco, a city known for high living costs and limited affordable options. By placing modular housing units above existing parking lots and flat rooftops, the design aims to increase urban density and make better use of available space. The overall concept blends sustainability with practicality, providing a viable solution for those seeking affordable living in a challenging market.

Materiality and Sustainability

Sustainability is a key focus, exemplified by the solar panels installed on the modular units. These panels face south at a 23-degree angle, maximizing their ability to capture energy from the sun. This setup ensures that the living spaces can generate their own energy, supporting both the residents' needs and local energy regulations.

Crumpled metal foil serves an important role in the design. Positioned beneath the solar panels, it reflects infrared radiation, which helps to keep the units cooler. Metal layer glazing is applied to other sides of the buildings to effectively address indirect sunlight, enhancing thermal performance and creating a comfortable indoor environment.

Functional Layout and Design Elements

The modular units feature layouts that cater to various living needs, with options for one-bedroom and two-bedroom apartments. Each apartment comprises two modules, designed to make the most of available space. The setup includes kitchens, living and dining areas, and bathrooms, striking a balance between private and shared spaces.

Natural light is a fundamental design consideration, highlighted by the use of large windows throughout the units. These generous openings offer beautiful views and allow ample sunlight to pour into the living spaces, reducing the need for artificial lighting during the day. This focus on natural light helps create warm and inviting interiors.

The design exemplifies modern sensibilities while addressing practical housing challenges. By repurposing underused urban areas into functional residential spaces, it presents a thoughtful response to the ongoing housing issues in the city. The approach combines sustainability and livability, ensuring that residents have access to energy-efficient homes in a crowded urban setting.

`
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.
