Crumpled Metal Foil and Solar Panels Elevate Modular Living Above Urban Parking

Project in-detail

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 MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
