Rainwater Harvesting Microhousing with Ocean Views

Project in-detail

Incorporating rainwater harvesting systems and preserving ocean views, this microhousing development transforms leftover urban land into sustainable living spaces for a diverse community.
5 key facts about this project
01
Utilizes leftover urban gore lots for microhousing Features flexible layouts with fold-down beds Incorporates rainwater harvesting systems Preserves ocean views for neighboring homes Includes photovoltaic systems for energy efficiency.

The design focuses on changing "gore lots," the leftover pieces of land within the urban grid of San Francisco, into microhousing options. Located in a busy metropolitan area, it aims to respond to the pressing need for new housing solutions. The central idea is to utilize these spaces, often seen as unbuildable, to create living areas that blend with the surroundings while promoting sustainable living practices.

Concept and Design Approach

Open and airy spaces characterize the design. This method makes the most of limited square footage. Five different housing units are planned, each ranging from 732 square feet to 2,177 square feet. The variety in unit sizes helps meet the needs of a diverse population. Smaller living spaces ensure affordability while still allowing for quality design, setting it apart from many traditional low-income housing models.

Community Sensitivity

Acknowledging potential pushback from residents regarding new developments, the design approach includes input from the community. Care is taken to consider the views of existing homes. Protecting ocean views plays a significant role in the design, helping to maintain positive relationships within the neighborhood. This focus on community integration ensures that the new housing fits well within the established context.

Innovative Features

The layout highlights well-planned elevations and floor designs that prioritize both function and natural light. Features like fold-down beds allow for flexible living arrangements. Additionally, the inclusion of systems for harvesting rainwater and using solar energy reflects a commitment to sustainability. These practical elements support a modern approach to urban living.

Each unit is planned with great attention to detail, maximizing space to improve livability. The thoughtful integration of innovative features makes the design a relevant example of how to tackle housing shortages in dense urban areas while focusing on community needs. The result is a practical solution to a complex issue, demonstrating a clear understanding of both environmental responsibility and social considerations.

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.
