General Description

The "Life, Nested" architectural project is designed to address the ongoing housing crisis in urban centers, particularly in San Francisco, California. This project proposes an innovative approach to micro housing by utilizing air rights above existing residential structures, effectively creating compact living spaces that cater to individuals with low-income backgrounds. The architectural design emphasizes space efficiency while promoting community interaction and sustainability.

The project's primary function is to provide affordable living options in a dense urban environment. Each unit features essential amenities, including a kitchenette, bathroom, and workspace, arranged thoughtfully to maximize the use of limited space. The design not only prioritizes individual comfort but also facilitates communal activities through shared amenities such as lounges and communal kitchens, thereby fostering a sense of community among residents.

Unique Design Approaches

What distinguishes "Life, Nested" from conventional housing projects is its focus on elevating micro housing structures rather than expanding horizontally. By lifting the units approximately 13.5 meters above existing buildings, the project minimizes disruption to the urban fabric and preserves the aesthetic character of the neighborhood. This elevation also allows for expansive views and increased natural light, contributing to the overall quality of living spaces.

The architectural design employs a range of sustainable materials, including recycled steel and low-VOC finishes. These choices reflect a commitment to reducing the environmental impact of the project while ensuring durability. The inclusion of solar panels and water harvesting systems further enhances the self-sufficiency of each unit, addressing energy efficiency and resource conservation.

Additionally, the layout of "Life, Nested" incorporates adaptive reuse of urban infrastructure, demonstrating an innovative use of space in a crowded city. This modular approach offers flexibility for future developments and demonstrates a possible framework for addressing similar housing challenges in various urban contexts.

Community Integration and Sustainability

The design of "Life, Nested" integrates communal spaces that encourage interaction among residents, an essential aspect of urban living. By providing shared areas for socialization and collaboration, the project nurtures a sense of belonging and togetherness.

In terms of architectural systems, the project incorporates advanced HVAC solutions that optimize energy consumption while ensuring resident comfort. Waste management systems, including greywater recycling and composting options, contribute to the sustainable operation of the building, reinforcing the project's environmentally-sensitive approach.

Overall, "Life, Nested" serves as a progressive response to the pressing issue of housing in urban environments. Its innovative design and sustainable practices offer valuable insights into the future of affordable living spaces. Readers interested in exploring the project further are encouraged to review the architectural plans, sections, and detailed designs for a comprehensive understanding of the architectural ideas and solutions presented in this project.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
