Subscribers only
A mycelium-insulated microhome embedded within a bridge structure exemplifies urban sustainability by harmonizing living space with existing infrastructure, creating a compact solution for modern urban housing.
5 key facts about this project
01
Mycelium serves as the primary insulation material, emphasizing sustainability and biodegradability.
02
The microhome is structurally integrated into an existing bridge, maximizing urban space efficiency.
03
Wind turbines are incorporated into the design to generate renewable energy for the microhome.
04
Rainwater harvesting systems are integrated, promoting water sustainability within the urban setting.
05
Public spaces surrounding the structure encourage community interaction and engagement.

## Overview

Located along the Eskisehir Highway in Ankara, Turkey, the project embodies principles of sustainable urban design in a contemporary urban context. The primary intent is to foster a relationship between the built environment and natural surroundings, addressing current urban challenges while promoting environmental responsibility and integrated living.

## Spatial Strategy and Community Engagement

The design features a unique integration of living spaces within a bridge structure, effectively repurposing existing urban infrastructure. This arrangement reduces land consumption and increases urban density. The interior layout includes designated zones for cooking, sleeping, and social interaction, optimizing functionality within a compact footprint. The incorporation of large windows enhances natural light, contributing to the overall well-being of residents and providing a healthier living environment. Public spaces are strategically integrated to facilitate community interaction, inviting both residents and passersby to engage with the environment and one another.

## Materiality and Sustainability

The project employs a variety of sustainable materials, including mycelium, steel, natural wood, and concrete. Mycelium, utilized for insulation and as an envelope material, is lightweight and biodegradable, aligning with eco-friendly building practices. Steel serves as the primary structural component, chosen for its durability and recyclability, while natural wood adds aesthetic value and carbon sequestration benefits. The design incorporates various sustainable systems, including wind turbines for clean energy generation and mechanisms for rainwater harvesting and greywater treatment. Additionally, a self-contained composting toilet minimizes water usage, reinforcing the project's commitment to efficiency and environmental stewardship.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
