Mycelium Insulated Microhome Integrated Within Bridge Structure for Urban Sustainability

Project in-detail

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 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.
