Cross-Laminated Timber Microhomes Revitalizing Urban Highways with Sustainable Design

Project in-detail

Utilizing cross-laminated timber and hemp-lime plaster, this development transforms underused highway space into a cohesive community of microhomes designed for sustainable living.
5 key facts about this project
01
Utilizes cross-laminated timber panels to enhance structural efficiency and sustainability.
02
Incorporates hemp-lime plaster for thermal insulation and reduced environmental impact.
03
Features charred wooden shingles for durability and fire resistance.
04
Designed with a bent A-frame structure to optimize space and natural light.
05
Integrates rainwater collection systems for self-sustainability in urban settings.
The architectural project “Reclaim a Highway” addresses pressing issues of urban housing shortages by proposing microhomes on an existing highway infrastructure. This design uniquely transforms unused highway space into a vibrant community that combines residential living, communal facilities, and recreational areas. The project’s primary function is to provide affordable housing while fostering community engagement and enhancing urban dynamics.

The microhome concept within this project employs innovative materials and structures, allowing for efficient use of space and resources. Each unit is designed with a focus on sustainability, featuring materials such as cross-laminated timber, hemp-lime plaster, and recyclable glass. These choices are not only environmentally conscious but also promote local economies through the use of regional materials and techniques.

Innovative Spatial Organization and Community Focus

The architectural design promotes a blend of private and communal spaces. The layout comprises three distinct architectural plans: Engaged, Day-to-Day, and Leisure Layouts. Each configuration emphasizes functionality and adaptability. The Engaged Layout caters to a mixed-use environment where live-work spaces enable residents to maintain a flexible lifestyle. Conversely, the Day-to-Day Layout is optimized for everyday living, featuring multifunctional spaces that maximize efficiency. The Leisure Layout promotes social interaction through open living areas conducive to gatherings, reinforcing a sense of community among residents.

The integration of shared amenities further augments this community-driven approach. Communal areas serve as focal points for social activities, while private balconies extend personal space into the outdoor environment. This design philosophy nurtures connections among residents, encouraging a collaborative atmosphere.

Sustainable Design Practices

Sustainability is a core tenet of the “Reclaim a Highway” project. The architectural design incorporates energy-efficient solutions, including solar panels and a rainwater collection system, fostering independence from traditional utility services. These elements significantly reduce the environmental footprint of the project and emphasize the importance of renewable energy sources.

The choice of materials also enhances overall sustainability. Cross-laminated timber offers structural strength while reducing greenhouse gas emissions compared to conventional building materials. Similarly, the use of hemp-lime plaster not only serves a practical purpose in thermal insulation but also aligns with local agricultural practices.

In summary, the “Reclaim a Highway” project presents an efficient and sustainable architectural solution to urban housing challenges. Its innovative integration of microhomes within the urban fabric, combined with a strong focus on community and environmentally conscious design, makes it a relevant model for future developments. Readers interested in the technical aspects of this project are encouraged to explore the architectural plans, sections, and detailed designs to gain deeper insights into its practical applications and design methodologies.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
