PIR Insulated Modular Units Integrated Into Historical Railway Arches for Affordable Urban Living

Project in-detail

Utilizing PIR insulation and modular construction techniques, this housing initiative transforms historical railway arches into adaptable living spaces, addressing urban affordability while respecting the architectural heritage of the city.
5 key facts about this project
01
Utilizes PIR insulation panels to enhance thermal efficiency while minimizing noise.
02
Incorporates prefabricated modular units for rapid assembly and flexible configurations.
03
Maintains the historical integrity of Victorian-era arches while integrating modern living spaces.
04
Integrates community gardens and shared green spaces for enhanced social interaction.
05
Features large glass storefronts that promote natural lighting and visibility into common areas.
The VIAdwell project addresses the pressing need for affordable housing in urban settings by repurposing underutilized railway viaducts in the London Metropolitan Area. This project aims to create a sustainable living environment by integrating modular housing units into existing structures, thereby providing innovative solutions in housing design. The architectural approach emphasizes practicality, flexibility, and community engagement, leading to a revitalization of historical infrastructure for contemporary use.

Design Innovation and Modularity

The VIAdwell project is distinct in its modular design approach, allowing for the assembly of residential units that can be adapted to accommodate various household sizes. Each modular unit consists of prefabricated elements, minimizing construction time on-site and reducing waste. The design focuses on the efficient use of space, providing options for configurations ranging from single-occupancy dwellings to family-sized accommodations.

Incorporating metals and insulation panels, the architecture maintains an industrial aesthetic while ensuring sound insulation from the surrounding environment. The utilization of large glass surfaces promotes natural light, enhancing the interior atmosphere while fostering a sense of community through visual connection with the outside environment. The design integrates gardens and communal areas, further encouraging social interaction among residents and promoting a sense of belonging.

Accessibility and Community Integration

The project also prioritizes accessibility, featuring wider doorways and ramps to support individuals with mobility challenges. This emphasis on inclusivity reflects a broader consideration for diverse population needs. Furthermore, the development incorporates green spaces that not only enhance the aesthetic value of the environment but also contribute to urban biodiversity.

The strategic selection of materials, including PIR composite walls for insulation, provides thermal efficiency while respecting the historical context of the viaduct structure. By maintaining the architectural integrity of the Victorian-era infrastructure, the project establishes a dialogue between past and present.

For deeper insights into the architectural plans, sections, and design principles of the VIAdwell project, readers are encouraged to explore the project presentation further. Understanding the unique architectural ideas and design elements will provide a comprehensive perspective on the innovative solutions presented in this housing initiative.

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.
