Photovoltaic Roof Catchers and Kingspan Insulation Transforming Urban Rooftops Into Sustainable Living Spaces

Project in-detail

Utilizing Kingspan insulation and photovoltaic roof catchers, this urban initiative transforms underutilized rooftops into functional, sustainable living spaces for city residents.
5 key facts about this project
01
Utilizes Kingspan insulated panels for superior thermal efficiency.
02
Features a modular design for quick assembly and adaptability.
03
Integrates photovoltaic roof catchers for sustainable energy generation.
04
Employs 2000-litre slimline tanks for efficient rainwater harvesting.
05
Incorporates communal green spaces to foster urban biodiversity.
The Nest is an architectural project that focuses on utilizing underused rooftop spaces to create compact, functional living environments suited for urban environments. This design addresses the pressing issues of housing scarcity in metropolitan areas while promoting sustainable practices. The project envisions turning rooftops into green living spaces that foster community interaction and enhance urban biodiversity.

The architecture of The Nest is defined by its modular housing typologies that can adapt to diverse site conditions. Each unit is designed with an emphasis on efficient use of space, maximizing natural light and ventilation through large windows. The spatial layout supports both private and communal areas, allowing inhabitants to engage socially while still enjoying personal space.

The project incorporates various innovative features that differentiate it from typical urban housing developments. Primarily, the integration of environmental sustainability into the design is profound. Each unit is fitted with Kingspan insulated panels for optimal thermal performance, significantly reducing energy consumption. Additionally, the use of photovoltaic roof catchers promotes renewable energy generation, allowing the units to harness solar power.

Water management is another critical aspect of the design. The project includes 2000-litre slimline tanks for rainwater harvesting, contributing to a self-sufficient water supply and reducing reliance on municipal systems. The lightweight, removable steel structures further enhance flexibility, enabling quick assembly and adaptation to diverse rooftop configurations.

The Nest's emphasis on community spaces is notable. By creating gardens and shared amenities on rooftops, the design promotes social interaction among residents, contrasting with the isolation often found in traditional urban living settings. This approach not only encourages a sense of belonging but also contributes positively to the urban ecosystem.

For those interested in an in-depth examination of The Nest, it is beneficial to review the architectural plans, sections, and overall design strategies. Exploring these elements will provide a comprehensive understanding of how this project combines innovative housing solutions with sustainable practices, ultimately contributing to the evolution of urban architecture.

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.
