Reflective Surfaces and Sustainable Materials Enhance Underground Living Spaces

Project in-detail

Utilizing modular reflective surfaces and sustainable materials, the design maximizes natural light in subterranean living spaces, creating a functional and efficient residential environment.
5 key facts about this project
01
Utilizes an innovative modular mirror system to enhance daylight penetration into underground areas.
02
Features a bent A-frame design that optimizes structural integrity while minimizing surface disruption.
03
Incorporates charred wooden shingles for improved durability and weather resistance.
04
Employs cross-laminated timber panels to reduce carbon footprint and enhance sustainability.
05
Integrates biophilic design elements, including indoor planters that promote natural ventilation and well-being.
The Periscope project represents a novel approach to subterranean architecture, designed to optimize living spaces beneath the ground while maintaining connectivity to the natural environment. The structure is characterized by its unique periscope-inspired design, facilitating natural light penetration into interior spaces through reflective surfaces. This design not only enhances the visual quality of underground living but also promotes energy efficiency and sustainability.

Unique Approach to Light and Space

What distinguishes the Periscope project from many conventional architectural designs is its emphasis on utilizing reflections for daylighting. The modular system of mirrors incorporated in the roof directs sunlight into subterranean areas, creating bright and welcoming environments below ground level. This innovative strategy alleviates the common challenges associated with limited light in such spaces. Furthermore, the building incorporates careful planning of light wells and open atriums, contributing to natural ventilation and enhancing the overall spatial experience for occupants.

The functionality of the design is carefully articulated across various levels. The upper floor plans accommodate communal living areas and recreational facilities, while the lower levels serve as private residential units and services, ensuring a clear demarcation of public and private spaces. Each level is designed to maximize available space while maintaining a connection to the greenery on the surface, integrating features such as outdoor terraces and planter boxes that promote biodiversity.

Sustainable Material Use and Energy Efficiency

The Periscope project prioritizes sustainable material choices, using reinforced concrete for durability alongside glass for maximizing natural light. Sustainable wood finishes are employed internally, creating warmth and comfort within the spaces. The use of reflective metal panels enhances the building’s design and performance, reflecting light effectively and improving energy efficiency.

In addition to material consideration, the project includes energy-efficient systems that harness solar energy, allowing for reduced reliance on grid energy. The integration of green roof elements contributes to insulation while providing habitats for local fauna. This design not only limits environmental impact but also encourages occupants to engage with and appreciate their surrounding ecosystems.

As interest grows in sustainable building practices and innovative architectural designs, exploring the full presentation of the Periscope project can provide deeper insights into its architectural plans, spaces, and unique design solutions. Reviewing the architectural sections and details will reveal the intricate balance of form, function, and sustainability.

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.
