02
Incorporates laminated veneer lumber for enhanced durability and environmental resistance.
03
Features a spiral design that mimics the dynamics of avian flight patterns.
04
Includes a seasonal phenology clock to track migratory bird timings through shadow patterns.
05
Access is optimized with ADA-compliant ramps and spacious viewing platforms for inclusivity.
The Hollow is an architectural project designed as a bird viewing tower situated at the Lake Pape Nature Preserve. This structure serves a dual purpose of providing an observational platform for birdwatching while integrating seamlessly into the surrounding environment. The design embodies a commitment to sustainability and ecological sensitivity, promoting an enhanced connection with nature.

Structurally, The Hollow features a unique spiral shape that draws inspiration from avian anatomy. This form allows visitors to ascend gradually, mimicking the flight of birds and providing expansive views of the natural landscape. The design incorporates features that facilitate both individual and group observations, enhancing the overall experience for visitors.

Structural and Aesthetic Attributes

The primary structural components of The Hollow include braided steel cables, laminated veneer lumber, and high-strength tubular steel poles. The use of braided steel cables allows for a lightweight yet robust framework that supports the tower's spiraling form. Laminated veneer lumber serves as the foundation, chosen for its durability and resistance to environmental conditions. Low-cost lumber planks are used for walkways and viewing platforms, providing a natural finish that blends with the landscape.

The tower's design integrates significant interactive elements, including platforms that accommodate multiple observers. Each platform is designed for optimum visibility and comfort, encouraging exploration and extended stays in the tower. The incorporation of a seasonal phenology clock is a notable feature, allowing sunlight to cast shadows that indicate seasonal bird migration patterns. This practical detail not only enhances the architecture but also serves an educational purpose for users.

Innovative Design Approaches

The Hollow differentiates itself through its thoughtful approach to accessibility and community engagement. The design includes ADA-compliant ramps and wide viewing areas, ensuring that people of all abilities can access the tower. This focus on inclusivity extends the tower’s utility as a communal resource.

Furthermore, the project emphasizes the use of sustainable materials that minimize ecological impact while offering longevity and durability. This careful selection reflects a modern approach to architecture that balances aesthetic goals with environmental responsibility.

The integration of design elements that harmonize with the ecological context of the Lake Pape Nature Preserve distinguishes The Hollow from typical bird observation structures. Architectural strategies that prioritize interaction with the landscape demonstrate a forward-thinking approach to nature-based architecture.

To explore the comprehensive architectural plans, sections, and design details of The Hollow, consider reviewing the project's presentation for a more in-depth understanding of its architectural ideas and unique features.

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.
