Petal-Inspired Observation Tower Crafted From Glulam and Straw Bales Integrating Into Wetland Ecosystem

Project in-detail

Crafted from glulam and straw bales, the observation tower's petal-like structure seamlessly integrates with the wetland ecosystem, providing visitors with an elevated platform for immersive birdwatching experiences.
5 key facts about this project
01
Crafted from locally sourced glulam and straw bales for enhanced sustainability.
02
Petal-like structural design allows for multiple observation platforms with varying sightlines.
03
Central steel core enables flexibility in the tower's outer shell while maintaining stability.
04
Natural ventilation integrated into the design promotes energy efficiency and comfort.
05
Strategically positioned to minimize disturbance to local wildlife during birdwatching activities.

The project under analysis is the Pape Bird Observation Tower, known as "SEED," located in Pape Nature Park, Latvia. This architectural design serves as a dedicated space for birdwatching, facilitating a deeper interaction between visitors and the natural environment. The tower is intended to enhance the visitor experience by providing unobstructed views of the surrounding wetlands, home to a diverse array of migratory bird species.

The SEED tower embodies the concept of growth and regeneration, mirroring the attributes of a seed in its form and design. The organic shape of the structure supports the functional needs of birdwatchers while integrating with the landscape. The design utilizes multiple observation platforms to allow visitors to engage with their surroundings from various vantage points.

Innovative Structural Elements The design incorporates several progressive structural elements that contribute to its unique architectural character. The use of vertical glulam fins provides stability and strength while contributing to the aesthetic appeal of the tower. A central core made of steel frames supports the overall structure, allowing for flexibility in the outer shell. The integration of straw bale panels not only enhances insulation but also provides a visually appealing facade that resonates with the natural setting.

The observation platforms within the tower are strategically arranged, enabling panoramic views of the wetlands, which is crucial for effective birdwatching. The architectural design prioritizes the observer’s experience, making it possible to view wildlife while minimizing disturbance to their habitat.

Sustainable Design Approach SEED distinguishes itself through its commitment to sustainability and eco-friendly practices. The selection of materials is a key aspect of this design approach. The use of locally sourced materials, such as glulam and straw bales, reflects a conscious effort to reduce environmental impact. Additionally, the architectural design facilitates natural ventilation and light, which contributes to the overall energy efficiency of the building.

The tower structure's relationship with the site enhances its environmental sensitivity. By carefully considering placement and orientation, the design ensures that visitors can enjoy the landscape without infringing on the wildlife's natural behavior.

For an in-depth exploration of the Pape Bird Observation Tower, including architectural plans, sections, and detailed designs, interested parties are encouraged to review the project presentation. Such materials provide valuable insights into the architectural ideas and technical considerations that shaped this innovative bird observation tower.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
