Set against the backdrop of the Great Kemeri Bog, the use of Cor-Ten steel and glass facades creates a dialogue with the natural landscape, enhancing the visitor experience while serving as an educational center focused on wetland ecology.
5 key facts about this project

The building integrates bio-swales for natural stormwater management.
02
Cor-Ten steel is used for both durability and aesthetic harmony with the landscape.
03
A roof garden features sedum planting to enhance biodiversity.
04

05
Boardwalks guide visitors seamlessly through the wetland landscape.

The Great Kemeri Bog Visitors Center is located near Riga, Latvia, at the entrance of the national park. It serves as a key facility for visitors, providing spaces that enhance their understanding and appreciation of the surrounding ecology. The design emphasizes a connection between the building and the landscape, inviting guests to engage with the natural world.

Architectural Concept

The center’s design draws from the existing boardwalks that traverse the bog, creating a pathway that guides visitors through the wetland landscape. This arrangement highlights exploration and movement, allowing people to experience different facets of the environment. The boardwalks create a flow that encourages visitors to engage with nature in a direct way.

Site Features

As visitors approach the center, they encounter raised bio-swales that have both functional and aesthetic roles. These swales manage stormwater and support the growth of native wetland plants. This design choice not only enhances the entrance experience but also contributes to the ecological health of the area. The integration of these natural elements reflects a commitment to sustainability and environmental sensitivity.

Functional Spaces

Inside the building, different areas are organized to support both public visitors and staff. An information station greets guests and provides essential information about the park. Nearby, a café offers a space to relax and enjoy refreshments while taking in views of the landscape. The layout of these spaces makes effective use of natural light, especially in the café, where sunlight is maximized during the morning hours. This thoughtful arrangement enhances comfort and encourages social interaction.

Materiality and Design Details

Weathering steel, specifically Cor-Ten steel, plays an important role in the building’s design. This material is selected for its distinctive, rustic appearance, which harmonizes with the natural colors of the environment. As it rusts, it develops a protective layer that helps it blend into the landscape. Glass curtain wall facades also feature prominently, reflecting the beauty of the surrounding forest and creating a dialogue between the indoors and outdoors.

The roof garden, planted with sedum, adds to the project’s connection to nature. It provides a space for visitors to enjoy views from above, contributing to local biodiversity while offering an inviting area for relaxation. This feature demonstrates a blend of functional design and respect for ecological systems, allowing visitors to engage with the environment in a meaningful way.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
