Grounded by a pedunculate oak, cellular concrete roots extend to create a contemplative space for remembrance, seamlessly integrating nature and memory in a well-defined memorial setting.
5 key facts about this project
01
A central feature is a mature pedunculate oak that symbolizes life and death.
02
Cellular concrete roots extend into the landscape, merging with nature over time.
03
Niches for urns are designed to accommodate flowers and candles for personal remembrance.
04
Integration of pleurocarpous moss reflects sustainable engagement with the environment.
05
The layout creates pathways that encourage visitors to engage thoughtfully with their memories.

The Columbarium - The Chamber of Memories is located in Latvia and explores themes of memory, nature, and cultural significance. Drawing from local mythology, particularly the idea of the 'Austras koks' or the tree of life and death, the design invites visitors to reflect on their experiences. The columbarium serves as a memorial space focusing on the oak tree, a symbol of interconnectedness in life and death.

Design Concept

At the center of the design, a pedunculate oak tree stands out. It acts as the main feature from which roots extend into the surrounding space. These roots represent the journey of life, creating pathways that direct visitors through the columbarium. The natural rise and fall of the roots fosters a peaceful environment, encouraging reflection as people wander through the area.

Niche Integration

Thoughtfully designed niches are incorporated into the structure to hold urns, allow for flowers, and provide flat surfaces for candles. Each niche is part of a larger narrative, merging personal remembrance with the collective experience of grief. The arrangement of these niches promotes a sense of tranquility, inviting visitors to engage with their memories in a thoughtful setting.

Material and Visual Treatment

Cellular concrete is used for the roots, designed to gradually blend with the natural surroundings. Over time, moss and small plants are expected to develop on the concrete, further connecting the structure to the landscape. This interaction highlights the relationship between memory and nature, creating a space that evolves visually while offering a calm atmosphere.

Final Detail

The columbarium's design culminates with roots intertwining with living elements, symbolizing the lasting connections we maintain with those we remember. The thoughtful integration of natural and structural components creates a place of quiet reflection, demonstrating the enduring bond between the living and the memories of the departed.

`
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.
