Spiral Steel Structure Embracing Natural Light Through Expansive Glass and Sustainable Design

Project in-detail

The spiral steel framework interwoven with expansive glass panels captures natural light while providing panoramic views, creating a functional observation tower that seamlessly integrates into the landscape of the North Latvia Livonian Reserve.
5 key facts about this project
01
The design mimics the organic movement of grass, resulting in a fluid spiral form.
02
Large glass panels enhance visibility while allowing natural light to permeate the interior.
03
Sustainable features include solar panels and a rainwater collection system.
04
A central spiral staircase facilitates movement and offers framed landscape views.
05
The structure is carefully positioned to harmonize with the surrounding topography.
Zāles Tornis is an architectural project located within the North Latvia Livonian Reserve, designed to engage with the surrounding landscape through a unique spiral form. The structure is a representation of organic architecture, reflecting the movement and rhythm of grass as it sways in response to the wind. Zāles Tornis serves as a viewing tower, facilitating observation and interaction with the natural environment, making it a functional part of the reserve's visitor experience.

The architectural design incorporates various levels, each providing distinct viewpoints of the surrounding terrain. These viewing platforms not only enhance the experience of the landscape but also reinforce the connection between the built environment and nature. The tower’s height and design allow for significant visibility, encouraging exploration and engagement from visitors. The building’s form is achieved through a steel framework, ensuring structural integrity while allowing for open, unobstructed views through large glass panels.

Sustainability is a pivotal aspect of the project, with features that include solar panels for energy efficiency and a rainwater collection system. These elements align with contemporary architectural practices focused on ecological responsibility. The use of decorative metal screens provides shading and visual interest, further enhancing the tower’s overall composition.

Dynamic Spiral Design
Zāles Tornis distinguishes itself through its spiral design, which departs from conventional architectural forms typical in viewing towers. This organic, fluid shape allows for ease of circulation via a central spiral staircase, promoting movement between levels. The staircase itself becomes an integral part of the architectural experience, guiding visitors upward while simultaneously offering framed views of the landscape through cut-out sections.

The combination of materials—steel, glass, and concrete, along with sustainable systems—supports the project’s ambition to harmonize with its environment. The façade made of glass not only allows natural light to penetrate the interior spaces but also creates a seamless visual connection between the inside and the outside, enhancing the overall sensory experience.

Integration with Natural Environment
The placement and orientation of Zāles Tornis further exemplify its integration with the natural surroundings. The design responds to the topography of the site, ensuring that the tower's height complements the surrounding trees and landscape. The architectural approach emphasizes a minimal footprint, allowing the natural environment to remain the focal point. The consideration of vantage points around the tower enriches the visitor experience, making the exploration of the landscape interactive.

The project embodies a contemporary architectural ethos by merging form, function, and sustainability. The innovative responses to environmental challenges and design intricacies make Zāles Tornis a noteworthy example in the realm of architecture. This project is a compelling case study in how thoughtful design can create meaningful connections with nature.

For those interested in a deeper understanding of the architectural concepts and methodologies employed in Zāles Tornis, it is encouraged to review the architectural plans, sections, and detailed designs associated with this project. The presentation offers insight into the architectural ideas that informed each aspect of the design and can serve as a valuable resource for further exploration.

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.
