Spiral Viewing Platform Crafted From Weathering Steel and Lattice Wood Framework

Project in-detail

Crafted from a unique combination of weathering steel and a lattice wood framework, this spiral observation tower offers dynamic perspectives of the surrounding North Vidzeme Biosphere Reserve while fostering an immersive visitor experience with nature.
5 key facts about this project
01
Crafted from a lattice wood framework that enhances transparency and light.
02
Incorporates weathering steel for durability and minimal maintenance.
03
Features a spiral staircase that offers continuous changing perspectives.
04
Includes contemplative platform areas designed for quiet reflection.
05
Integrates seamlessly into the North Vidzeme Biosphere Reserve landscape.

The "Captured Spire" is an observation tower located in the North Vidzeme Biosphere Reserve. This architectural project serves multiple functions, including providing panoramic views, enhancing visitor engagement with the natural environment, and promoting an appreciation for the local ecology. Its design emphasizes a seamless integration with the landscape, inviting users to explore and observe the surrounding nature from varying heights and perspectives.

The architectural structure features a unique spiral design, which encourages visitors to ascend gradually while experiencing shifting viewpoints of the forest and fields below. The use of a lattice framework not only supports the tower but also allows for transparency and interaction with the environment. As visitors climb the spiral staircase, they move between dynamic areas of activity and static zones designed for contemplation.

The materials chosen for the project enhance its functionality and aesthetic appeal. Wood serves as the primary material for the lattice structure, reflecting sustainability values and providing warmth to the overall design. Steel offers durability, while glass is incorporated for enhanced visibility and natural light infiltration. Weathering steel has been specifically utilized in the staircase design to ensure resilience against the elements. Additionally, cast zinc is used in the shading components to effectively manage thermal gain.

Unique Design Approaches

The "Captured Spire" distinguishes itself from traditional observation towers through its focus on interactivity and user experience. The design promotes active engagement with the surrounding landscape, encouraging visitors to explore their environment from a variety of perspectives. This approach not only enhances the observational experience but also fosters a deeper connection with nature.

The integration of functional areas, such as viewing platforms and contemplative spaces, creates a contrasting rhythm between movement and stillness. This design methodology aligns with the project's goal of providing a holistic experience that transcends mere observation. The careful selection of materials further reinforces the project's sustainability mission while enhancing aesthetic continuity with the environment.

Architectural Details and Structural Integrity

The project’s architectural details contribute significantly to its overall impact. The dynamic form of the lattice structure plays a crucial role in allowing natural light to filter through while maintaining structural integrity. The spiral staircase invites exploration, with each ascent revealing new vistas that encourage visitors to engage with their surroundings.

The platform areas serve as resting points, where users can take a moment to appreciate the views in a static environment. This duality of movement and stillness forms an integral part of the user experience, making the "Captured Spire" not just an observation tower but a space for reflection and connection with nature.

To gain deeper insights into the architectural plans, sections, and ideas that inform the design of the "Captured Spire," explore the project presentation for additional details. Understanding these elements will provide a comprehensive perspective on the architectural methods and principles that define this engaging structure.

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
