Tensegrity Structure Embraces Corten Steel and Ecological Water Collection

Project in-detail

Utilizing a tensegrity structure and Corten steel, the design integrates a water-collecting system that supports local vegetation while providing a multifunctional observation space for visitors and horses.
5 key facts about this project
01
Utilizes a tensegrity structure to minimize material usage while maximizing stability.
02
Incorporates a water-collecting system that nourishes local vegetation.
03
First platform design enhances visitor interaction without disturbing horses below.
04
Constructed with Corten steel, developing a unique patina over time.
05
Circular form allows for sweeping 360-degree views of the surrounding landscape.

The Kurgi Observation Tower is located within the North Vidzeme Biosphere Reserve, designed to complement the surrounding swamp and forest landscapes. It serves as a viewpoint for visitors and a shelter for horses, highlighting a connection between the built environment and nature. The design aims to reflect the characteristics of large trees, creating a structure that fits well within its setting while offering functional spaces for both humans and animals.

Materials and Construction

The tower features a lightweight Corten steel structure, known for its durability and weather resistance. Over time, it develops a natural patina that helps it blend into the environment. The design uses a tensegrity construction method, where the balance of tension and compression creates a stable form with less material. This approach not only enhances strength but also results in a visually striking presence that feels both lightweight and substantial.

Water-Collecting System

A key aspect of the design is the water-collecting system integrated into the structure. Rainwater is captured and channeled into an underground reservoir. From there, it is distributed to a pond that supports local plant life. This system reflects a commitment to sustainability, showing how design can enhance environmental function. The tower does more than provide views; it actively contributes to the health of the surrounding ecosystem.

Visitor Experience and Accessibility

Visitors experience the tower through tiered platforms that allow for observation while offering shaded areas for horses below. The first platform is wider, promoting stability and creating an inviting space. Access is facilitated either via a ramp staircase or an elevator. This dual approach ensures everyone can reach the observation area, enhancing the engagement with the natural surroundings.

Spatial Dynamics

The circular design permits a 360-degree view, encouraging visitors to appreciate the diversity of the biosphere reserve. Daylight filters through the structure, creating changing patterns of light and shadow that enrich the spatial experience. The design fosters a connection between visitors and nature, reflecting an intention to blend human activity with the landscape in a meaningful way.

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.
