Elevating community interaction through its cylindrical form and galvanized steel cladding, the observation tower offers panoramic views of the surrounding landscape while embracing the region's agricultural heritage.
5 key facts about this project
01
Constructed with galvanized steel, the tower features weather-resistant qualities suited for the local climate.
02
The cylindrical design optimizes structural stability and enhances panoramic views for visitors.
03
A central spiral staircase maximizes space efficiency while ensuring accessibility for all users.
04
Perforated mesh fabric wrap provides shading and safety while maintaining visual transparency.
05
The tower's integration with the landscape fosters local wildlife observation without disturbing natural habitats.

### Overview

Situated in De Smet, South Dakota, the Observation Tower is designed to reflect the region's agricultural heritage while integrating contemporary architectural practices. Its form draws inspiration from traditional Midwest grain silos, providing a modern interpretation that aligns with local identity. The project endeavors to create a functional observation space that enhances the connection between architecture and the surrounding landscape.

### Morphological and Functional Strategy

The tower's design features a series of stacked cylindrical elements, effectively emulating the silhouette of historical grain silos. This morphological approach not only maximizes the potential for panoramic views but also maintains structural integrity through strategic extrusions and voids. A central spiral staircase supported by a singular foundational column minimizes site disturbance, enhancing access for all visitors, including various media installations to accommodate individuals with disabilities.

### Materiality and Environmental Integration

Materials selected for the tower prioritize durability and local availability, reinforcing the cultural context of De Smet. Galvanized steel tread plates provide strength for the stairways, while corrugated steel cladding references traditional agricultural structures, optimizing performance against local climatic conditions. A light-gauge steel framework minimizes overall weight while preserving strength. Additionally, a perforated mesh fabric wrap enhances the visual aesthetics and serves functional purposes such as shading and safety within the observation decks. This material approach not only respects the agricultural heritage but also facilitates a sustainable interaction with the natural ecosystem, allowing for unobtrusive wildlife observation.

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.
