MODULAR TOWER FOR ECOLOGICAL OBSERVATION

Project in-detail

Located in the wetland landscape of Big Slough and Silver Lake, the design offers a vertical exploration of the natural environment through a carefully articulated watchtower structure. The project merges ecological awareness with spatial complexity, creating an architectural framework for observation, movement, and interaction.
5 key facts about this project
01
Crafted with charred wooden shingles, the exterior enhances durability and fire resistance.
02
Utilizes cross-laminated timber panels for both structural support and aesthetic warmth.
03
The modular design allows for dynamic spatial experiences across different levels.
04
Incorporates nesting spaces to support local wildlife and promote biodiversity.
05
Features a bent A-frame design to optimize sightlines towards Silver Lake and its surroundings.

Aether is situated in De Smet, South Dakota, within the ecological context of Big Slough and Silver Lake. Designed as a multi-level watchtower, the project facilitates observation, exploration, and educational engagement with the surrounding wetland environment. It aims to foster interaction between visitors and the landscape through a structure that emphasizes spatial diversity and environmental responsiveness.

Spatial strategy and circulation
The tower is composed of intersecting modular forms that generate a range of spatial experiences as users move vertically through the structure. Each level offers distinct vantage points, encouraging pause and reflection while supporting group activities. Circulation paths are varied and intuitive, promoting continuous movement and engagement for individuals and educational groups alike. The plan accommodates flexible gathering spaces and observation decks, organized to support both solitary and communal use.

Material expression and environmental response
A steel structural frame supports the tower’s shifting geometry while allowing openness and vertical articulation. Wooden slats clad key surfaces, introducing visual warmth and texture, and offering functional nesting zones for local wildlife. Transparent elements—primarily glass—enable unobstructed views and strengthen the visual connection between interior and exterior. Shading is integrated into the elevations to enhance comfort and reduce solar gain. The material palette and form are deployed to balance durability, environmental integration, and user experience.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
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.
