The Spiraling Observation Tower

Project in-detail

The design responds to the need for enhanced interaction between visitors and the surrounding natural environment by providing elevated observation points within a wetland setting. It integrates with the existing trail system to support wildlife viewing and outdoor recreation.
5 key facts about this project
01
Utilizes cross-laminated timber panels for structural efficiency and sustainability.
02
Features charred wooden shingles to enhance durability and aesthetics.
03
Incorporates a bent A-frame design to optimize views of surrounding wetlands.
04
Designed with dual platforms for diverse wildlife observation opportunities.
05
Connects seamlessly to existing trail systems, promoting ecological awareness.

Located near Big Slough and Silver Lake, the design functions as a multi-use observation tower integrated within the existing trail network. It aims to facilitate wildlife viewing while encouraging visitor interaction with the natural environment through architectural elements that respect the surrounding ecosystem.

 

Spatial Configuration and User Experience  

The tower features a spiraling form that guides visitors on a gradual ascent, reflecting natural movement patterns within the landscape. Two main platforms are incorporated: an inner platform providing space for relaxation and wildlife observation, and a peak viewing platform dedicated to unobstructed observation. Circulation is managed via a secure staircase designed for accessibility, while concrete foundations ensure structural stability. Glass panels in the upper viewing areas allow for clear sightlines over the wetlands.

 

Materiality and Sustainability  

Cross-Laminated Timber (CLT) is the primary construction material, chosen for its structural performance and environmental benefits. The timber imparts a warm presence within the natural context, aligning with sustainability goals. Varying platform heights create diverse observation opportunities, supporting multiple forms of engagement with the ecosystem.

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.
