Timber Elements Elevated Above Pad Foundations in a Tree Trunk-Inspired Observation Tower

Project in-detail

Elevated on pad foundations, the tower's design mimics a tree trunk with vertical timber elements, creating a unique observation point that enhances the experience of the surrounding North Vidzeme Biosphere Reserve.
5 key facts about this project
01
Elevated structure minimizes ground disturbance in the biosphere.
02
Staggered floor plans mimic tree trunk rings for organic design.
03
Vertical timber elements enhance views while providing structural support.
04
Central steel core allows for unobstructed sightlines toward the landscape.
05
Localized pad foundations reduce construction impact on the environment.

The Kurgi Observational Tower is situated in the North Vidzeme Biosphere Reserve in Latvia, designed to provide a unique vantage point while respecting the local landscape. The tower functions as a place for observation, allowing visitors to connect with the natural surroundings. Its design is inspired by the form of a tree trunk, which helps it blend into the environment. The slender shape reduces visual disruption and invites exploration of the area.

Design Concept

The design reflects a strong connection to nature, focusing on harmony and simplicity. The tower features staggered floor plans that decrease in size as you move upward, resembling the rings found in a tree trunk. This configuration creates a dynamic spatial experience. Each upper level offers something different, cultivating an engaging environment for visitors.

Structural Elements

At the heart of the tower is a steel frame that supports all levels and includes a lift shaft. This structure ensures stability and safety while providing unobstructed views of the landscape. The use of vertical timber elements throughout the design reinforces the connection to the surrounding trees, enhancing the user experience with framed openings that draw attention to the scenery outside.

Foundation and Terrain Interaction

The tower is elevated on localized pad foundations, which allows it to sit above the ground and minimizes disturbance to the natural terrain. This thoughtful approach to construction helps preserve the site while reducing the need for heavy machinery during building. The foundation system highlights a commitment to coexistence with nature, making the tower feel less intrusive in its setting.

Lighting and Heating

Interior lighting is integrated through the use of vertically fixed fixtures that blend into the overall design. This choice reduces visual clutter and maintains a calming atmosphere for visitors. For warmth, the upper levels utilize an electrically powered radiant heat source. This approach efficiently provides comfort without taking up valuable space.

Carefully designed viewing platforms allow occupants to enjoy framed vistas of the rolling hills and dense forests. This connection with nature enhances the overall visitor experience, making interaction with the environment a central aspect of the tower’s purpose.

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.
