Cantilevered Structure Crafted From Ultra-Lightweight Concrete and Natural Wood Panels Inhabiting A Volcanic Landscape

Project in-detail

Constructed with ultra-lightweight concrete and local wood, the cantilevered tower harmonizes with its volcanic surroundings to serve as a multifaceted observational space for visitors.
5 key facts about this project
01
Cantilevered structure allows for unobstructed views from multiple levels.
02
Used ultra-lightweight concrete to minimize environmental impact on the site.
03
Incorporates a lattice framework designed to enhance structural transparency.
04
Features open-frame design that fosters a seamless connection with nature.
05
Constructed using locally sourced materials to promote sustainability.

The architectural project "Double Negative" serves as a unique observational tower situated within a volcanic landscape. Its design integrates seamlessly with the surroundings, emphasizing both the architectural form and the natural context. Intended to offer visitors a panoramic view of the area, the structure embodies a careful balance between built elements and the landscape, allowing users to engage deeply with their environment.

Unique Concept and Functionality
"Double Negative" represents an exploration of absence and presence through architectural form. The design reflects the duality of human interaction with nature, creating a space that is both inviting and contemplative. The observational tower serves as a gathering point for visitors, enabling them to experience the terrain from multiple vantage points. Its design encourages a physical journey upwards, enhancing the sensory experience as visitors ascend through the structure.

Distinct Design Approaches
The project stands out due to its innovative use of materials and structural systems. Lightweight concrete is employed for the main structure, reinforcing durability while minimizing the physical footprint on the site. The choice of wood for the framework introduces warmth and aligns the architecture with the natural elements of the landscape. Metal components are incorporated for stability, providing essential support while maintaining a sleek aesthetic.

The vertical configuration of the tower facilitates a unique spatial journey. Open observational areas throughout the structure allow for expansive views and encourage engagement with the landscape. The design draws inspiration from natural fissures and caverns, employing textured facades that mimic geological patterns. This thoughtful approach fosters a connection between the tower and its environment, enhancing the visitor experience.

Architectural Details and Elements
"Double Negative" features a lattice framework that underscores the interplay of solidity and void. This design method promotes safety while allowing for transparency, promoting visual connection to the exterior landscape. Bracing cables anchor the structure, ensuring stability in the face of environmental challenges. The integration of sustainable construction practices and local resources further minimizes the project's ecological impact, reinforcing the relationship between architecture and its site.

For those interested in a deeper understanding of "Double Negative," explore various aspects of the project, including architectural plans, architectural sections, architectural designs, and architectural ideas. Each of these elements provides insight into the project's thoughtful design and functional considerations.

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.
