Canopy Home Integrating Rainwater Collection in a Rainforest Ecosystem

Project in-detail

The microhome’s design incorporates a large canopy for rainwater collection while seamlessly integrating into the rainforest ecosystem, providing an efficient living space for biologists conducting research.
5 key facts about this project
01
The microhome features a footprint derived from the negative space of the rainforest canopy.
02
A large canopy directs rainwater to a central collection point for efficient resource use.
03
The design incorporates a compost toilet system to support sustainable waste management.
04
The structure emphasizes open views to facilitate continuous observation of the ecosystem.
05
No trees were cleared during construction, ensuring minimal ecological disruption.

Canomes is an architectural solution designed for rainforest environments, aimed specifically at biologists conducting research. The microhome focuses on ecological sustainability, fitting naturally into the landscape while minimizing its environmental impact. Located in the Congo Forest, the design responds to the area's hot and humid climate with regular rainfall, which plays a significant role in how the structure functions.

Design Concept

The concept behind Canomes centers on a compact living space measuring 25m². The footprint is derived from the negative space of the rainforest canopy, ensuring that the microhome does not disturb the trees surrounding it. This careful planning allows the structure to coexist with the existing ecosystem without requiring any clearing. The open layout offers wide views of the landscape, enhancing the experience for residents.

Canopy and Water Management

A key feature of the microhome is its generous canopy. This element provides protection from the weather and functions as a rainwater collection system. The design channels rainwater toward a central collection point, allowing for effective management of this vital resource. The ability to collect, filter, and use rainwater highlights the project's focus on sustainability and resource efficiency.

Waste Management System

Waste management is addressed through a compost toilet system. Within this design, biological waste is processed in a contained bio-drum, which facilitates composting for use in the surrounding area. This approach not only reduces the environmental footprint of the microhome but also showcases a commitment to sustainable living. The system supports the health of the local ecosystem while allowing residents to engage with the natural environment.

Spatial Engagement

The layout of Canomes is carefully designed to encourage interaction with the vibrant forest ecosystem. Large openings connect the microhome to the landscape, allowing biologists to observe their surroundings closely. This connection is fundamental for those using the microhome, as it promotes both scientific research and a deeper appreciation for the nature that surrounds them. The canopy’s design is not only practical for collecting rainwater; its shape also reflects the flowing forms found in the rainforest.

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.
