Amphibious Microhome Constructed with Recycled Aluminum and Enhanced Water Management Systems

Project in-detail

Utilizing recycled aluminum and an amphibious design, this microhome effectively addresses flooding challenges while maintaining sustainable living options through innovative water management systems.
5 key facts about this project
01
Utilizes expanded polyethylene for buoyancy during flood events.
02
Incorporates an innovative rainwater harvesting system with transparent tubing for user awareness.
03
Features low-E glass for thermal efficiency while maximizing natural light.
04
Constructed with durable high-performance concrete for flood resistance and stability.
05
Designed as an off-grid living solution with integrated solar panels for energy independence.

## Overview

The Urqucito project, designed to address contemporary challenges related to climate change, is an off-grid microhome located in flood-prone areas. Its focus on innovative water management and sustainability reflects a growing need for efficient housing solutions in environments affected by rising water levels and increased flooding. The architectural framework emphasizes an adaptive relationship with water, positioning it as both a challenge and a resource.

### Spatial Strategy and Structural Design

The structure features an angular silhouette characterized by slanted roofs and vertical planes, optimizing both water runoff during flooding and providing expansive views of the surrounding landscape. The design incorporates an "amphibious" strategy, allowing the dwelling to float during high water events while maintaining its structural integrity. This transitional interaction between the building and natural elements promotes a dynamic engagement with the environment.

### Material Selection and Sustainability

Incorporating a range of innovative materials, Urqucito emphasizes durability and sustainability. The roof and cladding utilize recycled aluminum for lightweight strength; an expanded polyethylene flotation system ensures buoyancy during severe weather; and high-performance concrete forms a resilient foundation to withstand floods. Sustainable insulation materials enhance energy efficiency, while low-emissivity glass windows contribute to thermal comfort, minimizing energy consumption.

### Water Management Systems

Urqucito integrates advanced water management features, including a comprehensive rainwater harvesting system that underscores water conservation efforts. The unique architectural design enables controlled water levels within a chamber during floods, enhancing safety while maintaining the dwelling's functionality. Additionally, an indoor water management system employs transparent tubing with colored LED indicators to promote awareness of water usage, encouraging responsible practices among residents. Equipped with solar panels and water recycling technologies, the microhome is capable of off-grid living, reinforcing its sustainability and resilience in various geographic contexts.

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.
