Recycled Shipping Containers Supporting Rainwater Collection in a Multifunctional Community Space

Project in-detail

Recycled shipping containers create a versatile community space that integrates a rainwater collection system, addressing both ecological sustainability and local agricultural needs.
5 key facts about this project
01
Recycled shipping containers form the main structure, promoting sustainable construction practices.
02
An integrated rainwater collection system supports both irrigation and local water needs.
03
The design features a protective membrane that shields the soil underneath from climatic extremes.
04
Vertical layering of functions enhances spatial efficiency while minimizing land use.
05
A canopy-like umbrella structure helps recreate humid conditions typical of the rainforest ecosystem.

The Skyforest project is located in Brazil and seeks to address the serious issue of rainforest damage caused by slash-and-burn farming. The design combines living space and agricultural functions in a central tower, promoting sustainable practices in a vulnerable ecosystem. It aims to bring together human needs and environmental care, creating a balanced approach to land use.

Design Concept

At the heart of the design is a vertical structure that minimizes impact on the land while making the best use of available space. Different activities are stacked in layers, including areas for farming, administration, and community living. This arrangement supports effective practices and encourages interaction among residents. The tower operates as a single unit, fulfilling various needs for those who inhabit it.

Water Management System

An important aspect of Skyforest is its water management system. The building features a water tower that captures rainwater through an umbrella-like design. This collected water is redirected into nearby rivers and also used for irrigation. By ensuring a reliable water source, the system aids in sustainable agriculture, helping to maintain crop productivity and support local wildlife.

Protective Features

The structure is wrapped in a protective membrane that shields it from harsh conditions like intense sunlight and heavy rains. This feature helps to safeguard the soil beneath the tower while creating a stable environment inside. The umbrella structure allows for optimal conditions for plant growth, reflecting a commitment to restoring the ecosystem.

Materiality

The central tower is built primarily from recycled shipping containers, highlighting a sustainable method of construction. This choice reduces the impact of building new materials and promotes efficient use of existing resources. The modular nature of shipping containers allows for flexibility in design, ensuring the living spaces are functional and adaptable.

The visual form of the tower resembles the protective canopies found in natural rainforests, helping it blend with the surrounding landscape. This design choice enhances its environmental role, connecting architecture with nature.

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.
