Suspended Structure Embracing Natural Ventilation and Terraced Vegetation

Project in-detail

Suspended from the cliffside, the structure leverages natural ventilation through chimney-like voids while incorporating terraces for vegetation, providing multifunctional spaces that adapt to user needs.
5 key facts about this project
01
Suspended from a cliffside, minimizing ground impact.
02
Incorporates chimney-like voids for natural ventilation.
03
Features terraces designed to support diverse vegetation.
04
Utilizes rainwater for cooling and energy generation.
05
Integrates photovoltaic layers on the façade for solar energy.

The Cliff is located on the slope of Sugarloaf Mountain in Rio de Janeiro, Brazil. It integrates with the natural environment, using the mountain's contours to rethink how buildings can be supported. By hanging from the cliff rather than standing on the ground, it reduces risks from moisture while providing flexible spaces that can be adapted for different uses. This approach encourages a close connection with nature, enhancing the overall design.

Design Integration

The concept focuses on blending the structure with the landscape. The building's suspension system protects it from soil-related issues while creating a visual bond with the mountain. This vertical element strengthens the relationship between the building and its surroundings, allowing it to harmonize with the unique topography of the area rather than overshadowing it.

Environmental Systems

Operational efficiency is a key aspect of The Cliff. It features adaptable open spaces designed to meet the needs of users. Natural wind currents are channeled through chimney-like voids, promoting airflow and cooling without relying heavily on mechanical systems.

Water management is integrated into the design, with rainwater collected and stored in tanks located behind the main structure. This water serves multiple functions: it cools the interior, provides energy through turbines, and supports plants on the terraces, enhancing air quality indoors.

Use of Solar Energy

Solar energy collection occurs through photovoltaic layers on the glazing. These panels not only produce power but also provide shade to control heat gain inside the building. This practical approach highlights the design's response to the local climate, which includes heavy rainfall and strong sunlight.

A distinctive feature is the external terraces that break up the building's bulk. These outdoor areas create opportunities for interaction with the natural landscape. They also serve practical purposes, allowing vegetation to thrive, which contributes to the overall environmental strategy of the project.

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.
