Metal Tiles and Modular Shapes in Sustainable Brazilian Living

Project in-detail

With its innovative use of metal tiles and efficient modular layouts, the design reduces space consumption while promoting sustainable living for residents in a hot Brazilian climate.
5 key facts about this project
01
Reduces building area from 36,000 square meters to 9,000 square meters, accommodating the same number of residents.
02
Features an elongated rectangular form measuring 2.6 by 9.6 meters for optimal interior space usage.
03
Incorporates a rainwater reuse system to enhance water sustainability and efficiency.
04
Uses a ventilation system in the roof and facade to improve thermal comfort in a hot climate.
05
Employs a modular construction approach for efficient assembly and easier maintenance.

The condominium design in Brazil addresses both the reduction of space and the need for environmental sustainability. By decreasing the occupied area significantly from 36,000 square meters to just 9,000 square meters, the project allows for the same number of residents while promoting better land use. The focus is on creating a living environment that connects with nature and responds thoughtfully to the local climate.

Spatial Efficiency

The design features residential units in an elongated rectangular shape, measuring 2.6 by 9.6 meters. This configuration maximizes interior space, making it practical for everyday living. The layout also allows the living room and kitchen to blend with an outdoor deck, encouraging interaction with the natural surroundings. The goal is to make a home that feels open and inviting.

Climate Responsiveness

In a hot and humid Brazilian climate, thermal comfort is crucial. The design incorporates a roof that allows for ventilation between the metal tile and the slab. This setup helps reduce heat buildup and keeps the interior cooler. The facade also uses a ventilation system to promote airflow, ensuring a comfortable living environment throughout the year.

Sustainable Resource Management

A standout feature of the design is its rainwater reuse system. This system can significantly lessen reliance on conventional water supplies, especially during rainy periods. By collecting and utilizing rainwater, residents can contribute to sustainability efforts while enjoying a practical solution to water management. This feature aligns with a broader commitment to eco-friendly living.

Modular Construction Approach

The project adopts a modular construction approach, which allows for staged work and the use of pre-fabricated components. This method improves the efficiency of construction and simplifies future maintenance. By promoting fast assembly and quality control, this approach reflects a modern trend in residential architecture that prioritizes durability and easy upkeep.

The roof's metal tiles not only support thermal regulation, but also enhance the overall longevity of the structure, making it a practical option for urban living. This thoughtful design carefully balances residential needs with environmental awareness.

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.
