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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
