The residential project in Comuna 13, Medellín, offers a thoughtful response to the need for affordable housing in an area known for its challenges. Designed with young residents in mind, the building aims to create a safer and more vibrant community space. The emphasis is on practical living, using a core-based structure that allows for varied spatial arrangements and enhances life within the apartments.

Design Concept

The layout divides the building into specific functional zones, each catering to different daily activities. The sanitary zone includes essential utilities, while the storage area provides ample space for personal belongings. The cooking zone is strategically placed next to an expansive window, offering views and a social dining experience. This arrangement not only supports everyday living but also fosters interaction among residents.



Unique Features

The project includes elevated windows that sit three meters above the ground. This design choice enhances both privacy and security, allowing plenty of natural light to enter the spaces. Manually adjustable shutters provide additional safety and help with airflow, creating a comfortable indoor environment. These elements highlight the careful consideration given to the living experience in a busy urban setting.



Structural Considerations

A reinforced concrete shaft serves as the primary structural element of the building. This design choice, anchored by columnar foundations, ensures stability and longevity. The sloped roof is pitched at 20 degrees, which helps collect rainwater efficiently. This aspect of the architecture supports sustainable practices and aligns with the ongoing efforts to improve Comuna 13's urban landscape.



Sustainability Initiatives

The project incorporates several sustainability features. Solar panels are placed on the roof, oriented towards the south and west, to maximize energy efficiency. A water collection and filtration system captures rainwater for reuse, further contributing to eco-friendliness. Additionally, the building includes a waste management strategy that separates materials into organic, mixed, plastic, paper, and glass categories, encouraging thoughtful disposal habits among residents.



Energy-efficient LED lighting enhances both the interior atmosphere and the building's overall functionality. This focus on careful illumination contributes to creating a warm and inviting environment, further supporting the aim of fostering a strong sense of community within the neighborhood.

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.
