The ADA House Microhomes project is located in the Rufina Alfaro district of Panama, a place that combines nature and community. The design focuses on providing practical living solutions while connecting with the surrounding environment. The concept features a geometric shape with a sloped roof that effectively handles rainwater and captures sunlight. This compact living space combines style with functionality, promoting a sustainable way of life.

Design Concept

The layout is modular, offering flexibility in a small area. It includes vital living spaces such as a living room, kitchen, bathroom, and bedroom arranged for easy movement. Each area serves its purpose while contributing to a bright and open atmosphere. This design ensures comfort and convenience for everyday living without feeling cramped.

Relationship with Environment

The placement of the microhome encourages a connection with its natural surroundings, benefiting both residents and the local ecosystem. By incorporating elements from nearby forests and gardens, the design fosters an indoor-outdoor relationship. Priority is given to natural light and airflow, creating a pleasant living environment that relies less on mechanical cooling or heating.

Materials and Sustainability

Materials for the ADA House consist of metallic flashing, grass, topsoil, geotextile sheets, drain cells, geomembranes, and concrete slabs. Synthetic wood is used for ceilings and cladding to provide warmth. Insulating panels improve temperature control and reduce noise, making the spaces more livable. The design also includes a rainwater harvesting system, which helps supply water for gardening and toilets, highlighting the focus on sustainability.

Functional Design Elements

Inside, the focus on multifunctional furniture ensures that space is used effectively. Features can be rearranged to fit different needs, making the living experience adaptable. The design manages to balance shared and private areas, encouraging interaction while allowing personal space.

A key highlight is the roofed terrace, which offers protection from the weather while providing an enjoyable outdoor area for relaxation and social activities. This detail not only adds value to the living experience but also creates an inviting connection to the outdoor environment.

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.
