5 key facts about this project
01
Elevated structure reduces environmental impact and concrete use.
02
Continuous thermal insulation enhances energy efficiency throughout the building.
03
The green roof integrates rainwater filtration and storage systems.
04
High-performance glass windows optimize thermal energy gain and shading.
05
Flexible living spaces adapt to individual occupant needs and activities.

The design focuses on sustainable urban living in Timişoara, Romania. It addresses environmental challenges while catering to the local community's needs. The building is elevated to reduce its ecological impact and minimize the use of concrete, aligning with modern principles of resource efficiency. Overall, the concept emphasizes energy conservation and adaptability in residential spaces, offering flexibility for various lifestyles.

Sustainability and Energy Efficiency

The building features a continuous thermal insulation system made from sandwich panels with wood and batt insulation, enhancing energy performance. High-performance glass windows are strategically placed to gather heat during colder months. In warmer seasons, exterior frames provide shade. Solar panels on the roof are an essential part of the design, serving as a renewable energy source that supports the project's sustainable focus.

Green Infrastructure

A significant aspect of the design is the green roof, which improves visual appeal and serves an important environmental function. This roof filters and stores rainwater in underground tanks, promoting effective water management. Treated wood panels create ventilated facades that maintain good air quality indoors. The facades not only provide functionality but also contribute to the aesthetic character of the building.

Flexible Living Spaces

Inside, the layout supports adaptability with spaces that can change based on the occupants' needs. Wet areas such as kitchens, bathrooms, and laundry rooms are grouped for better organization and efficiency. The main living area is designed for multiple uses, allowing for easy shifts between work, relaxation, and sleep. Movable dividers enhance this flexibility, helping to maintain a sense of community while offering privacy.

Attention to local materials is evident, particularly in the use of wood, which supports the regional economy and reduces transport-related emissions. The careful choice of materials and the focus on energy-efficient systems result in a residence that is environmentally mindful. The design's integration of green elements connects the structure to its surroundings, fostering a greater harmony with nature.

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.
