Sustaining energy efficiency through a unique combination of a green roof and a ventilated facade with high-performance glass, the design creates a versatile living space that integrates seamlessly with urban life in Timişoara.
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.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
