Incorporating a home sewage treatment system and PEX pipes, the design enhances ecological sensitivity while providing a multifunctional space for community engagement and plant cultivation.
5 key facts about this project
01
Incorporates a home sewage treatment plant with absorbent wells for eco-friendly waste management.
02
Features a greenhouse designed for year-round plant cultivation and community interaction.
03
Utilizes PEX pipes under dark roofing for efficient heating water circulation.
04
Eliminates architectural barriers to ensure full accessibility for all users.
05
Includes a green roof terrace that enhances insulation and provides a quiet outdoor space.

The design reflects a thoughtful approach to sustainability and community living, integrating functional spaces that serve both residents and visitors. Located in an area that values ecological considerations, the building features a greenhouse as a core element of its design. The overall concept combines energy efficiency and accessibility, meeting the needs of diverse users while being mindful of the natural environment.

Ecological Integration

The design makes sustainability a priority through innovative energy solutions. A greenhouse is positioned on the southern side of the building to take advantage of sunlight, allowing for maximum solar gain. This strategy is enhanced by a heating water system located under a dark roofing surface, which helps absorb and distribute heat effectively throughout the space.

Water Management

To further the commitment to sustainability, the northern side of the building includes a home sewage treatment plant and absorbent wells. This system reduces sewage output and repurposes treated wastewater for use in the greenhouse, promoting efficient water usage. By incorporating natural processes into the building's operation, the design fosters a balance between built and natural environments.

Accessibility and Spatial Organization

The layout clearly separates public and private areas to serve various functions. The ground floor acts as a public space, designed with service zones, a workshop, and access to the greenhouse. It includes a reception area and utility spaces that facilitate community activities. The workshop is adaptable, with movable partitions that allow it to be used for different purposes.

On the first floor, private zones are established to provide guest accommodations. This level features serving rooms, day zones, and hotel spaces, promoting comfort and privacy. A green roof terrace above the greenhouse not only adds insulation but also creates an inviting outdoor area, offering a place for residents to connect with nature.

Design Detail

A notable aspect of the project is the use of PEX pipes in the heating system, installed beneath the dark roofing. This setup enhances heating efficiency by allowing heat to transfer quickly and effectively. Such design considerations reflect a commitment to managing resources wisely while creating a functional living environment that supports both ecological and community needs.

`
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.
