Rainwater collection and earth insulation define a microhome in Zlatibor, blending traditional wooden beams with modern sustainability to create an efficient residential space.
5 key facts about this project
01
Rainwater collection system integrated into the design for enhanced resource efficiency.
02
Earth filling used for thermal insulation, reflecting local building practices.
03
Large southern glass wall maximizes natural light and minimizes energy use.
04
Partial basement embedding reduces visual impact and promotes landscape harmony.
05
Utilization of local timber materials strengthens community connections and cultural relevance.

The Microhome project is situated in the Zlatibor mountain region of Serbia, where it takes a fresh look at traditional Serbian housing. The design focuses on blending with the surrounding landscape and responding to the area's climate while providing a functional living environment. It draws on local cultural elements, resulting in a structure that meets modern needs while honoring its roots.

Design Concept

The concept is rooted in the use of local materials, reflecting the region's architectural heritage. Wooden planks and horizontal wooden beams form the backbone of the structure, connecting it to the traditional building practices of the area. Earth filling adds thermal insulation, while plasterboard finishes provide a modern touch. By using these materials, the design respects cultural identity while enhancing energy performance.

Environmental Integration

The alpine and sub-alpine climate of Zlatibor has a significant impact on the building's orientation. The structure is carefully placed to capture as much natural light as possible, which helps reduce energy consumption. A large glass wall facing south allows daylight to fill the interior, minimizing the need for artificial lighting and contributing to a comfortable living environment throughout the year.

Sustainability Features

A noteworthy aspect is the rainwater collecting system, which addresses essential water management needs while promoting sustainability. This system collects and treats rainwater for drinking, reflecting a thoughtful approach to conservation. The project is designed with an eye toward environmental responsibility, showing an understanding of the local ecosystem and its resources.

Architectural Response to Terrain

The design pays close attention to the terrain by partially embedding the basement. This choice reduces the visual impact of the building and strengthens the connection between the structure and its landscape. This careful arrangement allows for living spaces that enjoy uninterrupted views and good ventilation, providing a pleasant atmosphere indoors.

Natural light plays an essential role in the home’s feel. Roof windows are included to enhance airflow and flood upper levels with light. These features contribute to a comfortable living space that feels open and inviting throughout the day.

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.
