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.

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.
