Cork-Insulated Microhome With Fir Structure in the Italian Alps

Project in-detail

Constructed with fir and rockwool insulation, this microhome in the Italian Alps offers a sustainable living solution tailored for remote work and eco-tourism while seamlessly integrating into its alpine landscape.
5 key facts about this project
01
Constructed at varying altitudes for specific user needs.
02
Incorporates local stones for foundational support.
03
Utilizes cork insulation for enhanced waterproofing.
04
Features a modular design facilitating on-site assembly.
05
Equipped with systems for rainwater collection and gray water recycling.

The architectural design in Rabbi Valley, located in the Italian Alps, provides an exploration of modern alpine living. Set at different elevations, this microhome development aims to support sustainable tourism and the needs of remote workers. The design includes three distinct prototypes, each created to serve specific users while respecting the unique characteristics of the alpine environment.

Design Concept
The microhome consists of two main volumes: one for living and another for sleeping. This separation allows for flexible use and accommodates both short-term visitors and long-term residents. The larger sleeping area has a single-pitch roof that provides privacy. In contrast, the smaller living area features a double-pitch roof, which enhances the views of the surrounding mountains and improves the overall experience for users.

Modularity and Structure
To address challenges associated with high-altitude construction, the design uses a lightweight modular structure that is easy to assemble on-site. Panels measuring 1 meter by 2.5 meters streamline the building process, making it suitable for the rugged conditions of the alpine landscape. This modular approach also allows for adjustments to the layout as needs change over time, offering flexibility in design.

Materiality
Sustainability is a key consideration in the choice of materials. Structural elements are made from fir tree, valued for its energy efficiency and eco-friendly qualities. Insulation is provided by rockwool, and an additional layer of cork is included for added waterproofing. The use of local stones for the foundation reflects the regional context, minimizing transportation issues and reinforcing a connection to the surrounding nature.

Sustainability Features
Energy efficiency plays an important role in the design. Solar panels on the building allow for energy independence, promoting responsible consumption. The project also incorporates systems for collecting rainwater and recycling gray water, further supporting its self-sufficient design.

The microhome project aims to meet the needs of contemporary alpine living with a focus on functionality and environmental care. The thoughtful relationship between the two volumes and the careful selection of materials highlight a bond with the natural surroundings. Such design emphasizes a practical approach to living in harmony with the landscape.

Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
