Modular Living System Utilizes Wheat Straw and Recycled OSB for Sustainable Housing

Project in-detail

Constructed with recycled OSB and insulated with compacted wheat straw, the modular living system offers customizable housing solutions designed for energy efficiency and functional adaptability.
5 key facts about this project
01
Constructed with recycled pine wood OSB boards for reduced environmental impact.
02
Utilizes compacted wheat straw for superior thermal and acoustic insulation.
03
Modules can be configured independently to adapt to various spatial conditions.
04
Features an innovative interlocking rod system for flexible assembly.
05
Incorporates provisions for photovoltaic solar panels for energy autonomy.

The modular living system has been designed to meet various user needs through a flexible framework. It features five distinct modules, each dedicated to a specific living function. This setup enables individuals and families to customize their spaces according to their preferences and lifestyle. The design not only supports efficient use of space but also emphasizes sustainability within a modern living context.

Modular Configuration

The approach to modularity is practical and innovative, allowing the units to be installed together using interlocking rods or placed separately. This flexibility gives residents the freedom to adapt their homes based on available space or personal choices. It responds well to different environmental conditions, making it suitable for various settings.

Material Composition

Sustainability is a key feature in the construction of the modules. They are built with recycled pine wood OSB boards, which provide strength while minimizing environmental harm. Structural support comes from 3"x3" bars made of eucalyptus wood, secured to the primary wooden framework with iron plates. The walls are insulated with compacted wheat straw sheets, enhancing energy efficiency and providing sound and heat insulation.

Functional Distribution

The layout is designed for everyday living. The living/work/dining room integrates modular sofas and a folding table, allowing for a variety of uses. The kitchen includes large countertops that bring together storage, washing, cooking, and refrigeration into a single area. The bathroom unit features a shower and toilet, enclosed by a white opaque glass screen. In the bedroom, there is efficient use of space with built-in storage, a folding bed, and a desk that can be adapted as needed.

Sustainability Features

Provisions for sustainability enhance the design's practicality. There is potential for adding photovoltaic solar panels to support energy needs. A rainwater collection system is also part of the plan, allowing for the reuse of water in sanitary services and irrigation. These features reflect a commitment to environmental responsibility.

Large glass panels and metal profiles in the enclosure unit create a clear connection with the outside, promoting natural light and views toward the surrounding area. This design choice enriches the living experience by bringing nature into daily life.

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.
