Folding Shell Structure in Fibre Reinforced Concrete for Efficient Micro Living

Project in-detail

The innovative folding shell structure crafted from fibre reinforced concrete redefines compact living by maximizing spatial efficiency and environmental integration in a modern microhome.
5 key facts about this project
01
Unique folding shell structure allows for adaptable interior configurations.
02
Constructed from fibre reinforced concrete for enhanced durability and efficiency.
03
Elevations designed for optimal natural light and airflow throughout the space.
04
Compact footprint supports sustainable living in a limited residential area.
05
Entrance dimension promotes accessibility while connecting interior and exterior seamlessly.

The microhome project is a contemporary design located in Sweden, intended to meet modern housing needs through a small and functional living space. The design emphasizes efficiency and adaptability, carefully integrating with the local environment. By maximizing natural light and airflow, the microhome creates a comfortable and livable atmosphere while showcasing a modern aesthetic.

Design Concept

The layout consists of three distinct levels: the roof level at +3.400, the first floor level at +2.100, and the ground level at +0.000. This vertical arrangement organizes interior spaces effectively, allowing occupants to connect with the landscape, enhancing both views and daylight access. The elevations, particularly the North and West facades, highlight visual symmetry, contributing to a consistent exterior appearance.

Structural Innovation

A key feature is the folding shell structure, which measures 1.88 m, 3.61 m, 0.46 m, and 2.30 m. This innovative shape provides flexibility for different spatial arrangements, addressing various living needs. The folding shell design not only adds a unique character but also suggests improved energy efficiency, as its form may help with thermal regulation and environmental performance.

Material Application

Fibre reinforced concrete is chosen for its versatility and lightweight nature. This material allows for thinner sections without compromising strength. By using custom molds in the casting process, the project achieves a specific architectural form that aligns with the vision of modern residential design.

Entrance Design

The entrance, which measures 1.50 m, serves as a welcoming point between the outside and the home’s interior. This thoughtful design enhances accessibility while reinforcing the connection with the surrounding environment. Such attention to detail shows a commitment to creating a user-friendly living space that focuses on comfort and practicality.

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.
