Porous Skin Structure Enhanced by Local Soil and 3D Printing as a Compact Living Space

Project in-detail

Utilizing local soil and advanced 3D printing techniques, this compact living space features a porous skin that optimizes ventilation and light, creating an integrated environment for modern living.
5 key facts about this project
01
Utilizes local soil mixed with additives for its 3D printed envelope.
02
Incorporates parametric modeling to create adaptable geometric forms.
03
Features a central tree that enhances airflow and visual connection.
04
Designed for optimal natural light and ventilation throughout the year.
05
Eliminates traditional walls for a flexible open living environment.

The "Looking Forward" design is located in the scenic regions of New Zealand. It serves as a compact living space for two people, showcasing a thoughtful blend of different architectural styles. The design plays with both rigid geometric forms and a more fluid, organic shape that comes from 3D printing. This combination aims to create a comfortable environment, emphasizing natural light and effective ventilation.

Design Concept

In this design, parametric modeling shapes the envelope that wraps around the living unit. By adjusting various points in the model, the shape of the building can change, allowing for multiple configurations that are both functional and visually interesting. This flexibility offers a range of options that meet the needs of the environment and the inhabitants.

Environmental Performance

Environmental considerations are a core part of the design. The outer skin is designed to enhance airflow and maximize daylight. Its porous structure allows sunlight to enter during winter while providing shade in the summer. This feature reduces the need for heating and cooling, which contributes to an energy-efficient living space that adapts to seasonal changes.

Construction Techniques

The construction approach for this design involves digital fabrication methods, particularly 3D printing. Using a mixture of local soil and specific additives, the outer shell of the building is produced on-site. This process not only reduces transportation costs but also promotes sustainability by utilizing materials that are readily available, maintaining precision throughout construction.

Aesthetic Considerations

Inside, the cabin offers an open layout, allowing for various living activities without traditional walls. This openness creates a sense of spaciousness and flexibility. The furniture is placed strategically to define different areas within the space. A central tree is featured in the design, surrounded by a glass cylinder, serving both as a visual focal point and a means of improving airflow.

Large windows let in plenty of natural light, creating a warm atmosphere inside. The play of light and shadow on the outer skin adds a dynamic quality to the living environment. Views of the surrounding landscape are unobstructed, reinforcing the connection between the home and its natural setting.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
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.
