Rammed Earth Structure With ETFE Roofing Creating Communal Spaces in The Himalayas

Project in-detail

Constructed from rammed earth and topped with ETFE roofing, the facility integrates communal living spaces and sustainable practices in a mountainous environment.
5 key facts about this project
01
Integrates local rammed earth materials for enhanced insulation and sustainability.
02
Utilizes ETFE roofing to maximize natural light while minimizing structural weight.
03
Employs a geodesic design for optimized load distribution and earthquake resistance.
04
Incorporates a variable brick jig for on-site, tailored production of building materials.
05
Features a central hearth for communal warmth and social interaction within living spaces.

### Project Overview

Located in a mountainous region, this design draws inspiration from the spiritual principles associated with mandalas, reflecting a deep connection between built forms and cultural significance. The project incorporates locally sourced materials and energy-efficient strategies, enhancing sustainability and cultural resonance.

### Conceptual Framework

The design is informed by the symbolism of mandalas, characterized by their circular forms representing wholeness and interconnectedness. This geometric framework enhances communal living and interaction, aligned with the values of local Himalayan cultures. The architectural organization promotes spaces for social engagement and personal reflection, while integrating mathematical properties to illustrate natural patterns, thus fostering an educational environment alongside its primary functions.

### Materiality and Construction Techniques

The construction utilizes rammed earth bricks, chosen for their environmental benefits and thermal insulation, important for the mountainous climate. Complementing this are ETFE panels in the roof, which allow natural light ingress while supporting the structure's energy demands through solar integration. Wood, coconuts, and bamboo are incorporated to enhance interior warmth and reflect local craftsmanship.

The project employs innovative construction techniques, including geodesic tessellation for earthquake resilience and variable brick jigs for tailored production on-site. The use of color-coded bricks aids in construction efficiency while adding visual interest. These choices not only address functional needs but also ensure minimal environmental impact, promoting sustainable building practices.

### Functional Strategies

The design features a central hearth for heating common areas, effectively distributing warmth without smoke intrusion. Renewable energy sources, including wind turbines and solar panels, support the building's energy requirements. The layout of multi-use spaces allows for adaptable living arrangements, incorporating sleeping, cooking, and communal gathering areas to meet diverse user needs.

By intertwining resilience, sustainability, and cultural significance, the design stands as a functional and meaningful addition to its environment.

`
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.
