## Overview

The Modular Mountain project, located in the Himalayan region, is conceived as a sustainable accommodation designed to provide trekkers with comfortable amenities while minimizing ecological impact. The architectural intent focuses on integrating the structures with the natural landscape, utilizing modular components to maintain adaptability in construction and operation.

## Spatial Strategy

The design organizes the retreat into a two-story configuration built from seven modular units. The ground floor features a common area for social interaction, kitchen and dining zones to promote communal engagement, and dedicated spaces for relaxation. On the upper floor, sleeping arrangements accommodate both communal and private needs, with individual alcoves designed to enhance privacy. A service module supports essential functions, including water storage and filtration systems integrated with bath facilities.

## Materiality and Sustainability

Attention to material selection plays a critical role in achieving sustainability objectives. Galvanized steel is utilized for roofing and facade elements, ensuring durability and low maintenance. Wooden panels introduce warmth and texture that harmonize with the surroundings, while copper detailing acknowledges local architectural traditions. Large glass windows optimize natural light and provide panoramic views of the mountainous landscape. The design also incorporates systems for rainwater harvesting and solar energy generation, addressing both water management and energy efficiency throughout the year.

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.
