### Overview

Situated in the distinct landscapes of Iceland, the design of House XYZ integrates innovative architecture with environmental considerations and sustainable practices. The structure operates as both a residential retreat and an artistic engagement with its surroundings, emphasizing a balance between human habitation and the natural environment. Through its strategic architectural form, the project invites users to experience the dynamic Icelandic climate while respecting the beauty of the landscape.

### Spatial Organization

The internal arrangement of House XYZ accommodates various visitor experiences, catering to both transient guests and those seeking longer stays. It comprises eight compartments, half of which are dedicated to private living quarters designed for comfort and solitude. Communal spaces promote interaction among occupants, facilitating a shared appreciation of the environment while optimizing natural light and flow throughout the interior. This duality of private and communal arrangements reflects the diverse needs of its users.

### Material and Technological Integration

The material selection and construction techniques employed in House XYZ prioritize sustainability and environmental harmony. Rammed earth walls are crafted from local soil, providing thermal mass and significant insulation. Concrete elements, including floors and roofs, are cast on-site, reducing waste and supporting structural efficiency. A repurposing strategy for plywood, initially used as formwork and subsequently transformed into furniture, underscores a commitment to minimizing environmental impact. Technologically, the design features a vertical-axis wind turbine that generates energy, alongside natural heating and cooling systems including strategically placed chimneys and fireplaces, which enhance the design's functionality in responding to the Icelandic climate.

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.
