03
Incorporates a closed-loop system for rainwater collection and organic waste processing.
04
Utilizes recycled steel for structural integrity while minimizing environmental impact.
05
Emphasizes thermal efficiency through ground embedding and adaptable elevations.

The Lake Myvatn Community House is located in the unique landscape of Iceland's Lake Myvatn region. It serves the local community and emphasizes principles of sustainability and environmental harmony. The design is centered around three important elements: landscape, water, and greenhouse, which work together to create a functional space that respects its surroundings.

Sustainable Design Principles

Central to the design is a commitment to sustainability. The building uses geothermal energy for both heating and hot water, reducing reliance on outside resources. This local energy source contributes to the overall goal of self-sufficiency. Rainwater collection and organic waste processing are also key features, forming a closed-loop system that enhances the building’s ecological impact.

Orientation and Energy Efficiency

Solar exposure is maximized through careful orientation. By facing south, all rooms benefit from natural light, fostering a pleasant interior environment. The greenhouse rooms, which surround the building, are designed to capture sunlight effectively from different directions throughout the day. This approach not only improves energy efficiency but also encourages local food production, reinforcing a connection between the community and its environment.

Materials and Local Context

The choice of materials reflects a deep connection to the landscape. Locally sourced basaltic stone and recycled steel establish a strong sense of place. These materials contribute to the building’s durability and thermal performance. The palette enhances the overall design while ensuring that the structure harmonizes with the surrounding environment, both visually and functionally.

Architectural Adaptability

Design elements include adaptable elevations that respond to Iceland's varied weather conditions. Panels in the greenhouse help to control light pollution while improving thermal efficiency. These thoughtful details ensure that the building remains comfortable and operational throughout the year, balancing practicality with a design that respects its ecological context.

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.
