Biogas-Powered Guesthouse with Modular Timber and Greenhouse Integration

Project in-detail

Harnessing biogas energy and modular timber construction, the facility integrates a greenhouse to enhance thermal performance while fostering community engagement in a guesthouse setting.
5 key facts about this project
01
Biogas system converts organic waste into usable energy on-site.
02
Modular guest room units allow flexible arrangements on the property.
03
Integrated greenhouse enhances indoor climate and supports local biodiversity.
04
Extensive use of timber emphasizes sustainability and connection to nature.
05
Lightweight aluminum construction reduces overall material load and increases adaptability.

## Overview
Located in the distinctive landscapes of Iceland, the Nature House is a carefully conceived architectural project that fosters interaction between visitors and the surrounding environment. The design integrates modern aesthetic principles with a strong emphasis on sustainability and energy efficiency, enabling guests to engage with the natural elements in a meaningful way while catering to practical requirements.

## Spatial Organization and Design Elements
The Nature House features a well-considered layout that comprises various zones tailored for specific functions. Guest accommodations include rooms designed to accommodate 2-4 occupants, with central core elements that allow tree growth, reinforcing ecological connections. Communal spaces, such as the dining area, serve as social hubs where guests experience Icelandic cuisine, while various private areas provide opportunities for quiet reflection.

Prominent design elements include a large greenhouse structure that optimizes natural light for the interior and enhances thermal efficiency through its innovative roof patterns. The use of locally sourced timber promotes sustainability and warmth, in contrast to the external climate. Extensive glazing establishes a visual and physical connection to the landscape, while lightweight aluminum in guest rooms ensures a modern, durable aesthetic that aligns with the project’s environmental ambitions.

## Sustainability and Resource Management
A range of sustainable practices underpins the Nature House, most notably a biogas digester that transforms organic waste into energy, contributing to a closed-loop system with minimal waste and carbon emissions. Rainwater harvesting systems further enhance the house’s sustainability by providing resources for landscape irrigation. Landscaping practices favor native plant species, reducing maintenance and promoting local biodiversity, thereby fostering a balanced relationship with the surrounding ecosystem.

This project exemplifies a thoughtful integration of architectural design with ecological responsibility, setting a benchmark for sustainable hospitality practices within remote environments.

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.
