02
Incorporates geothermal heating principles for energy efficiency.

### Project Overview
Situated in the Icelandic landscape, "In the Center of the Hearth" explores the concept of retreat through a series of interconnected circular forms. The design prioritizes unity, shelter, and human interaction while accommodating the functional needs of a public facility aimed at visitors seeking rest and recreation. The integration of these spaces with the surrounding environment enhances the overall user experience.

### Spatial Arrangement and Functionality
The project's spatial configuration consists of multiple circular volumes, each designated for specific uses. The **Info Point** serves as the primary entry pavilion, offering technology and information while protecting visitors from the elements. The **Hearth**, positioned in the center, acts as a communal gathering area fostering social connectivity, equipped with amenities for refreshments. Additionally, a **Changing Room** is located at a lower elevation, designed for privacy and accessibility to outdoor areas. This arrangement facilitates smooth navigation between spaces, ensuring a harmonious coexistence of functions and engaging transitions that enhance visitor interactions.

### Materiality and Sustainability
Materials were selected for their aesthetic appeal, sustainability, and practical functionality, reflecting local construction practices while respecting the environment. **Corrugated metal cladding** provides structural stability and reflects the rugged landscape, while **polycarbonate panels** facilitate natural light infiltration. **Wood** is extensively used in interiors, adding warmth and insulation, and **concrete** is strategically incorporated for foundational elements necessary in the volcanic context. This selection represents a commitment to environmental sensitivity, aligning with Iceland's geothermal characteristics to promote energy efficiency and minimal ecological footprint.

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.
