Charred Wooden Cladding and Cross-Laminated Timber Panels Embrace Geothermal Harmony in Icelandic Lodging

Project in-detail

Utilizing charred wooden cladding and cross-laminated timber panels, the design integrates geothermal energy to provide a sustainable guest house that harmonizes with the Icelandic landscape.
5 key facts about this project
01
The guest house employs Shou-Sugi-Ban technique for enhanced wood durability and fire resistance.
02
Rainwater harvesting systems are integrated for efficient water management and resource conservation.
03
The design prioritizes panoramic views of the Northern Lights from each guest room.
04
Turf roofing not only provides insulation but also blends the structure into the natural landscape.
05
A communal kitchen encourages social interaction among guests while fostering a sense of community.

### Overview

The guest house project "IN RETURN" is situated in the Myvatn area of Iceland, renowned for its striking natural beauty, geothermal systems, and the Aurora Borealis. The design emphasizes a connection between the built environment and the unique landscape, merging elements of traditional Icelandic architecture with modern sustainable practices. Key objectives include minimizing environmental impact and utilizing local materials, enhancing guests' experiences through immersion in the natural setting.

### Design Concept and Layout

The design prioritizes a layout of compact individual guest rooms surrounding a central communal building, with pathways designed to foster interaction while maintaining ecological integrity. The buildings' arrangement is strategically oriented to maximize views of the Auroras and adapt to the land's contours, promoting a cohesive relationship with the surrounding environment. Each guest room accommodates two to four individuals and is equipped with essential amenities while allowing access to natural light through well-placed windows.

### Materiality and Sustainability

The selection of materials is tailored to address the local climate and sustainability goals. Cross-Laminated Timber (CLT) serves as the primary structural element, offering strength and aesthetic compatibility with the natural landscape. Shou-Sugi-Ban wood cladding provides durability, while insulating wood fiber sheeting enhances thermal efficiency. Large, triple-glazed windows are utilized for optimal illumination and landscape connectivity. A turf roof adheres to traditional Icelandic methods, providing insulation and further blending the building with its environment. Renewable energy systems, including geothermal heating and solar panels, are integral to the project's reduced ecological footprint, ensuring a sustainable operation in alignment with local climatic conditions.
