Basalt Formation Embraced by a Membrane in a Community-Focused Guesthouse

Project in-detail

Embracing the region's columnar basalt formations and utilizing a thermal-regulating membrane, the guesthouse offers a unique communal experience in the harsh Icelandic climate.
5 key facts about this project
01
Utilizes local columnar basalt formations as a prominent structural element.
02
Incorporates a thermal-regulating membrane for energy efficiency.
03
Features communal living spaces designed to encourage social interaction.
04
Integrates multiple renewable energy sources for sustainable operation.
05
Addresses the harsh Icelandic climate with site-specific design strategies.

The design is located in Iceland, which is known for its extreme weather and dramatic landscape. It aims to create an experience that connects people with this unique environment. The concept focuses on combining local resources and architecture, allowing the building to fit naturally within its surroundings. This connection between the built form and the landscape shapes the essence of the design.

Site Integration

The design takes inspiration from the natural features of the landscape, particularly the columnar joint basalt formations found in the area. By using these elements, the building connects deeply with its site, reinforcing a continuity with the environment. The structure emerges from the ground, making it feel as if it is part of the landscape rather than just placed on it.

Thermal Regulation

Iceland’s climate presents challenges, with a mix of coastal and tundra weather. To address this, the design includes membranes that help regulate temperature efficiently. These membranes capture sunlight and store heat, ensuring a comfortable interior throughout the year. By focusing on energy performance, the design seeks to provide warmth and comfort while minimizing energy use.

Sustainability and Resource Management

The commitment to sustainability is integral to the design. It incorporates various renewable energy sources, such as geothermal, hydropower, solar, and biomass energy. This energy cycle reduces the building's impact on the environment and promotes responsible resource management. By utilizing local energy sources, the design aligns with the principles of sustainability while contributing to the surrounding ecosystem.

Community Engagement

The layout emphasizes social interaction among guests. Spaces such as a reception area, guest rooms, and an open-air lounge encourage people to gather and connect. Additional amenities like outdoor hot tubs and shared kitchens provide opportunities for communal living. These features create a welcoming environment that allows individuals to engage with the local climate and enjoy their surroundings.

The building design captures the essence of the Icelandic landscape, allowing inhabitants to experience the unique environment while enjoying comfort and community. Each aspect of the design reflects a thoughtful approach to living in harmony with nature.
