Conical Roof Structure Featuring Laminated Timber and Recycled Concrete at Volcano Base

Project in-detail

With a conical roof crafted from laminated timber and walls made of recycled concrete incorporating volcanic ash, the facility serves as both a coffee shop and road trip centre, enhancing visitor engagement at the foot of Hverfjall volcano.
5 key facts about this project

Skylights allow natural light to permeate interior spaces during the day.

Up The Mountain Path is located at the base of the Hverfjall volcano in Iceland. The project includes a coffee shop with exhibition spaces and a road trip centre that provide essential services for visitors exploring the area. The overall design focuses on integrating the architecture with its natural surroundings, allowing guests to connect with the landscape and learn about its geological significance.

Architecture Concept
The design establishes a close relationship between the built environment and the natural landscape. The coffee shop serves as a place for visitors to enjoy refreshments and provides educational information about Hverfjall and the Mývatn Nature Reserve. The road trip centre meets the practical needs of travelers, offering facilities such as showers and laundry. This combination of services encourages exploration and enhances the visitor experience.

Design Features
A distinct pathway system guides guests from the parking area to both structures and up the volcano. The paths are designed to reveal scenic views and encourage movement through the site. Architectural elements include a conical roof with a skylight, which allows natural light to enter the interior spaces. This feature creates a visual link between the building and the surrounding environment, reflecting shapes found in the Icelandic landscape.

Materials and Sustainability
The main structure uses glued laminated timber, known for its strength and lightweight qualities. A living roof grows into the surrounding landscape, while walls and floors are made of recycled concrete mixed with local volcanic ash. Black wood is used in various interior elements, such as furniture and multifunctional steps, promoting a sense of unity between the building and nature.

Lighting Strategy
Lighting design is carefully considered to enhance the visitor experience. Daylight enters the interiors through skylights and corridors, creating a bright atmosphere during the day. At night, exterior lights are kept to a minimum to reduce light pollution and preserve the night sky. This balance of natural light and subtle artificial lighting draws attention to both the beauty of the landscape and the architectural details.
