Beltisdýr is an architectural design project located at the foot of a prominent mountain in Iceland. Its primary function is to serve as a multifunctional facility for visitors engaging in outdoor activities, particularly hiking. The structure effectively integrates with the surrounding landscape and enhances the outdoor experience by providing shelter and amenities within a natural setting. Designed to complement the rugged Icelandic terrain, Beltisdýr reflects a thoughtful approach to both architectural form and environmental context.

Material Selection and Structural Integrity

The building utilizes a range of materials that underscore its connection to the environment. Key materials include cross-laminated timber, concrete, glass, and locally sourced volcanic stone. Cross-laminated timber is employed for its strength, offering a sustainable alternative to traditional timber framing. Concrete is strategically used for its thermal properties and structural capabilities, ensuring longevity and insulation within the building. Expansive glass elements feature prominently in the facade, allowing visual connections between the interior and the landscape, while enhancing natural light throughout the space. This combination of materials not only addresses functional needs but also promotes energy efficiency.

Unique Architectural Features

One of the distinguishing characteristics of Beltisdýr is its unique walkable roof, designed as a continuation of the terrain. This architectural approach encourages visitors to interact with the landscape from an elevated perspective while providing additional recreational space. The building's geometric forms, inspired by local geological features, are intentionally crafted to create a dialogue between the construct and its surroundings. The interior layout incorporates flexible spaces designed for relaxation, social interaction, and service areas, fostering a communal atmosphere beneficial for various visitor groups.

Functionality and Visitor Experience

Beltisdýr features several functional zones, including a coffee shop, exhibition spaces, and restrooms, arranged to facilitate ease of movement and interaction. The design emphasizes spatial organization that caters to diverse activities while ensuring a seamless flow between different areas. Accessibility is a top priority, making the facility welcoming for all users. The use of warm wood finishes and thoughtful lighting enhances the interior environment, promoting a sense of comfort and connection to nature.

For more detailed insights into the architectural plans, sections, and design ideas of Beltisdýr, we invite you to explore the full project presentation. Understanding these architectural elements will provide a comprehensive view of the design intentions and functional planning behind this thoughtful structure.
