Embodied Sustainability Through Engineered Timber and Natural Materials in a Visitor Center Design

Project in-detail

Constructed with engineered wood and integrated into the volcanic landscape, the visitor center seamlessly blends natural materials with sustainable design to enhance access to Iceland's geothermal features.
5 key facts about this project
01
Constructed with a focus on geothermal energy, the building features a water recirculation system for sustainability.
02
The use of jute burlap for insulation enhances both performance and tactile quality in the design.
03
A spiral staircase offers a unique ascent while providing panoramic views of the surrounding landscape.
04
Modular construction techniques allow for flexibility in design and adaptability to the site’s geological conditions.
05
The structure's footprint aligns with the natural fault line to minimize environmental impact and preserve the landscape.

The Grjótagjá Cave Tower is a thoughtfully designed architectural project located near Grjótagjá Lake in Iceland. It serves as a visitor center that offers access to a notable geothermal area within a unique geological landscape. The project aims to create an engaging user experience while integrating comfortably with the surrounding environment.

The architectural design emphasizes critical relationships between the built environment and natural surroundings. The structure’s modular form follows the geological contours of the land, promoting harmonious interaction and maintaining the visual rhythm of the landscape. This facility incorporates a variety of public and private spaces, allowing visitors to engage meaningfully with the site while enjoying views of the dramatic terrain.

Sustainability is at the forefront of the design. A range of materials has been selected for their functionality and aesthetic appeal. The use of engineered wood for the structural framework provides both strength and a natural appearance. Jute burlap is utilized for insulation and surface treatment, offering a textural quality that complements the natural environment. Corrugated metal sheets form the roof, ensuring durability against the harsh climate, while glass panels deliver ample natural light and unobstructed views of the exterior.

The layout of the Grjótagjá Cave Tower supports a variety of visitor functions, including a café, information area, and locker rooms. The provision of an observation tower serves not only as a lookout point but also adds a unique vertical element to the design. This staircase spirals upwards, providing an immersive ascent that culminates in panoramic views, thereby enhancing the visitor's experience of the landscape.

The project stands apart from many others in its meticulous integration with the site’s geology and ecology. Unlike typical visitor centers, the Grjótagjá Cave Tower embodies a deep respect for its surroundings. The design minimizes environmental impacts through thoughtful site selection and construction techniques, such as utilizing a flexible foundation that accommodates local geological conditions.

This project exemplifies contemporary architecture's potential to foster a connection with nature. The adaptability of the structure allows it to serve diverse functions while also emphasizing sustainability and respect for the environment. For further insights into the architectural plans, sections, designs, and ideas that underpin this project, readers are encouraged to explore the detailed presentation of the Grjótagjá Cave Tower.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
