The ÖL-SPA project located in the Skútustaðagígar region of Iceland is an architectural design that effectively integrates wellness amenities with the natural landscape. This facility emphasizes relaxation and social interaction while enhancing the aesthetic value of the surrounding terrain. The design reflects a focus on cohesion between human activities and nature, making it a model for contemporary spa facilities.

Design Concept and Structure
The architectural form is characterized by a cylindrical shape, a direct reference to the surrounding volcanic craters. The use of sloped roofs and extensive glass facades allows natural light to permeate the interior while providing unobstructed views of the picturesque environment. The roofing system is designed to manage snow loads effectively, which is critical in Iceland's harsh winter conditions. The structure is enveloped in blackened timber, a material choice that resonates with the volcanic landscape, while mirrored glass enhances visibility and interacts naturally with the scenery.

Functionality and Interior Layout
ÖL-SPA is designed to serve multiple functions: it includes a spa with temperature-regulated indoor and outdoor pools sourced from geothermal hot springs, private treatment rooms, and communal spaces that foster social interaction. A central brewery and beer hall encourage gathering, emphasizing the community aspect of the facility. The layout distinguishes public areas from private spaces, ensuring guests can enjoy relaxation with a sense of solitude.

Unique Design Approaches
One of the key aspects that set the ÖL-SPA apart is its commitment to sustainability. The architectural design incorporates locally sourced materials, ensuring minimal environmental impact. The building's relationship with the landscape is foundational; the structure's rounded form and materials echo the rolling shapes of the nearby terrain. The infinity pool located on the roof not only provides unique aesthetic qualities but also merges the leisure experience with the stunning natural backdrop.

Architectural Details and Materiality
The selection of materials significantly contributes to the overall design ethos. Ethically sourced wood forms the primary structural framework, while the facades utilize large expanses of mirrored glass that reflect the environment, enhancing the immersive experience of the natural surroundings. Corrugated metal roofing ensures durability, addressing the challenges posed by Iceland's climate. Volcanic rock is incorporated into the landscaping, reinforcing the connection to the locale.

To explore the nuances of the ÖL-SPA project, including architectural plans and detailed designs, a comprehensive review of its presentation is recommended. The architectural sections showcase the thoughtful interplay of form, function, and landscape integration that characterizes this unique facility.
