Laugarás Lagoon: Iceland's Geothermal Spa with a Grass-Covered Roof
T.ark Architects' innovative Laugarás Lagoon project reimagines the spa experience, drawing profound inspiration from Iceland's unique landscape. Instead of mimicking the country's dramatic glaciers or black sands, the design thoughtfully integrates with the gentler, rolling meadows and ancient, hand-carved caverns of southern Iceland. This approach results in a structure that feels less like a building and more like an extension of the natural environment, creating a truly immersive and tranquil retreat.
Laugarás Lagoon: A New Icelandic Landmark Blending Nature and Heritage
In the serene landscape of Laugarás, approximately 90 minutes east of Iceland's vibrant capital, Reykjavik, a groundbreaking architectural marvel has emerged. T.ark Architects, an acclaimed Icelandic studio, has recently unveiled the Laugarás Lagoon, a magnificent geothermal spa spanning 3,000 square meters. This two-story wellness sanctuary is ingeniously crowned with a living, grass-covered roof featuring expansive parabolic archways, paying homage to the region's ancient subterranean dwellings.
The spa's design ethos consciously departs from typical Icelandic rugged aesthetics, instead embracing the tranquil beauty of its southern pastures and woodlands. Halldór Eiríksson, a partner at T.ark Architects, revealed that the core concept revolved around the "farm mound" penetrated by "cave openings," transforming the landscape into both the spatial and architectural language of the lagoon. The structure's glue-laminated timber roof, affectionately termed a "grass tent," is meticulously crafted to integrate with its surroundings, offering framed views of the natural waterscapes through its signature arches.
Upon entering the Laugarás Lagoon from its northern side, visitors are greeted by a vast, inviting reception area that seamlessly transitions into a restaurant space. Here, the architectural design prioritizes an open, airy feel; partition walls intentionally fall short of the timber-lined ceilings, evoking the expansive atmosphere of a "covered plaza" rather than a conventional interior. The restaurant's aesthetic, a collaborative effort with interior designer Anthony Bacigalupo, features pink-hued travertine and clay-plastered walls crafted from local red gravel, immersing guests in the authentic textures and colors of Iceland.
The spa's thoughtful layout continues with fully glazed walls, discreetly set back from the building's sloping arches. These allow for breathtaking views from the changing rooms across the upper geothermal pool, which is strategically positioned to capture vistas of a nearby river, bridge, and distant mountains. In contrast, the lower pool offers a more intimate and secluded experience, framed by surrounding trees and rugged stone walls. Both pools are equipped with convenient swim-up bars and a cold-water plunge. Additionally, two distinct dry saunas are housed within minimalist cubic volumes on the eastern side of the complex, providing tranquil spaces for relaxation. Beneath the main structure, a comprehensive basement level accommodates the spa's vital plant area, along with essential service and staff zones.
Eiríksson elaborated on the interior dynamics: "Black wood-clad boxes are tucked under the roof from the sides, for functions like changing rooms, kitchen and lagoon bar." He highlighted the "dialogue of overlapping spaces," where these functional boxes define central areas while the enveloping grass tent creates integrated corridors. This interplay of protection and exposure guides visitors on a journey of discovery through various coves, saunas, and the immersive forest pool. The materials selected for the project underscore a commitment to local sourcing, with all timber for both interior and exterior applications, as well as the grassy turf for the roof, harvested from nearby woodlands. The spa experience is further enriched by bespoke textile art from Sigmundur FP and a unique range of site-specific scents, distilled from local vegetation by olfactory art lab Nordic Angan for the lagoon's soaps, ensuring a truly multi-sensory and localized immersion.
The Laugarás Lagoon project stands as a testament to how architectural innovation can profoundly connect with and elevate its natural and historical context. It demonstrates a harmonious blend of functionality, aesthetic beauty, and respect for local heritage, offering a spa experience that is deeply rooted in the Icelandic spirit. This project not only provides a serene escape but also serves as an inspiring example of sustainable design, showing that contemporary structures can honor and enhance the landscapes they inhabit without compromising modern comforts. It encourages a deeper appreciation for the subtle beauties of nature and the rich history embedded in the land, proving that the most impactful designs are often those that listen closely to their surroundings.
