Reykjavik-based architects Basalt Architects has designed a hotel and spa complex at Blue Lagoon, in Grindavík of Iceland.

The Blue Lagoon is situated within the UNESCO Global Geopark and comprises a series of pools containing geothermal seawater rich in minerals like silica and sulphur that are reputed to be good for treating skin conditions.

The 5-star hotel includes a health spa, restaurant with views over the Reykjanes Peninsula, and a luxury hotel with 62 rooms surrounded by the lagoon. In the northern end of the SPA, a new restaurant on the top floor allows views of the whole complex. Two wings are combined in the hotel lobby, which connects to the new SPA and the existing Blue Lagoon buildings. The surrounding environment is held in high regard and great emphasis is placed on the balance between buildings and nature.

The architects, in collaboration with Design Group Italia, use a natural palette in the interior spaces overlooking the rugged geography. The brutalist structure is revived on some materials such as grey lava, terrazzo, water and vibrant green moss.

"We wanted the lava, the moss, the water to be omnipresent, resulting in architecture that is woven in with the natural elements," the architects explained.
