The DNA: It would be impossible for The Retreat at Blue Lagoon‘s interiors to surpass the beauty of the surrounding landscape, so instead they pay homage to it: carpets are grey-blue and moss green; slabs of solidified lava have been broken into rough-hewn bricks to create a signature fireplace or levelled to form a statement bar; decades-old Icelandic ceramics decorate the lobby. It all feels suitably Icelandic, though there are subtle Italian influences too. Furniture comprises pieces by B&B Italia, and Marche-based iGuzzini collaborated with the property to develop “human-centric lighting”. Light installations and fixtures include gently pulsating sun- and moon-like orbs that glow from the ceilings at certain times of day and night. Guests have direct access to a private part of the lagoon.
