Sebastián Sas and Bjarke Ingels rarely share a brief, so the fact that their Oneness studio took on the transformation of a 1970s Ibizan beach resort — the old BG Portinatx Beach Club Hotel on the island's quieter northern coast — signals how unusual a project Nômade Temple Ibiza actually is. Oneness preserved the original building's colonnaded arcades, that run of rounded arches in warm sandstone that photographs like a Moorish palace dropped into pine-covered hills, then worked outward from that inherited geometry to create something far more layered than a renovation. The massing steps upward in terraced volumes, the whole complex clad in piedra blanca and finished in ochre-tinted render that shifts tone through the day as Mediterranean light moves across its surfaces. Inside, the 182 rooms show sabina wood headboards, tadelakt-adjacent plaster walls in amber and terracotta, woven flat-weave rugs in saffron and rust, and pendant lights with a handblown quality that places them closer to the craft markets of Marrakech than to the design showrooms of Barcelona. Freestanding soaking tubs sit on timber-decked terraces framed by those same trilobate arch openings, the views through them of olive trees and white-walled bungalows across the valley. Beyond the rooms, an 810 square metre spa, a recording studio, and a performance space conceived around M.C. Escher's impossible geometries give the property a cultural ambition that most wellness hotels in the Balearics don't attempt.
