Elqui Domos, Valle de Elqui, Chile

Sited within Chile's Andes-sheltered Valle de Elqui, this eco-resort has had a makeover by Santiago-based architect Rodrigo Duque Motta of RDM Arquitectura, who not only redesigned the existing seven geodesic-dome rooms and common areas, but also created an additional four cabins. The new cube-like structures are fashioned entirely from local wood. Slightly elevated, they've been positioned to make the most of the endless scenery; each comprises its own roof deck and a glass ceiling above the bed - perfect for a spot of stargazing.
