Welington Cruz
Interior Designer
"The decoration of Astrum Vallis articulates Portuguese heritage (stone, wood), memory of the enslaved (rammed earth), and high-standard Smart Home technology that operates discreetly. The project favors authentic textures, sensory comfort, and a design that frames the landscape. Result: tradition and future in balance, with a sophisticated experience that values local history and contemplation of nature."
Alexandre Loureiro
Architect
"Astrum Vallis offers accommodation integrated with the land: the dome rests on the mountain with minimal intervention, preserving nature and views. The geodesic structure ensures thermal comfort and a spacious, welcoming environment. Low-impact materials guarantee sophistication with environmental responsibility, inviting guests to reconnect with the landscape."
Renan Ivo
Landscape Designer
"At Astrum Vallis, we treat sanitation and landscaping as essential parts of the experience. The ecological system, combining Bioete, stone filter, and banana circle, returns treated water to the environment safely and with environmental sense. In landscaping, we prioritize native species to create an authentic garden, resilient and integrated into the local biome. The result is a space where technique, beauty, and respect for nature complement each other."
