Situated at the Fazenda Pedra Alta farm in Joanópolis, Brazil, the Altar Ninho Cabin by Natureza Urbana is an elevated, sustainable, and compact retreat designed for deep immersion in nature. Completed in July 2023, the 20-square-meter treehouse-style cabin is part of Altar's broader initiative to create decentralized hotels, offering a glamping experience that uses technology to promote sustainable hospitality. The cabin was constructed with a prefabricated metallic structure to minimize environmental impact and reduce on-site construction time. Elevated on metal pillars to a height of up to four meters, the structure's off-the-ground position reduces its footprint on the landscape, preserves the natural topography, and gives guests expansive views over the surrounding Atlantic Forest and the Joanópolis Reservoir. Inside, the living, kitchen, and bedroom spaces are integrated into a single, light-filled environment, with a strategically placed large opening next to the queen-size bunk bed offering direct and immersive views of the reservoir. The bathroom is illuminated by a zenithal opening, providing views of the sky and treetops from within. The interior and exterior spaces are connected by a generous natural wood deck, where guests can enjoy a leisurely area with furniture, a shower, a barbecue grill, and a space for a bonfire. The project's design prioritizes a rational and sophisticated geometry, with a simple yet elegant aesthetic that seamlessly integrates with the forest environment. A 2022 collaboration with Tok&Stok, which included a line of furniture and decorative items designed by Natureza Urbana, informed the cabin's sustainable ethos.
