Casa Gruta, situated in the Sisil neighborhood of Valladolid, Yucatan, is a remarkable architectural project by Salvador Román Hernández and Adela Mortera Villarreal. This home is conceived as a contemporary, livable sculpture, drawing inspiration from the distinctive geological formations of the Yucatan Peninsula—such as caves, grottoes, and natural wells. The design explores concepts of perception, scale, and materiality through a fusion of architectural design and visual art, evoking a sense of refuge reminiscent of caves.




This project invites reflection on the fleeting nature of time and the interplay between transience and eternity. It achieves this through the dynamic use of light and shadow, alongside the interaction between new architectural elements and existing natural structures. The minimalist material palette draws directly from the colors and textures of the surrounding environment. The exterior walls are coated in gray-green concrete, which shifts in saturation as the sun moves, creating an ever-changing atmosphere. Complementing this, natural cedar wood reflects the local vegetation and is accented with golden hardware that subtly hints at the mineral richness of the land.





The architectural concept is deeply rooted in the natural layout of wells and caves, where tunnels, arches, and open spaces direct the occupant’s sensory journey. The spatial experience alternates between openness and enclosure, offering varied sensations throughout the passage. A poplar tree stands at the entrance as a symbolic marker; in Yucatan, poplars traditionally signify the presence of underground water sources nearby. From here, visitors enter an outdoor foyer featuring a water element designed by Andrés Briceño, reflecting the Mayan purification rituals performed before entering natural wells.





The experience continues through a tunnel leading to the main corridor of the residence. The first room encountered offers a private terrace, outdoor shower, and a water feature. Moving forward, the tunnel opens into a communal area encompassing the living room, dining room, and kitchen, all situated beneath a hammered concrete dome. At the far end, a large cylindrical structure houses a staircase ascending to the rooftop leisure area, complete with an observation deck to take in the surrounding landscape.
On the upper floor, two additional bedrooms are located. One offers a private, contemplative terrace adorned with sculptures and lush vegetation. The master bedroom is the largest and features an indoor terrace at its far end. Here, a cylindrical water body shares space with an existing phoenix tree, creating a layered play of light and shadow that enhances the serene ambiance.




The Grota Residence serves as a sanctuary for introspection, offering a quiet retreat from the rapid pace of modern life. It is a space designed for contemplation and a deeper connection with the passage of time.
