green pigmented concrete facades sculpt casa gruta in yucatán, mexico
the house takes inspiration from yucatán’s caves, grottoes, and cenotes, integrating their organic qualities into the design.
Geological Formations Inspire Casa gruta’s Architecture
Located in the Sisal neighborhood of Valladolid, Yucatán, Casa Gruta is an architectural project designed by architects Salvador Román Hernández and Adela Mortera Villarreal. The design explores perception, scale, and materiality through an architectural and sculptural approach that evokes the feeling of a shelter, reminiscent of a cave. The residential project invites reflection on the passage of time and the relationship between the ephemeral and the eternal through the interplay of light and shadow and the dialogue between new and pre-existing structures.
Conceived as a contemporary habitable sculpture, the house draws inspiration from the geological formations characteristic of the Yucatán Peninsula, such as caves, grottoes, and cenotes. Its materiality is rooted in the colors and textures found in these natural environments. The facades are made of greenish-gray pigmented concrete, which shifts in saturation throughout the day as sunlight changes, creating a dynamic atmosphere. In contrast, natural cedar wood elements reference the local vegetation, while golden metal accents evoke the minerals present in the earth.

Light, Shadow, and Nature inform Casa gruta’s Spatial design
The house’s design by architects Salvador Román Hernández and Adela Mortera Villarreal takes cues from cenotes and caves, where tunnels, vaults, and open spaces guide the sensory experience of the user. Spaces expand and contract, offering varied sensations throughout the journey. The entrance is marked by an álamo tree, which in Yucatán traditionally indicates the presence of underground formations. This leads to an open-air vestibule featuring a body of water, an installation by Andrés Briceño, inspired by Maya rituals performed before entering a cenote.
A tunnel extends from this vestibule to the main distribution area of the house. The first space encountered is a bedroom with a private patio, an outdoor shower, and a water feature. As the journey continues, the tunnel opens into a communal area that includes the living room, dining area, and kitchen, all beneath a hammered concrete vaulted ceiling. This space culminates in a large cylindrical volume housing a staircase that leads to the rooftop, an open recreational space with a viewing platform for appreciating the surrounding landscape. On the ground floor, the house includes two additional bedrooms. One, more secluded, features a contemplative patio with sculptures and vegetation. The main bedroom, the largest, opens onto an interior patio with a cylindrical water feature, alongside a pre-existing tree that casts intricate patterns of light and shadow. Casa Gruta serves as a retreat that encourages introspection and reflection on the fast pace of contemporary life, offering a space for contemplation and a deeper connection with time.
