Renatta Chain

Renatta Chain is a Mexican designer and co-founder of Chain + Siman, an architecture and interior design practice based in Mexico City. She began her professional career in Miami, working on residential projects before establishing her own firm, RCH, in 2003. Her early interest in design was shaped by her grandmother, the Mexican sculptor Charlotte Yazbek, whose work encouraged an appreciation for line, colour, and form, and the connections between visual art and the creation of spaces.

In 2016, Chain joined forces with Lina Siman to establish Chain + Siman, expanding her practice across residential, hospitality, commercial, and corporate projects. Their approach centres on clean lines, natural materials, and the relationship between light, texture, and space. Each project responds to the particular needs of its occupants and the characteristics of its setting, bringing functional planning together with attention to atmosphere, proportion, and detail.

Casa Rancho Avándaro, a retreat in Valle de Bravo, demonstrates this connection between architecture and place. Drawing on the organisation of Mexican haciendas, the residence combines three principal volumes with patios, locally sourced materials, and pitched roofs supported by timber beams. Exposed stone, wood, and ironwork establish a material continuity between the building and its interiors. The project received recognition from the International Design Awards and DNA Paris Design Awards for its contemporary interpretation of a familiar architectural tradition.

Her work with Siman also explores how custom furniture, finishes, and lighting shape domestic experience. At Ochre House in Mexico City, oak floors and ceilings, bespoke furnishings, and warm tones respond to the changing daylight. A staircase surrounding a tree connects the home’s two levels, while quarry stone introduces a contrasting texture. In Península Apartment, black walnut and grey marble recur across architectural finishes and designed furniture, with lighting used to articulate the spaces and reveal their material qualities.

Hospitality projects extend this sensitivity to shared environments. At La Acuarima in Valle de Bravo, a circular restaurant sits on a platform above a lake, opening the dining space towards the surrounding landscape. Wood, brick, and a perimeter terrace establish a close relationship between interior and exterior. The project received a LIV Hospitality Design Award, while Ochre House earned Gold in Residential Interior Design at the International Design Awards, recognising work developed jointly by Chain and Siman.
