Casa Toquilla weaves a safe haven in the vernacular architecture of Ecuador
The article explores Casa Toquilla, a project by Ecuador-based Rama Estudio, which aims to revive vernacular architecture and local construction techniques in the aftermath of a devastating 2016 earthquake. The initiative addresses the displacement of 80 families from the island of Portete in the Province of Esmeralda, who, upon moving to the mainland, lost their connection to traditional building methods, local materials like bamboo, wood, toquilla straw, and kade, and a sense of ownership over their homes. These endemic materials had been stigmatized as low-quality alternatives to modern materials such as zinc plates, blocks, and concrete.
Rama Estudio collaborated with the Portete community to develop Casa Toquilla, emphasizing responsible, respectful, and responsive architectural intervention. The project involved an extensive process of understanding site safety concerns, evaluating traditional construction techniques, and utilizing locally available materials. Through community discussions, experiments, and active participation, the architects and residents co-created three prototype houses: Casa Toquilla L, Casa Toquilla M, and Casa Toquilla S. These designs are rooted in sustainable design principles and feature bamboo construction.
The housing trilogy comprises prototypes designed to cater to different family sizes, economic capacities, and ease of execution. Casa Toquilla L, the largest at 80 sqm, is a single-floor residence accommodating up to eight people, designed with elderly users and ease of movement in mind. It includes two bedrooms and a common area. Its thermal performance is enhanced by a floor grid for cold air recirculation and pambil screens with mosquito nets. Casa Toquilla M, covering 70 sqm, is a two-story structure for eight members, featuring ample meeting spaces and built on a raised deck to ensure material durability. Casa Toquilla S, the smallest at 60 sqm, optimizes space with an open-plan layout and omits the first-floor balcony present in Casa Toquilla M.
A key aspect of Casa Toquilla's uniqueness lies in the integration of technical details into the spatial development. The toquilla straw weave is incorporated directly into the residential architecture, and the roof profile and attic spaces create functional areas on the upper floors. Pambil screens, highly resistant to weather and humidity, enclose the elevations and form the facade. These elements also facilitate cross-ventilation, creating open and comfortable living spaces. The project also included practical training for the local community in bamboo construction and toquilla straw weaving, fostering local labor engagement and knowledge transfer. The houses were treated with various preservation and curing methodologies to assess their durability in a humid and saline coastal environment, with the goal of creating accessible and efficient construction techniques. The initiative has led to the replication of its methodology in three additional homes in the area, demonstrating its potential for wider application and impact. The project serves as an example of humanitarian architecture, showcasing how responsible design can help a displaced community reconnect with its cultural heritage and build a sustainable future.
