Casa Cosecha de Lluvia is located in a community of landscape-driven homes called Reserva el Penon, set across 450 acres.
Sitting as part of a larger community of landscape-driven homes referred to as Reserva el Penon, there is a compounding effect from the collective behavioural effort of using and reusing water and other energy sources. “We saw the project as a way to test out a new way of thinking, which we could then hopefully apply to future projects as well,” architect Robert Hutchison says.
Each home in the reserve is required to incorporate rain harvesting, most coming from the individual home’s rainwater harvesting system and a small portion coming from the reserve’s reservoirs. “We wanted to see if we could harvest 100 per cent of our water from our individual site rather than depend on external sources,” Robert says. “The result is a 100-per-cent-water-autonomous project that collects and treats all the rainwater, greywater, and black water on site.”
Nature-inspired, hard-wearing materials like steel and timber ensure the home’s permanence in the landscape.
In the kitchen, an island bench made of stone and stainless steel contrasts with the surrounding timber tones.
Opting to showcase the mechanisms supporting the home, the table is flipped, and the curtain is drawn on the wakefulness of impact. “Casa Cosecha has a basement that was built to showcase the water systems in a very didactic way,” JSa Arquitectura director Javier Sanchez says. “The result is to inspire people to understand that they also need to include the systems, not only bedrooms and bathrooms but all the systems that make a house work in today’s compromised environment,” Javier adds.
As the harvesting and reuse potential of the natural elements within design is becoming better understood, its integration is becoming an endemic and core part of practice. A counter to the climatic conditions, Casa Cosecha de Lluvia comprises a series of smaller structures that incorporate holistic principles, surrounded by bio-agricultural gardens and an orchard that build on the retreat’s self-sufficiency. Connection with the environment is constant, as the main residence looks out to the landscape in all four directions, while all three structures have vegetated roofs. The bathhouse, comprising a hot bath, sauna, steam shower and washroom, with a cold plunge pool in the centre, is oriented to the sky above and water below.
All three structures deeply contrast with the tones of the landscape, yet still form a natural part of it.
The stand-alone bathhouse sits a small distance away from the main house and supports four bathing activities: hot bath, sauna, steam shower and washroom. The spaces encircle a cold plunge pool that opens up to the sky.
In a region where rain capture and reuse are uncommon, the permaculture principles underpinning the home challenge the traditional approach. “Recently, there has been a greater sense of urgency,” Javier says, “We are so far behind that we are in ‘debt’. To rebalance this reality, projects today need to generate surpluses, as it is not enough for buildings to be net zero if they can do more.”
“For us, the most sustainable designs are the ones that simply use less,” Robert says, further echoed by Javier, “By designing buildings to last longer, we won’t have to rebuild them, and together with integrating more flexibility, these buildings will be able to become part of new programs in the future.”
Not only does the integration of systems that leave a smaller footprint matter, but it is also the visual reminders of our reliance on the environment that may lead to meaningful change.
