We were both born in Peru and we lived here up until university. The country, it seems, has been permanently in crisis. We have had so many Trumps in our times, only less powerful. We have suffered a lot, politically and economically. What we loved about this project was that it’s a very different kind of museum — one of memory, of place and of remembrance — compared to similar museums in other Latin American countries. And the necessity to heal wounds didn’t come from the government but from the people.

So instead of it being a top-down process, it was a bottom-up process, one contested by the government because a wide political spectrum, from left to right, came together and decided that what was initially a report on reconciliation [headed by Nobel laureate Mario Vargas Llosa] should also be a place where people reconcile. It was very symbolic. And the fact that the government didn’t like it legitimized it.

It was also an important project because we had to ask the question, “What is the relationship between architecture and memory?” And those tragic memories, specifically. Is architecture going to express those horrors or not? In the competition for the commission, we asked all these questions and decided to work instead with other memories: with the memory of territory and of place — that site in particular, on the coast bordering Lima. In the end, it is a building made only by the structure and the light; you have no other elements. Its austerity is vigorous.

The origin of that building was a government scholarship that allowed students from low-income and rural families to study in private universities. There are very few good public universities here. The university embraced the scholarship and accepted 800 new students and commissioned this building to accommodate the larger cohort. One of the big issues was how the new students who come from the fields would intermix with more urban, wealthier students outside of the classrooms. It was determined that we should provide spaces for these encounters between them — and also because we know now that real learning does not necessarily occur in classrooms, but in the spaces between classrooms.

Also, in climates like ours, providing lots of non-programmatic spaces is very cheap — you don’t have to insulate them, waterproof them, heat them or cool them. You only have to provide really passive means of comfort. So that was our foundation for expressing another idea that is very important to us: Architecture has to be generous. We need more of these types of places, as the pandemic is reinforcing. We need more generosity everywhere and especially in architecture.

Form is a consequence of the environment. It’s not form follows climate, but form follows environment.

With Casa Huayoccari, we wanted to resonate with the surrounding mountains, so it came naturally to work with this big roof. We were really working with the landscape as the Inca did. We organized the land and then the house as a series of platforms. The Inca transformed the landscape with terraces; we did the same, and only covered those terraces with a roof that has this shape of the mountains. We worked with a version of the passive roof to create the courtyard, for intimacy. You have different types of spaces in this sequence of exterior spaces: the terrace, the loggia, another courtyard, then another terrace. It’s related to the idea of experiences — actually experiencing the house, and not having it exist as an isolated object.

We like to work with the things that are easily available in the places we build. The absence of rain, the mild climate and the barren landscape are materials, too — just like concrete is. If we work with concrete, it’s for two reasons: The main reason is the fact that we often work on the Peruvian coast, which is a desert. And people here know how to build in concrete, which means we can hire local. The second reason is that we’re always trying to merge with the landscape, not by doing architecture that erases itself, but by doing architecture that is one more layer in the landscape: It has its presence but at the same time is dependent on the landscape, just as the landscape is dependent on the architecture.

One way to do it is to have the same hue as the desert. And we find concrete is the best way to do that, not because we put aggregates or colour additives into the concrete, but because there’s a lot of dust in the desert. The type of concrete we use, and how we form it, absorbs the dust so that in very little time our buildings are exactly the same colour as the desert.

In relation to the section, we have found that, in a plan, you might be able to explain how people move in a building and how it’s organized, but you can’t explain the space. The section explains the strategies of how space and light and territory and topography are worked in. For us, it’s impossible to think about topography or space or light in a plan.

In part. Also, I think it was the opportunity to try to do a different architecture, based on what we saw as problems to be solved. We always love to find opportunities in problems. And returning to Peru opened up a new set of problems: working with the little means we have, economic and technological restrictions.

It was also about rediscovering craftsmanship, which in Europe is gone when it comes to normal buildings, though you might have good craftspeople if you’re restoring places like the Louvre or Versailles. Here in Peru, builders are still worried about building well. Not perfectly, but well. And in general, in all developed countries, financing and insurance companies are now dictating what can and can’t be done by architects. There is very little space, unless you’re a rock-star architect, to do research and innovation in architecture.

There are also many things here that are truly advantageous. For example, we have an incredible temperate climate that allows us to do architecture with the essential elements; we try to enhance space with structure, and not add anything else. And here, you don’t need layers of protection, and so you can really have a more direct relationship between interiors and exteriors, extending the former into the latter.

We were fascinated by these possibilities, and now that we’ve experienced them and learned to value them, we incorporate them in our work. Our houses in Peru, which we started in Paris and pursued when we moved here, were a laboratory to test our strategies. When we had the opportunity to do Casa Huayoccari in the Andes, it was challenging because the climate was different from the desert, but we wanted to work with these same types of spaces.

And also to work with the notion that architecture is beyond a shelter, and beyond the notion of shelter. Working in this place, architecture really relates less to the loggia, the hut or the cave as an archetype and more to Stonehenge. It’s more about a relation to the cosmos.

And to the territory.
