PEDRE, a multifamily housing complex located near the Pedregal de San Ángel Ecological Reserve in Mexico City, is centred around a forward-thinking architectural approach that works with its natural and cultural surroundings. Designed by the collaborative efforts of Mexico-based architectural firms JSa and MTA+V, this structure addresses the pressing need for housing while enhancing the ecological and aesthetic value of its environment.

At its core, PEDRE embodies a design philosophy that seeks to transform traditional residential architecture. The Mexican architects challenge the conventional box-like structures and instead opt for a fluid and organic form that integrates various extensions such as patios, corridors, terraces and stairs. This design strategy is rooted in a participatory process that brings together expertise from architecture, engineering, urbanism, landscaping and interior design. The designers' goal was to create a resilient and adaptive structure that fosters community interaction while respecting the site's ecological context.

This is evident in PEDRE's architectural form which is characterised by its three lobes that radiate from a central circular atrium. This atrium serves as the heart of the building, allowing natural light to penetrate deep into the residential interiors while promoting social interaction among residents. The lobes are designed to echo the lava folds of the surrounding landscape, effectively doubling the building's perimeter compared to traditional rectangular designs. This unique morphology enhances aesthetic appeal and also optimises views and access to outdoor spaces. This is also a response to the unique shape of the site.

Talking about the experience of the design and execution of the residential architecture project, JSa and MTA+V said, "The triangular shape of the lot presented a unique challenge that required us to rethink conventional approaches. Moving away from traditional geometric forms, we developed an amorphous, three-branched design that not only maximised the building’s perimeter within a compact space but also enhanced natural light and ventilation. Achieving this distinctive shape demanded innovative structural engineering and construction techniques, made even more complex by delays and cost increases during the pandemic. Despite these hurdles, the result is a dynamic architectural solution that balances functionality with an organic connection to its context."

The building rises 14 stories high and houses 112 apartments across 18 different typologies, ranging from 90 to 300 square metres. Each unit features its outdoor space, encouraging a seamless connection between indoor and outdoor living. The radial core acts as the backbone of the structure, supporting the dynamic forms that unfold towards the city.

Achieving the building’s distinctive shape required sophisticated structural engineering and innovative construction techniques. Most of the building’s elements are prefabricated off-site through a combination of the BubbleDeck and Aircrete systems.

“It was a long and complex process that also went through pandemic-related delays, but in the end, this approach allowed us to reduce the required concrete to a minimum, while also being able to achieve an optimised and clean structure with no visible beams,” continued JSa.

The choice of materials in PEDRE reflects a commitment to sustainability and eco-compatibility. The facade is constructed from exposed concrete, aluminium and glass, creating an elegant interplay between solids and voids. This careful proportioning ensures that each apartment enjoys ample natural light while maintaining privacy through strategically placed vertical aluminium fins.

Innovative construction methods are employed throughout the project, including BubbleDeck lightweight slabs and Aircrete prefabricated concrete walls. These techniques are crucial in optimising the resource efficiency of the building by reducing the waste that is typically generated during construction. It also aids in increased structural integrity. The use of endemic vegetation in landscaping further emphasises PEDRE's dedication to preserving local biodiversity while enhancing the overall aesthetic quality of the environment.

One of PEDRE's most significant achievements is its ability to integrate seamlessly with its surroundings. The project acknowledges the historical context of El Pedregal—an area known for its volcanic rock formations—and pays homage to its industrial past through thoughtful design choices. The building’s morphology interacts with public spaces through access points, sidewalks, bays and lobbies that contribute to the collective memory of the region.

Open spaces, recreational areas, and circulation paths make up 30 per cent of the site, inviting residents and visitors to engage with their surroundings. This balance between built and permeable areas enhances community connectivity and contributes positively to urban ecology by improving air quality and reducing noise pollution.

The residential design of PEDRE emphasises community living by fostering social interactions among residents. The central atrium is a communal space where neighbours can gather, enhancing a sense of belonging within the complex. This focus on connectivity is further reflected in the building's layout, where hallways are designed not just as passageways but as sculptural elements that encourage casual encounters.

By integrating public spaces into its design framework, PEDRE promotes inclusivity and engagement through community architecture. The project aims to create unique living experiences that address cultural, social and economic aspects of life in El Pedregal while providing high-quality housing options. It is a testament to contemporary architecture's potential to harmonise with nature while addressing urban challenges. Its innovative design transcends traditional residential models by embracing fluidity, sustainability and community interaction. Through thoughtful integration with its ecological surroundings and cultural heritage, PEDRE not only enhances the urban landscape of Mexico City but also sets a benchmark for future architectural endeavours.

The project's successful balance between density and permeability highlights an evolving understanding of urban living—one that prioritises both individual comfort and collective well-being. As cities continue to grow and evolve, projects like PEDRE will play a crucial role in shaping resilient communities that thrive in harmony with their environment.
