BIRI's Casa Castela, nestled in Nova Lima, Brazil, showcases a masterful integration of architecture with its demanding natural surroundings. The design ingeniously navigates a significant thirteen-meter elevation difference, transforming what could be an obstacle into a defining characteristic of the property. This residential project not only addresses the functional needs of its inhabitants but also creates a dynamic relationship with the landscape, leveraging the site's verticality to shape a unique architectural journey.

The genesis of Casa Castela began with a careful site selection process, where BIRI architects collaborated with the clients to choose a location that offered both breathtaking views and practical accessibility. The chosen plot presented a dual challenge: a dramatic slope and an existing incomplete structure. Rather than demolishing and rebuilding, the architects embarked on a comprehensive analysis of the existing elements, conducting detailed topographic surveys and refining the spatial brief to harmonise with the environment.

A key aspect of the design is its innovative circulation system. Instead of merely overcoming the steep terrain, the design embraces it. An elevator and an elevated metal walkway gracefully traverse the incline, connecting the street level to the main entrance of the house. This deliberate transition allows residents and visitors to experience the landscape gradually, turning a simple journey into an observational sequence. This distinctive access route also serves as a visual landmark within the local architectural context. At the base of the property, robust reinforced concrete retaining walls are strategically employed to create functional parking areas, seamlessly carved into the hillside. Similarly, at the rear, a protected courtyard is formed through careful excavation, separating the living spaces from the natural ground and mitigating moisture while offering a secluded outdoor sanctuary.

The internal layout of Casa Castela, meticulously planned by BIRI's architectural team, establishes a clear distinction between communal and private zones. The upper level is dedicated to private quarters, housing a master suite and two children's bedrooms that share a connecting bathroom. The ground floor serves as the hub for social and shared activities, featuring a spacious living room, dining area, an atelier, a ping-pong room, and a kitchen. Practical service areas, such as storage and laundry facilities, are thoughtfully positioned on the western side, ensuring that the primary living spaces remain open and connected to the exterior environment.

Connecting these two distinct levels is an internal staircase, a blend of steel and reinforced concrete, reflecting the layered structural elements used throughout the construction. The material palette for the house draws inspiration from regional building traditions, incorporating reinforced concrete for the primary structure, ceramic masonry for the walls, aluminum window systems, and traditional ceramic roof tiles. Notably, steel components like the pergola, elevator structure, and walkway are finished in earthy tones, echoing the iron-rich landscape characteristic of Nova Lima. The interior design further enhances the house's artistic ambiance, with paintings, canvases, and personal artifacts thoughtfully integrated into the living areas. Lighting is employed with subtlety, accentuating the spatial arrangement, material textures, and carefully chosen interior elements without overpowering the overall atmosphere.

Ultimately, Casa Castela stands as a testament to thoughtful design that respects and responds to its environment. BIRI's vision transformed a challenging site into a harmonious residence, where every architectural detail contributes to a cohesive and enriching living experience, demonstrating how constraints can lead to creative and impactful solutions.

Gijs Van Vaerenbergh's "CLAUSURA" art project offers a compelling reinterpretation of the historical Herkenrode Abbey in Belgium. This large-scale intervention reconstructs the abbey's lost core through an intricate steel framework, providing a 'ghost-like' outline of its vanished cloisters. Commissioned by the Flemish heritage organization Herita, the installation aims to resurrect the abbey's historical presence without literally rebuilding it. Thin steel tubes meticulously trace the contours of the absent structures directly onto the landscape, creating a dynamic visual experience where architecture alternates between clear visibility and subtle disappearance, inviting viewers to actively engage with the site's rich past.

Herkenrode Abbey, established in the late 12th century, was once a thriving Cistercian monastery in the Low Countries. Over centuries, it expanded to encompass extensive cloister gardens, galleries, convent buildings, infirmaries, and a Gothic church. However, due to various historical events such as fires, decay, and demolitions, most of its central edifices were lost, leaving only fragmented remnants of the original complex today. The CLAUSURA project seeks to bridge this gap, allowing contemporary visitors to visualize the grandeur of the abbey as it once stood.

The Belgian artistic duo, Gijs Van Vaerenbergh, conceptualized a spatial drawing that restores the abbey's ensemble through precise outlines, rhythmic patterns, and varying perspectives. The installation faithfully recreates the missing buildings at their original dimensions and locations using a lightweight grid of steel tubes. This design allows the structure to appear to dissolve into its natural surroundings, offering a constantly evolving perception depending on the observer's viewpoint. The interplay of light and shadow, combined with the visitor's movement, brings elements like vaults, windows, towers, and rooflines into temporary focus before they recede into abstract forms.

Beyond merely outlining vanished structures, the project also integrates new steel frameworks with existing remnants of the sisters' quarters, infirmary, and arcade. These additions stabilize and extend the surviving masonry, replicating former roof structures and creating sheltered spaces for temporary use, thus preserving the historical integrity while adding new functionalities. This approach reflects Gijs Van Vaerenbergh's ongoing exploration of architecture as a perceptual experience, turning buildings into drawings, atmospheres, or optical illusions, as seen in their previous works like "Reading Between the Lines" and "Labyrint."

At Herkenrode, this methodology renders absence spatially tangible. Visitors navigate a reconstructed void where the essence of the architecture endures as an outline, transforming heritage into an active dialogue between what remains, what has disappeared, and what can still be imagined. The CLAUSURA project is being executed in three phases, with the initial and most extensive phase scheduled to debut on June 18th, 2026. This initiative not only brings a forgotten past to life but also highlights the studio's profound engagement with themes of reconstruction, erosion, and architectural memory, offering a powerful reflection on the ephemeral nature of built environments.

On Chuanchang Island in China, Studio 10 has meticulously integrated a unique architectural creation, the Wetland Caves Pavilion, within a vibrant wetland landscape. This distinctive site, shaped by the relentless processes of erosion and sedimentation from the Qu River, supports a diverse ecosystem, rich in plant and animal life. The expansive mudflats along the island's perimeter provide varied settings for people to engage with the natural beauty and ecological dynamics of the wetlands. Echoing the historical presence of ancient caves scattered across the shoreline, this contemporary intervention harmoniously merges human construction with nature, evoking a profound sense of continuity and enigma.

The conceptual framework for the pavilion draws inspiration from the island's annual cycle of flooding and receding waters, which continuously reshapes the terrain and regenerates wetland meadows. The design reflects a deep appreciation for this natural rhythm, seeking to blur the lines between human intervention and environmental preservation. Studio 10's innovative approach explores the delicate interplay between aquatic and terrestrial systems, creating a sanctuary that serves both local fauna and human visitors. Within this dynamic zone, where boundaries are perpetually in flux, an abstract artificial cave structure emerges, offering refuge for animals, facilitating water access and resting spots for villagers, and providing an immersive platform for guests to explore and observe the wetland's delicate balance.

The pavilion's structure is characterized by a series of strategically placed concrete pillars, reminiscent of ancient cave formations and natural waterholes, which subtly anchor the building within the fluid wetland environment. These pillars are not merely structural; some are ingeniously hollowed out to accommodate various functions, such as waste collection, water provision, birdhouses, and observation posts. These interior 'voids' extend and interact with the exterior, puncturing the thick concrete walls to create skylights, side windows, and openings that ensure natural ventilation, ample lighting, and captivating views of the surrounding landscape. Topping these concrete forms are prefabricated light steel bamboo roofs, whose modular grid system pays homage to traditional local bamboo craftsmanship, sourcing materials sustainably from nearby forests. Additionally, hidden planters at the apex of the concrete pillars encourage native climbing plants to flourish, offering natural shade and further integrating the structure into the lush green environment, fostering a seamless blend of design and ecology.

This thoughtful design not only enhances the visitor experience but also underscores the profound connections between human culture and the natural world. The pavilion's materials and colors are carefully chosen to resonate with the textures of the ancient caves and the natural weathering of the landscape, creating a dialogue between the past and the present. It serves as a testament to the elegance and poetry of natural laws, inviting observers to witness and participate in the ongoing story of the wetlands. Through this project, Studio 10 successfully crafts a public space that harmonizes natural and constructed elements, providing a place for contemplation, interaction, and a heightened awareness of our ecological responsibilities, inspiring a positive engagement with the environment.
