ABERTO5 Exhibition Transforms Eduardo Longo's Casa Bola in São Paulo

The ABERTO5 exhibition is set to make its highly anticipated return to Brazil, taking over the distinctive spherical residence of architect Eduardo Longo, known as Casa Bola, in São Paulo. This event marks the fifth iteration of the acclaimed itinerant exhibition series, recognized for its innovative approach of repurposing architecturally significant, often previously unseen, private homes into captivating venues for contemporary art and design. From March 7th to May 31st, 2026, the public will have the unique opportunity to explore Longo's private dwelling, which will be transformed into an immersive gallery showcasing over sixty original and recent works by both Brazilian and international artists.

Casa Bola, an architectural marvel conceived and constructed by Eduardo Longo between 1974 and 1979, is a central feature of the upcoming ABERTO5 exhibition. This sculptural home appears to gracefully float above Longo's main residence, presenting a striking eight-meter diameter sphere made from ferrocement and recycled steel tubes. The design's singular, continuous interior eradicates traditional corners, with walls, furniture, lighting, and sanitary fixtures seamlessly integrated using the same material palette. The exhibition's organizers have embraced the home's unique geometry as an integral part of the curatorial process. Artworks are strategically placed along ramps, within intimate niches, or suspended from the dome, guiding visitors through a dynamic interaction with the architecture itself. Artists like Daniel Steegmann Mangrané, Sarah Lucas, Erika Verzutti, Laís Amaral, Paloma Bosquê, Tomás Saraceno, and Leonor Antunes have contributed pieces that respond directly to the unique spatial conditions of Casa Bola, transforming its curved surfaces and shifting scales into an expansive three-dimensional canvas.

The choice of Casa Bola as the exhibition venue adds a profound layer of intimacy and authenticity, as Eduardo Longo continues to reside in the home. This creates a compelling dialogue between daily life and curated artistic expression, where the traces of domestic routines subtly intertwine with the displayed works. Visitors will encounter archival drawings, sketches, and models that illuminate Longo's broader explorations into spherical housing, alongside newly commissioned pieces. The natural light filtering through the home's distinctive round windows casts moving circles across the floors, further enhancing the dynamic atmosphere where architecture, memory, and contemporary artistic production coalesce, each adapting to the constraints and possibilities of the other.

Beyond the confines of Casa Bola, the ABERTO5 experience will extend into the urban landscape of São Paulo through ABERTO Rua, a parallel public art initiative along Faria Lima. This street project will feature site-specific installations by Brazilian artists on sidewalks and plazas, engaging with prominent buildings by architects such as Ruy Ohtake and Isay Weinfeld. This expansion bridges the personal, intimate scale of Longo's home with the expansive public domain, fostering a connection between private artistic experimentation and broader civic engagement, further solidifying ABERTO5's impact on São Paulo's cultural scene.

The ABERTO5 exhibition offers an unparalleled opportunity to engage with contemporary art and design within an extraordinary architectural setting. By transforming Eduardo Longo's Casa Bola into a living gallery, the event not only showcases innovative artworks but also highlights the intrinsic relationship between space, art, and daily existence. This fifth edition reinforces ABERTO's tradition of creating immersive experiences that challenge conventional exhibition formats, bringing art directly into dialogue with its architectural context and extending its reach into the city's public spaces.

Studio for New Realities Reimagines Public Play Space in Rotterdam

The Studio for New Realities has successfully unveiled a groundbreaking lakeside pavilion at Plaswijckpark in Rotterdam, Netherlands. This project transcends the traditional playground concept, creating an inclusive, multi-seasonal hub where families can engage in play, learning, and imaginative exploration. A core achievement of this design is the re-establishment of a strong connection between the park and its adjacent waterfront, enhancing the natural appeal of the location.

A unique aspect of this development was the active involvement of children in the design process. Through their votes on preferred play equipment, young users directly influenced the final outcome, resulting in a building that caters to diverse activities from active play to creative endeavors, dining, focused learning, and experimentation. This new facility replaces an older theater and restaurant complex, now offering a versatile space that seamlessly merges the historical family park with the Bergse Achterplas lake.

Complementing the main structure, the studio also designed a secondary, entirely open-air pavilion. This lighter construction serves as a sheltered play area throughout the year. During winter months, it transforms into an ice-skating rink, supported by the main pavilion's culinary services. In warmer seasons, it functions as a shaded recreational zone and event venue. This adaptable space provides a dry haven during spring and autumn rain showers. Features like a central fireplace, integrated lighting, and a thoughtfully designed surrounding landscape ensure that this structure remains a welcoming communal spot, regardless of the season.

The genesis of this pavilion project was the unfortunate fire that devastated the park's theater in 2021. This event prompted the park's management to envision a new architectural landmark: the pavilion. The primary objective was to craft an inviting indoor environment that fosters play, education, and exploration, operable in all seasons, while also rejuvenating the park's intimate bond with the waterfront. Studio for New Realities meticulously integrated the outdoor areas, making them an intrinsic component of the overall experience and expanding the realm of play beyond the building's physical boundaries.

The pavilion further enhances programmatic synergy by consolidating functions previously housed in a standalone restaurant and a seasonal ice rink into one cohesive design. Contextual integration was a paramount principle for the pavilion's development. Its completion physically and visually re-establishes Plaswijckpark's connection with the lake, optimizes internal pathways, and introduces a new natural zone, complementing the existing play, animal, and park areas.

Instead of conceiving the pavilion as a singular, imposing structure, the architects opted to segment its required volume into smaller, more proportionate elements. This approach ensures that the new additions harmonize with the scale of other buildings within the park and along the waterline. The design prioritizes low-tech solutions and utilizes durable, timeless materials that naturally blend with the serene green shoreline. The introduction of new trees and a carefully sculpted natural embankment further amplifies the tranquil ambiance of the site. Positioned as an anchor on the lakeside, the pavilion is complemented by adjusted pathways that forge more logical connections between the various sectors of the park. Facing the park, the building opens onto an active forecourt and terrace, designed to be inviting spaces that encourage family gatherings and social interaction.

A distinctive, expressive roof structure, reminiscent of a tent, unifies these disparate volumes. This lightweight, folded roof honors the legacy of existing park pavilions while facilitating a seamless transition between indoor and outdoor environments. The larger sections, encompassing the playscape and restaurant, feature maximum transparency to preserve unobstructed views of the lake. Expansive windows, multiple entry points, protective overhangs, and strategically placed roof openings reinforce the connection with the surrounding landscape, allowing visitors to immerse themselves in the changing light, weather patterns, and seasons. Rooftop terraces on the upper level provide direct outdoor access from studio rooms, offering panoramic views of both the park and a secluded play area. More private sections accommodate back-of-house functions, characterized by thoughtfully selected materials such as timber facades with open joints that extend from exterior to interior, and a maroon-hued zinc roof that blends harmoniously with the natural setting.

The design team embraced a usage-centric methodology, crafting the building to actively encourage and facilitate engagement by children and their families. Inside, the experience is enriched by playful and creative 'activators.' These include an oversized stair-landing that doubles as an open studio, tiered seating arrangements, precisely positioned skylights and windows that frame specific vistas, a secluded sensory nook, a comprehensive book wall, a relaxing chill net, and numerous informal seating zones. These thoughtfully integrated elements stimulate movement throughout the building, heighten the appreciation for weather and natural light, and organize the interior space in an intuitive and engaging manner.

This innovative concept envisions the building as a dynamic 'usage machine,' a diverse collection of spaces each imbued with a distinct atmosphere, robust indoor-outdoor connections, and architectural features designed to inspire active exploration. The pavilion is organized as a fluid sequence of flexible and specialized areas, incorporating expansive open zones for communal activities, more intimate enclosed rooms for smaller groups, and dedicated workshops and craft zones. This adaptable design ensures the building can host a broad spectrum of activities, evolving with the changing seasons.

The Plaswijckpark Pavilion by Studio for New Realities represents a thoughtful architectural endeavor that prioritizes community engagement and a holistic approach to public space design. Its innovative blend of functional versatility, aesthetic appeal, and natural integration sets a new standard for recreational and educational facilities. The inclusion of children's perspectives in the design process further underscores its commitment to creating a truly user-centric environment that fosters joy, learning, and connection with nature.

Petokka: Transforming Robotic Vacuums into Playful Companions

In an era where technology seamlessly integrates into our daily lives, even household appliances are undergoing a transformation from mere utility to personalized companions. The introduction of Petokka by ZakkaGyou studio marks a significant shift in how we perceive and interact with our robotic vacuum cleaners, imbuing them with character and charm. This innovative decorative set, designed with both aesthetics and subtle functionality in mind, allows users to transform their cleaning devices into engaging, pet-like figures, fostering a deeper, more emotional connection with everyday technology.

Petokka not only taps into the growing trend of personalizing domestic gadgets but also cleverly leverages the inherent movements of robotic vacuums to create dynamic visual effects. The flexible ears that fold under furniture and the expressive face elements that react to obstacles are testaments to a thoughtful design approach that prioritizes user engagement and aesthetic integration. This creative solution elevates the humble vacuum cleaner from a mundane chore-doer to an animated participant in the home environment, reflecting a broader societal desire for products that offer more than just practical benefits.

The Genesis and Design Philosophy Behind Petokka

ZakkaGyou, a Tokyo-based design studio, conceptualized Petokka as a distinctive decorative addition for autonomous cleaning devices. This accessory comprises a facial component and a pair of attachable ears, ingeniously crafted to convert standard robotic vacuum cleaners into endearing, simplified representations of beloved animals, such as felines or canines. The core innovation lies in its ability to introduce an engaging visual layer that harmonizes with the robot's operational movements, without imposing any alterations to its fundamental cleaning capabilities. This thoughtful design emphasizes a non-invasive approach to personalization, allowing the device's original function to remain uncompromished while significantly enhancing its aesthetic appeal and user interaction.

The meticulous design of Petokka ensures that its decorative elements are not merely static but interact dynamically with the robot's environment. As the vacuum navigates through living spaces, the pliable ears are engineered to bend fluidly when passing beneath furniture, and the facial features subtly shift or react upon encountering obstructions. These responsive attributes are achieved through the inherent material properties and mechanical design of the components, rather than relying on complex electronic modifications. By harnessing the robot's pre-existing motion, Petokka generates nuanced and captivating visual changes throughout its cleaning cycle, thus transforming a routine task into a more whimsical and animated experience for household members.

Customization and Material Innovation for Enhanced User Experience

The creation of Petokka by ZakkaGyou studio is a direct response to the escalating popularity and ubiquitous presence of robotic vacuum cleaners within modern households, particularly the circular, self-navigating models that have become fixtures in residential interiors. As these devices have evolved from purely functional tools to integrated elements of home life, there's been a noticeable rise in consumer demand for customization and personalization. Petokka addresses this trend head-on by providing a standardized yet highly effective method for users to inject individuality into their appliances without compromising their integrity. This product exemplifies how designers are creatively meeting the desire for domestic items that are both practical and aesthetically pleasing, aligning with personal tastes and preferences.

The nomenclature "Petokka" itself is a playful adaptation of the Japanese phrase "ペット化" (petto-ka), which translates to "to make something into a pet," deliberately modified to convey a lighthearted and engaging character. This naming reflects the product's core aim: to transform inanimate objects into companions. Users are presented with a variety of face designs, allowing them to select options that either appeal to them generally or even mimic the appearance of their own actual pets, enhancing the personal connection. Constructed primarily from PLA plastic, Petokka's main components are durable, while the ears are fashioned from natural rubber, chosen for its flexibility and resilience against repeated bending. The product's packaging further extends this concept, designed with folded thick paper featuring embossed facial details and tail and paw-shaped attachments, ensuring the pet-like aesthetic is evident from the moment of unboxing to its installation on the robot.
