Tanatap Frame Garden By RAD+ar

Tanatap Frame Garden, designed by RAD+ar (Research Artistic Design + architecture), is an experimental restaurant, coffee shop, and art gallery located in Jakarta, Indonesia. Completed in 2023, the 1,300 m² project reimagines how commercial architecture can coexist with public parks, tropical climates, and community-driven activities. Rather than presenting itself as a conventional building, Tanatap Frame Garden operates as a multi-leveled walkable garden, blurring boundaries between architecture, landscape, and civic space.

Architecture Without a Facade

At the core of the design is a provocative question: What if architecture had no facade? Instead of defining the building through walls or elevations, RAD+ar proposes a facade-less architecture where activities, movement, vegetation, and framed views become the building’s identity. The structure acts as a framed garden, allowing the public park to visually penetrate the café while simultaneously turning visitors into living exhibits within the urban landscape.

The building is accessible from all directions, rejecting traditional front-and-back hierarchies. This openness reinforces Tanatap’s ambition to function as a new civic living room—a place for gathering, exhibiting art, relaxing, and social exchange.

Framing Nature, Framing People

A defining feature of the project is its playful use of four different frame types—stainless steel, artwork frames, glass, and GRC—strategically placed to manipulate perspective. These frames create layered visual experiences where visitors observe the park, while passersby see the café as a living gallery. Architecture, landscape, and human activity continuously frame one another, creating a dynamic and ever-changing spatial narrative.

Sequential Spatial Experience

Tanatap Frame Garden is conceived as a sequence of spaces rather than a single defined room. Visitors enter beneath a compressed ceiling height of 2.2 meters, which gradually expands to 7.5 meters as they move deeper into the building. This intentional manipulation of scale heightens spatial awareness and culminates in a dramatic, multi-level garden space that unfolds vertically and horizontally.

A rainbow-tinted skylight positioned at the heart of the structure allows sunset light to penetrate deep into the café, reinforcing a sense of warmth, temporality, and connection to nature.

Tropical Passive Design and Low-Energy Strategy

Built within a dense residential neighborhood with extreme heat conditions, Tanatap Frame Garden demonstrates how passive design strategies can support both environmental sustainability and commercial viability. The porous structure promotes cross-ventilation through a wind-tunnel effect generated by the framing system. Double shading, floating garden platforms, and minimal enclosure significantly reduce reliance on mechanical cooling.

Rather than maximizing built mass, the project optimizes negative space, allowing air, light, and greenery to define comfort. This approach proves that low-energy tropical commercial architecture can remain profitable and socially engaging in developing cities.

Geometry, Landscape, and Urban Integration

Formally, the architecture explores simple geometric volumes, carved by symmetrical ground-floor layouts and contrasted with an organic amphitheater-like garden on the upper level. The roofscape doubles as a walkable landscape, extending the adjacent public park and offering elevated views of the surrounding greenery.

The design process was reverse-engineered from the landscape outward, ensuring that architecture serves as an extension of nature rather than its replacement.

Architecture as Social Experiment

Beyond its physical form, Tanatap Frame Garden functions as a behavioral and social experiment. Furniture elements are intentionally ambiguous—blended into hardscape and landscape—encouraging visitors to define their own modes of comfort and interaction. RAD+ar uses the project to study how people reinterpret space when traditional spatial hierarchies are removed.

This adaptability allows the café-gallery to shift identities throughout the day, responding organically to crowds, events, exhibitions, and informal gatherings.

A New Model for Sustainable Commercial Public Space

Tanatap Frame Garden stands as a prototype for sustainable, community-driven commercial architecture in tropical urban environments. It demonstrates how business, art, landscape, and environmental responsibility can coexist without sacrificing spatial richness or profitability.

By transforming a café into an open, framed garden, RAD+ar offers a compelling vision of architecture as an evolving public platform—one that invites exploration, creativity, and shared ownership.
