Designed by K-Square Architects, TERNS in Coimbatore, India, is a hospitality destination that brings together architecture, landscape, and experience. Conceived as a restaurant-bar and leisure venue, the project balances expressive architectural form with a response to site constraints, climate, and programmatic flexibility.

Rather than relying on a conventional enclosed building, the design unfolds through a sequence of open and semi-open dining environments arranged around a central water spine. Sloping roof planes, transparent facades, and layered landscape elements shape a setting that blurs boundaries between indoors and outdoors. At the same time, the project adopts a lightweight steel structural framework that allows the complex to remain temporary, removable, and adaptable—an approach that reduces long-term environmental impact while enabling future reuse.

Between urban edge and open landscape

The project site is located near Civil Aerodrome Post in Coimbatore, an area positioned at the intersection of the city’s expanding urban edge and its quieter semi-rural surroundings. The context consists of low-rise residential neighbourhoods, scattered industrial developments, and pockets of open fields. The environment is characterised by movement, vehicular traffic, and evolving urban activity.

Within this setting, the design strategy was to create an inward-facing environment rather than compete with surrounding visual noise. By turning the architectural focus toward a landscaped interior core, the project establishes a microclimate and a sense of detachment from the surrounding bustle. The result is a spatial sequence of outdoor and semi-indoor spaces connected to greenery and water.

Flexibility and temporary construction

The vision was to transform an empty plot into a hospitality destination capable of accommodating diverse visitors, from families and casual diners to social gatherings and evening crowds.

Alongside the restaurant-bar programme, the client also proposed compact hotel blocks that could host overnight guests. Because the land is leased, a requirement was that all structures remain temporary, removable, and potentially reusable. This constraint influenced the architectural approach. Instead of permanent masonry construction, the project was conceived as a steel-and-glass framework that allows rapid assembly, structural efficiency, and future adaptability. The removable framework reduces long-term site impact and allows the architecture to adapt or relocate in the future.

Speed and structural expression

The project was designed, constructed, and operational within a 15-month period. A prefabricated steel structural system enabled rapid fabrication and efficient on-site assembly, allowing the design to meet this schedule without compromising spatial intent. Structural elements are intentionally expressed rather than concealed, contributing to the architectural identity.

One of the project’s defining features is the roof composition formed by large, tilted planes. Conventional edge-supported columns would have weakened the visual effect of these cantilevers, so the design introduced a system of V-shaped columns emerging from the floor and branching outward to support the roof. Once the interior is furnished and active with visitors, these supports visually recede, allowing the roof planes to read as floating elements.

In the indoor dining areas, the primary supports shift toward the perimeter and are wrapped in glass façades, reinforcing the perception of openness and lightness.

A water-centred courtyard

At the heart of TERNS lies a central courtyard that functions as the project’s spatial anchor. A 23-foot freestanding water cascade and a linear reflecting pool divide the built mass into two primary wings. Both indoor and semi-outdoor dining zones are oriented toward this courtyard, ensuring that water and landscape remain the visual focus from most vantage points. The linear pool extends into the required open setback area, transforming regulatory restrictions into a landscaped spine that buffers the project from surrounding activity. The presence of water also plays an environmental role. By introducing evaporative cooling and reflective surfaces, the courtyard helps moderate microclimatic conditions and enhances the comfort of semi-open dining areas.

Multi-level movement and elevated views

The courtyard incorporates tiered dining platforms at multiple elevations. Visitors encounter dining pockets at different levels, creating varied perspectives across the water body and cascade.

A floating bridge deck spans above the central pool and is accessed through a sculptural spiral staircase. This elevated walkway introduces vertical circulation and offers a vantage point across the courtyard. As guests move through the space, walking across the bridge, ascending the stair, or dining at different levels, the environment becomes animated by overlapping paths and visual connections. This layered movement contributes to the project’s social activity while maintaining visual coherence.

Roof geometry and visual orientation

The roof composition plays a key role in shaping the architectural identity of TERNS. Three tilted roof planes define the overall form. Two of these planes rise from approximately 12 feet at the outer setback edge to nearly 25 feet toward the central courtyard, directing views inward toward the landscape core.

The third roof plane slopes toward the landscaped setback near the parking area. A glass façade and planted buffer zone were introduced here to prevent direct views of vehicular movement, ensuring that the visual focus remains on greenery and water. Together, these angled planes create a silhouette that reinforces the inward-oriented spatial experience.

Materiality and interior atmosphere

While the structural system relies primarily on steel and glass, the interior material palette introduces warmth and tactility. Timber-finished ceilings, exposed concrete textures, granite flooring, rubble stone cladding, and corten steel accents create a layered material environment that complements the surrounding landscape.

Lighting installations animate the interiors. Pendant lights frame the bar and dining areas, while decorative ceiling elements and suspended installations shift the atmosphere from daytime calm to evening activity. In the café zone, clusters of lantern-like fixtures soften the atmosphere, balancing the expressive structure with a more intimate scale. These elements work together with landscape planting and water reflections to create a spatial experience that evolves throughout the day.
