The Lotus Cafe: Engineering a Floating Structure

The visual ease of The Lotus Cafe at the Dasavatara Hotel in Tirupati hides a complex structural reality. Achieving that floating effect required precise engineering for the folded-plate roof, ensuring it remained light yet robust. We balanced the structural weight with floor-to-ceiling glass walls, creating a seamless transition between the dining space and the reflective pool.

Architecture often demands that we reconcile the heavy with the light. In this project, the goal was to create a cafe that appeared to hover above the water, grounding itself only through reflection.

The Engineering Narrative

The folded-plate roof was the central design challenge. It needed to provide shelter without feeling oppressive. By employing a faceted metal structure, we achieved a silhouette that responds to the surrounding Tirumala hills while allowing the roof to taper into an incredibly thin, light edge at the perimeter.

Material and Climate Strategy

We used the glass facade not just for aesthetics but to control the interior environment. The large panes dissolve the wall, bringing the outside in, while the reflective pool acts as a passive cooling element, moderating the temperature before air enters the building. This climate-responsive approach is a hallmark of our work at SJK Architects—every aesthetic decision serves a functional purpose in the building's performance.

Execution as an Orchestra

For us, this is never just about a drawing. It is about the assembly. We spent significant time on-site supervising the casting of the concrete and the assembly of the steel structure to ensure the geometry remained sharp. The result is a space that changes throughout the day, as the sun moves across the water and the roof, shifting the cafe’s character from a bright morning retreat to a quiet, illuminated pavilion in the evening.
