Cerron Arquitectos Lines the CASACOR Peru 2026 Entrance with Bamboo Canopies Shaped Like Flower Petals

Most design fairs treat their entrance as a formality: a gate, a ticket desk, a corridor you hurry through to reach the rooms everyone came to see. For CASACOR Peru 2026, held at the Jockey Club del Perú in Santiago de Surco, Cerron Arquitectos took the opposite position. Their Umbral Floral Pavilion spreads 120 m² of bamboo canopies along the main access path, turning a plain circulation route into a sequence of small public rooms set between mature street trees.

"Umbral" means threshold, and the name is the real brief. The project's argument is that the walk in is part of the exhibition, a transition between the city, the planted grounds and the show inside. What makes it worth your attention is how little it needs to make that case. Several splayed bamboo structures, each opening like a flower into a gridded roof, are placed carefully among existing trees. The result is closer to landscape furniture than to a pavilion in the object-on-a-plinth sense.

A Path Recast as a Sequence

Seen down the length of the road, the canopies read as a rhythm rather than a single statement. They sit at the edge of the paving, alternating with tree trunks, so the walker passes from open sky into filtered shade and back again. That repetition is what does the work of a threshold. One canopy would be a kiosk; a line of them becomes a procession.

We like that the architects did not try to close the route or build a tunnel. The road stays a road. The intervention only thickens its edges, which keeps the flow of a crowded fair intact while giving people a reason to slow down.

The Petal as Structure

Each unit starts from a tight cluster of poles at the ground and fans outward and upward into a lattice roof. From the front the shape reads as a funnel; from an angle it tilts like a petal lifting off a stem. The two- and three-petal variants share the same logic, so the family looks consistent without every piece being identical.

The open grid roof is a deliberate choice. It does not keep out rain or sun completely. It breaks the light into patterns and lets the tree canopy above remain visible. On a site where the trees are already the main source of shade, a solid roof would have competed with them. The lattice cooperates.

Building Under the Trees

The most convincing images are the ones where bamboo and tree occupy the same space. Slanted poles slip beneath a thick limb, and the lattice ends just short of a leaning trunk. Looking up through the lashed culms, you see leaves rather than sky. The plans confirm this was planned: each canopy is placed in the gap between two tree crowns, sized to the space the trees leave.

This is the quiet discipline of the project. Rather than clearing ground for a showpiece, the designers treated the existing trees as fixed elements and fitted the new structure into what remained. For a temporary installation, that respect for the host landscape matters as much as the structure itself.

Bolts, Rope and the Honest Joint

Up close, the construction is plain to see. Poles are bolted where loads concentrate and lashed with rope where rods cross and fan out. The open ends of the culms point at the sky without caps or trim. Nothing is hidden behind cladding, which suits both the material and the temporary nature of a fair.

Bamboo is the material Cerron Arquitectos keeps returning to across its practice, and this project reads as a confident use of that expertise at a public scale. The firm has also described Umbral Floral as reinforcing the value of collective construction. Connections that combine simple bolts with hand lashing are the kind a team can learn and repeat, so that idea is visible in the joints themselves.

Places to Stop

Wooden loungers and a pair of cane armchairs sit on the lawn beside the canopies, against clipped hedges. They are small additions, but they change how the path is used. A visitor waiting for a friend, or recovering after a long tour of the show rooms, now has somewhere to sit that is neither the street nor the exhibition.

Gravel pads under each canopy mark the zone without hard edges. The ground treatment is modest and reversible, which is the right instinct for a structure meant to serve a single season of the fair.

Plans and Drawings

The concept sketch traces the design from a five-petal flower seen from above, to separated petals, to the first timber structure. The perspective sketch shows the intended mood: slender splayed columns, a lattice roof and people talking along a tree-lined path. It is an unusually direct line from metaphor to built form.

The site plan and individual canopy plans are the most revealing set. Each fan of radiating ribs is drawn between two tree crowns, and the canopy geometry clearly follows from that spacing. The elevations and rendered views show the curved supports and gridded roofs at the scale of people, with figures pausing and photographing underneath.

Why This Project Matters

Fair entrances are usually forgettable because they are designed as logistics. Umbral Floral shows that the approach can carry the event's ideas before anyone walks into a show room. A threshold does not have to be a gate; it can be a stretch of path that changes your pace and attention.

The project also makes a practical case for bamboo in temporary urban structures: light, quick to assemble with bolts and rope, and adaptable enough to fit around trees that a heavier system would have threatened. At 120 m², it is a small piece of work, but it fits its site and its purpose closely, and that precision is worth more than a larger showpiece.
