Downtown Houston is testing a set of shade pavilions shaped like petals. These pavilions sit on sidewalks, carry lights and hold planting beds. The landscape architecture firm SWA designed the kit to make walking downtown more comfortable in the heat.
The project, called Cool & Connected Corridors, retrofits existing streets with cooling infrastructure. Each element can be deployed in different places, and it adapts to the sidewalk conditions already there.
The effort is part of the city’s wider Public Realm Action Plan. The city says the goal is to make Downtown streets “more delightful, comfortable and easy.” Downtown Houston+ led the plan, which was developed with the urban strategy team Gehl, Agora Partners and Outside Voices.
Phase 1 covers a 15-block stretch of Texas Avenue. Crews installed them there ahead of the 2026 FIFA World Cup.
The toolkit behind the houston cooling pavilions
SWA principal Natalia Beard describes the work as a blueprint. “Cool & Connected Corridors is a blueprint for taking action here and now,” she said, adding that cities can layer social, economic and environmental benefits in a cost-efficient way.
The toolkit has three main parts. A lighting system improves visibility and safety at night. Modular planting beds hold drought-tolerant, pollinator-supportive plants. Mesh pavilions, designed by the architecture studio Höweler + Yoon, provide the shade.
Pavilions can also frame a landscape for quiet observation, and this curved design shows how form shapes that experience. Cylindrical Wildlife Viewing Pavilions in Upstate New York offers another take on shelter built around people and nature.
Each pavilion is made of bead-blasted stainless steel. Mesh membranes shift through gradients of blue, green and purple. The petal-shaped canopies stretch overhead to shade street corners during the day, and integrated lighting makes them glow after dark.
The team designed each pavilion to stand alone or to cluster with others into “bouquets.” Meejin Yoon, co-founder of Höweler + Yoon, sees the arrangement as a wayfinding tool. “Together, they create a sequence of shaded landmarks that help orient pedestrians from block to block,” she said.
Globe-shaped and line-form lights hang down from the tree canopy. The city’s 2023 lighting study shaped the houston streetscape design. That study mapped a master plan for lighting the nighttime streetscape.
The system also includes wayfinding, replacement trees and planters stocked with drought-tolerant, pollinator-supportive species.
Early readings
SWA reports thermal infrared readings of ground surfaces beneath the pavilions. The readings show an average temperature drop of 10°F (5°C). In some spots, the drop reaches 30°F (16°C).
Next, the city plans to extend the system along the rest of Texas Avenue. The Public Realm Action Plan also names McKinney Street and Preston Street as priority corridors for the same treatment. Those streets are part of the plan’s first set of Downtown projects for 2025, which also calls for daily programming in parks and a review of underground tunnels that link downtown office buildings.
Extending the system also raises bigger questions about how cities balance growth with historic places. Tower of London Threatened by City Plan 2040 shows how planning decisions can reshape a city’s most protected landmarks.
Engagement shaped the plan. Two open houses gathered more than 700 points of feedback. More than 40 stakeholders worked through over 12 hours of workshops. Researchers logged 16 hours of public life observations to track how people move through Downtown.
Downtown’s streets are the next test. If the shade readings hold on McKinney and Preston, the toolkit could become a template for other blocks.

Frequently asked questions
What is the Cool & Connected Corridors project in Houston?
Cool & Connected Corridors is a project by the landscape architecture firm SWA that retrofits existing downtown Houston streets with cooling infrastructure. It is meant to make walking downtown more comfortable in the heat, and it is part of the city’s wider Public Realm Action Plan.
What three main parts make up the Houston cooling toolkit?
The toolkit has three main parts: a lighting system that improves visibility and safety at night, modular planting beds with drought-tolerant and pollinator-supportive plants, and mesh pavilions that provide shade. The mesh pavilions were designed by the architecture studio Höweler + Yoon.
How much cooler are the ground surfaces under the Houston pavilions?
SWA’s thermal infrared readings show an average ground-surface temperature drop of 10°F (5°C) beneath the pavilions. In some spots, the drop reaches 30°F (16°C).
Which Houston streets will get the cooling pavilions next?
The city plans to extend the system along the rest of Texas Avenue, where Phase 1 covers a 15-block stretch. The Public Realm Action Plan also names McKinney Street and Preston Street as priority corridors for the same treatment.
