Jesús Vassallo creates mass-timber pavilion for bird watchers

Architect Jesús V،allo and a team of graduate students at Rice University have added a pavilion made of cross-laminated timber panels to the Houston campus.

The Johnson Owl Deck Pavilion was constructed using cross-laminated timber (CLT) panels to demonstrate the material’s ،ential as a carbon-negative and sustainable building met،d while serving a specific function.

“We wanted to design a building that would be true to CLT’s structural behaviour and aesthetic ،ential,” said V،allo.

“No،ays m، timber buildings are increasingly normative and based on repe،ive grids that while efficient from an economic standpoint, do not do justice to the versatility of the material.”

The structure is located in the university’s Harris Gully Natural Area, a restored watershed that attracts a high level of bird species to the campus.

At 1,000 square feet (92 square metres), the pavilion contains eight rectangular columns topped with a single square, flat roof. It has an uncomplicated appearance by design.

The structure’s columns and roof were made of CLT panels of southern yellow pine in their “purest” form to s،wcase the material’s ،embly.

Each column was rotated at a different angle to provide privacy for bird watchers or other visitors to the pavilion.

“From the inside, the variable angles work as a sort of camouflage,” said V،allo. “Creating patterns of light and shadow, minimizing the presence of the people using the pavilion to do bird wat،g.”

“From the outside, the effect is that of a building that is constantly changing as you walk around it.”

According to the team, the pavilion was designed to look like the “ruin of a small temple” a، the plant life of its site.

It marks the beginning of a long-term plan to manage the microhabitats of the area, which includes shrubland, woodland, marsh, and prairie.

The structure was created in a m، timber seminar led by V،allo and designed with graduate students Pouya Khadem and Lene Sollie and structural engineer T، Huynh.

The pavilion is a permanent installation on the campus and can be visited by students and the public alike. Other timber pavilions include one in Montana by CLB Architects that used a similar configuration to promote the material.
