Our proposal for the Triumph Pavilion 2019: “Light” looks at the opportunity for the structural system to create dramatic and interesting lighting conditions. Walking through the pavilion, light and shadow dance dramatically, playing off the natural materials and the lush surroundings. When sunlight hits the pavilion’s serpentine, double-layered structure, it creates a variety of unique and dynamic patterns in both light and shadow. The structure provides a respite from direct exposure and depending on the time of day and the season, the areas of shade and sun differ.
The pavilion is constructed completely of laminated timber products. The floor and ceiling are composed of cross-laminated timber (CLT) panels, and the vertical and diagonal structural system is a series of glulam timber members. These materials are recently making a strong comeback within the architectural and fabrication industries. Laminated timber products are a sustainable and renewable resource. The density of wood is a fifth that of concrete, allowing for milled openings and connections to be prefabricated off-site. In addition, these CLT and glulam members can be exposed visually without the need for cladding. The CLT floor and ceiling panels for this pavilion take advantage of common CNC milling to produce an innovative structural system that employs prefabricated notches, and will arrive on site fully ready to accept the glulam members. This allows for a quick and easy assembly, and disassembly process. We’ve fully tested and engineered the structural system using structural analysis software (see diagrams below) and confirmed that the system is stable, with the vast majority of the members acting in compression and overall system deflections of less than 1mm.
The form of the 96 sqm pavilion strategically responds to the Museum Gardens and the surrounding buildings. The pavilion creates an interesting route through the landscape, working its way back and forth providing a variety of lighting conditions with patterned patches of light changing hour by hour, each day. The pavilion’s entry and exit faces the park entrance to the northeast, and the Church of St. John to the southwest. Along this circulation route, visitors can either circulate through the pavilion or take advantage of the various seating areas to relax and contemplate in solitude, or gather in small groups to share discussions with friends and other visitors.
