The Timber Pavilion is located in Porvoo, Finland, a city known for its wooden architecture and rich history. This pavilion offers a modern space that connects with the surrounding environment while honoring the city's architectural past. The design aims to create interactions between people and nature, incorporating materials that emphasize sustainability.

Structural Integrity and Design

Timber roof trusses form the fundamental structure of the pavilion. These trusses have been in use since the Middle Ages and are designed in a triangular shape. This shape enhances strength by reducing bending stresses at the joints. The addition of purlins provides extra support to the rafters, contributing to the overall durability of the building.

Material Selection

A key feature of the pavilion is the use of transparent wood composites that are filled with polyvinyl alcohol (PVA). This unique material offers low thermal conductivity and high light transmittance, allowing for better energy efficiency compared to traditional glass. The strength and hardness of transparent wood enhance the structural stability of the pavilion while adding visual interest.

Lattice Framework

The pavilion showcases a distinctive lattice structure, which is well-suited to the characteristics of transparent wood. This design choice not only serves a structural purpose but also creates an appealing visual effect on the exterior. To further strengthen the framework, a recycled polymer is used in place of lignin. This combination ensures that the building is both robust and functional, while also aligning with sustainable design principles.

Interaction with Natural Light

The design promotes a strong connection with nature by allowing natural light to fill the interior spaces. Large openings and the arrangement of the lattice structure invite daylight while creating changing patterns throughout the day. This connection to the outdoor environment enhances the experience within the pavilion, making it a welcoming space that encourages visitors to engage with the landscape. The interplay of light and shadow adds complexity and warmth to the interior, highlighting the beauty of simple, everyday materials and design.
