Dipoli

Dipoli is a convention center in Otaniemi with architecture that fits into the forest, featuring steep roof overhangs, copper cladding, wood surfaces, and massive boulder walls. The building holds over twenty conference rooms and auditoriums with movable walls that allow flexible space combinations for different events.

The building was constructed in 1966 as a student union facility for Helsinki University of Technology and served generations of students as a campus center. Following major renovations in 2017, it was transformed into Aalto University's main building and took on a new role.

The building uses natural materials like copper and wood that blend into the forest setting, giving the place its own distinctive character. The irregular shapes and how everything connects with the surroundings show a design philosophy that brings nature and architecture together.

The place is accessible but sits in a quiet forest setting on campus, so plan enough time to get there. The movable walls allow for different event sizes, so check beforehand which spaces are available for what you want to do.

Of the 500 windows in the building, only four share the same size, showing how carefully the architects designed each detail. These differences are a quiet testament to a commitment to architecture that adapts to nature rather than making everything uniform.
