Greenhouse, Botanical Garden, Zurich
The domes of the tropical houses dating from 1997—the botanical garden’s well-known landmark—had lost much of their light transmission, which impaired plant growth. This, along with other age-related deterioration of the buildings and building services, made a comprehensive renewal necessary.
Renewal of the dome greenhouses, Botanical Garden Zurich
Thanks to the use of “Structural Sealant Glazing”, the delicate dome structure made of slender aluminium tubes could be retained, preserving the distinctive character of the dome greenhouses. In addition, a horizontal ring prestressing system was installed, permanently relieving the existing embrittled aluminium cast nodes.
