Lasikupu

Lasikupu is a Finnish term that translates to "glass dome" or "glass bubble." It refers to a specific type of architectural feature, often seen in historic buildings, public spaces, and greenhouses. These structures are characterized by their transparent, curved roofs, typically made of glass panes held together by a metal framework. The design allows for maximum natural light penetration while providing shelter from the elements.

Historically, lasikupu designs emerged with advancements in glass manufacturing and metal construction techniques, allowing for larger and more complex curved shapes. They were particularly popular in the late 19th and early 20th centuries for conservatories, railway stations, and exhibition halls. The aesthetic appeal of a lasikupu lies in its lightness and the way it visually opens up the space beneath, creating an airy and bright atmosphere.

Modern interpretations of the lasikupu concept can be found in contemporary architecture, utilizing advanced materials like laminated glass and sophisticated engineering for enhanced durability and energy efficiency. While the term is Finnish, the architectural concept of domed or curved glass structures is a global phenomenon with variations in design and terminology across different cultures. These structures continue to be valued for their ability to blend indoor and outdoor environments and to create visually striking spaces.
