Protection for plants and a café
Restoration work on the orangery began six years ago. The greenhouse originally served to protect sensitive plants from the harsh winters – a function that would have been an impossibility before renovation work commenced. Large areas of the orangery were in ruins and even in danger of collapsing. According to the plans for the restoration, the building was once again to be used to store plants in the winter, while it would house a café in the summer.
In structural design, an orangery represents an inventive cross between architecture as the human language of form and the free expression of nature. This idea has been realized in a limited space through the geometrically placed flowerbeds of the terrace and the orangery.
“Restover” meets all requirements
“The glasshouse of the orangery required a particularly careful renovation, restoration and preservation,” explains Anna Katharina Zülch, the Project Manager of the architects. The panes had to be put in the existing cast iron construction, which is why the glass could not be thicker than three millimeters. The temperature of the interior must be pleasant for café visitors, while at the same time serving the needs of the plants.
The architects chose “Restover” produced by SCHOTT Spezialglas AG, Standort Grünenplan because it meets the list of requirements. The panes are two and a half to three millimeters thick, have a slightly irregular surface and prevent annoying reflections. But most of all, the slight unevenness of the panes complies with the demands of the people who wish to preserve the authenticity of monuments: the new glass front creates the perfect historical appearance for the restored orangery.
