The phrase "zur der sich die Laubengänge orientieren" appears to contain a grammatical error in the original text, as "zur der" is not correct German phrasing. However, based on the context provided, it seems that the intended meaning could be:

"Diese bekleiden vor allem die Straßenseite des Gebäudes, in Richtung der sich die Laubengänge erstrecken."

Translation: "These primarily cover the street side of the building, in the direction in which the arcades extend."

This rephrasing aims to capture the idea that the facade elements align with or face the direction in which the arcades are situated.

"Laubengänge" refers to arcades or covered walkways commonly found in architecture. These are typically open-sided corridors that are supported by columns or arches and often connect different sections or entrances of a building. Laubengänge are often seen in residential buildings, hotels, or other structures where covered walkways are desired for protection from the weather while allowing access to various parts of the building.
