Because she was already a student of Ziyun class, she was assigned to a detached courtyard.
This courtyard was not as luxurious as Di Fuyi's. However, it was still a detached courtyard thus she could design it by herself.
In order to provide full facilities to the students, basically the courtyard that was assigned to the students was fully equipped and it looked like a studio in the modern day. However, anyone who had their own idea would redesign their interior.
According to the rule of Tianju Hall, as long as the exterior remained the same, the student could design the interior however they wished.
After all, if there was nothing unexpected that occurred, the students had to live at least eight to nine years in the same place. Therefore the students would put effort to redesign the interior as comfortable as possible.
Basically, all the interiors were designed based on their own preferences.
