Diwanji ni haveli is one of its kind wooden haveli. The structure is 4 floors with large floor areas. The major challenge was the levels around wooden joints had dropped due to decay of the joint. All joints had to be repaired and levels restored.

A major exercise of unloading the heavy floor base (fuska floor) and to be replaced with lighter material and also ensure the required stiffness of floor was done using approved methods from European restoration industry. The other major intervention was use of alternative floor base instead of wood to reduce cost and also solution for termite free material. All artisans for lime, stone and woodcarving worked to recreate the original designs.
