Rahim Abad Historical Complex includes fencing, guarded towers, garden, main building, basement, pebble mansion, stables and service spaces. In the three corners of the gardens, the remains of the towers are visible, and only the north-eastern tower of the building has completely disappeared through the construction of the mansion. The main axis of the garden is between the two mansions and in the longitudinal symmetry line.
This axis is distinguished with two ponds, a pool and trees along two sides of the route, which is a manifestation of the Iranian garden pattern.
Rahim Abad Garden of Birjand (Rahim Abad Mansion) is built in the north of the garden and in two floors and its ground floor is used with a number of rooms and corridors as service and storage spaces and no decorations.
The first floor of the Rahim Abad Mansion Building is a mirror hall with glued decorations including the role of the head of animals, flowers, plants, and various slahmi.
Considering the presence of the mirror room as well as the large other room on the eastern side of the building with a gypsum decoration, it can be seen that this section has been catering for guests and local people for the life of the ruler and his family.
The basin and its related buildings in the east and one bathroom and a number of rooms used as accommodation and warehouse are located on the southern side of the complex.
The building, which has gypsum decoration, can be seen that this section has been catering for guests and local people for the life of the ruler and his family.
Rahim Abad Garden and Mansion of Birjand is a valuable treasure of architectural adornment and has been registered in the 2707 National Register of National Monuments.
