The architecture of the Sarkhej Roza is done by Azam and Muazzam Khan; two persian brothers. The complex was originally spread over 72 acres, surrounded by elaborate gardens on all sides. Over the time human,settlements come around it ,eating into the gardens and reducing the area 34 acres. Shaikh Ahmed Khattu Ganj Baksh f Anhilwad, Patan the friend of adviser of Ahmed Shah l, retired to Sarkhej in his later life and died here in 1445. In his honour a tomb, begun in 1445 by Muhammad shah ll ,was in 1451 ,finished by Qutbuddin Ahmed Shah ll. The next sultan Mahmud Begda was fond of the place and expanded the complex greatly . He dug a large Sarkhej lake,surrounded it with cut stone steps , builts on its south -west corner,a splendid palace,and finally , opposite to the Ganj Baksh's tomb, raised a mausoleum for himself and his family , where he his son Muzaffar shah ll and his queen Rajbai are buried.
