Darulaman Realty Sdn Bhd (DRSB) was incorporated in 1981 to undertake the development of a new township in the District of Kubang Pasu in Kedah. The company purchased about 2,200 acres of estate land planted with rubber trees from Kundong Tanjung Pauh Company Bhd.

The company is responsible for the comprehensive development of Bandar Darulaman, a new "Satellite Township" in the district of Kubang Pasu, Darulaman Utama (Kuala Ketil) and Darulaman Perdana (Sungai Petani) Kedah Darul Aman.

DRSB commenced operations during the fourth quarter of 1983. The temporary campus of Universiti Utara Malaysia (UUM), then Malaysia's latest and its sixth university, was the curtain raiser. DRSB was both the developer and contractor for UUM with the first phase of construction completed by June 1984.

In 1995, DRSB has purchased 555.3 acres and 1,100 acres land in Sungai Petani (Darulaman Perdana) and Kuala Ketil (Darulaman Utama)
