Dian Istana Group is a leading property developer in Surabaya with over 40 years of experiences.
We started off as one of the first developer in Surabaya, when in 1972, we established PT. Bumi Indah Jaya with residential projects in Dharmahusada Indah and Kertajaya Indah. Since then, our companies and its subsidiaries have substantial interests in real estate, commercial, and other property developments throughout Indonesia.
A thoughtfully scaled residential community for those who value privacy, convenience, and a more personal sense of place. Here, you are close to everything that matters—leading schools, shopping malls, dining, and the city’s key destinations—yet comfortably removed from the traffic, noise, and density of larger developments. Its intimate scale creates a sense of exclusivity that is increasingly rare: fewer homes, a more established neighbourhood, and everyday living that feels effortless. Rather than paying for the scale and spectacle of a “big developer” township, Dian Istana focuses on what truly adds value to your life—an exceptional location, generous living, and a home that offers more for what you invest.
