Status: upcoming, not yet launched
Sunstream City is listed as an upcoming project. In May 2026, Hubtown's managing director said the Mulund-Thane project had not been launched. The company's Q1 FY27 review, held in early August 2026, placed Sunstream City among its upcoming projects, alongside other developments in the pipeline.
Management said the company expects a significant launch calendar for the second half of FY27, which runs from October 2026 to March 2027. The company has not given a specific launch date for Sunstream City within that calendar.
Developer and corporate background
The project is held by Sunstream City Private Limited, which was formerly known as Zeus Infrastructure Private Limited and was incorporated in Mumbai on 17 April 2006. Its directors are Rushank Vyomesh Shah, Chaitya Lalit Adani and Birendra Badri Prasad.
Hubtown was founded in 1985 by Vyomesh Mahipatray Shah and was earlier known as Ackruti City Limited. It has been listed on the NSE and BSE since 2007. For FY26, the company reported revenue of ₹833 crore and profit after tax of ₹168 crore. Its total borrowings were about ₹5,181 crore as of 30 June 2026.
Location and approvals
The registered address of the IT/ITES Special Economic Zone is in Village Mulund, near the EEH Mulund Tollnaka on the Eastern Express Highway. The developer describes the parcel as seafront land at Thane and Mulund. The government's operational SEZ list records the zone under Village Mulund, Taluka Kurla, District Mumbai Suburban.
Being listed as an operational SEZ is separate from the sale of residential units. As of May 2026, environmental clearances were still in process. Registration of residential sales under MahaRERA depends on those approvals and no registration number has been published for this project.
Scale of the land
Management has described Sunstream City as one of the largest land parcels in the Mumbai Metropolitan Region, with about 150 acres and roughly 2.5 crore sq ft of total area. Hubtown's FY26 summaries give a land area of about 141 acres and about 26.64 million sq ft of development potential. The gap between the two land figures reflects the different dates and bases of the disclosures.

Mulund is served by the Eastern Express Highway and the Mulund-Airoli bridge to Navi Mumbai. Mulund station is on the Central Railway line. Chhatrapati Shivaji International Airport is about 12 km from Mulund East.
Goregaon-Mulund Link Road (GMLR). The 12.2 km corridor will link the Western Express Highway at Goregaon with the Eastern Express Highway at Mulund. Its twin tunnels run 5.3 km between Dadasaheb Phalke Chitranagari and Amar Nagar. The first tunnel boring machine, Tulsi, was commissioned on 17 August 2026. The second machine, Vihar, was scheduled to begin excavation from 22 October 2026, subject to testing. The BMC targets completion around February 2029, after an earlier 2026 opening target was missed. The developers' projections for peak-hour travel between Goregaon and Mulund cut the trip from up to 90 minutes to about 25 minutes.
