Au Cosmos Corner Siddharth Vihar Flat Price 2026: Complete Price List, Sizes & Review

Siddharth Vihar in Ghaziabad has quietly become one of the most talked-about residential corridors in the Delhi NCR region, and the recent launch of Au Cosmos Corner has only added to the buzz. If you are searching for the Au Cosmos Corner Siddharth Vihar flat price, unit sizes, or whether this project is worth your investment, this guide breaks down everything you need to know in one place.

What is Au Cosmos Corner Siddharth Vihar?

Cosmos Corner is a new residential project by AU Real Estate, developed through its subsidiary Cosmos REIT Private Limited. The company secured the land parcel through a competitive auction conducted by the Uttar Pradesh Awas Vikas Parishad, at a transaction value running into hundreds of crores. The project sits on roughly 5.6 acres within the larger 700-acre Siddharth Vihar township, and it is built around three high-rise towers named Jagannath, Balabhadra, and Subhadra — names drawn from Puri’s Jagannath Temple tradition.

What makes the project stand out on paper is its design philosophy. Every apartment has been planned as a corner unit with a cross or plus-shaped tower layout, meaning each home opens on two sides. This is meant to maximise natural light and cross-ventilation, something that’s hard to find in typical NCR apartment blocks where units are packed side by side. Each residence also comes with an approximately 8-feet-wide sundeck-style balcony, which the developer is positioning as a signature feature rather than a standard afterthought balcony.

Au Cosmos Corner Siddharth Vihar Flat Price List (Latest Update)

The Au Cosmos Corner Siddharth Vihar flat price starts at an introductory base rate of around ₹6,900 per square foot. Based on this rate, the starting price for a flat works out to approximately ₹1.20 to ₹1.23 crore onwards, depending on the configuration and floor you choose.

Au Cosmos Corner Price List by Unit Size

Au Cosmos Corner 3 BHK Flats

• 1,780 sq ft: The entry-level configuration, ideal for nuclear families looking for a spacious three-bedroom home without stepping into the ultra-luxury bracket.
• 1,972 sq ft (3 BHK + Multipurpose Room): A slightly larger variant that adds a flexible extra room, useful as a home office, study, or guest space.
• 1,981 sq ft: A marginally bigger sibling of the base configuration, offering a touch more breathing room.

Au Cosmos Corner 5 BHK Flats

• 3,175 sq ft: The flagship offering, designed for larger families or buyers seeking an ultra-spacious home with six toilets and expansive layouts.

Additional Charges to Factor In

Keep in mind that the ₹6,900 per sq ft figure is the base rate quoted at pre-launch or launch stage. On top of the quoted Au Cosmos Corner flat price, buyers should budget for:

• External development charges (EDC)
• Car parking fees
• Club membership charges
• Preferential location charges (PLC) for higher floors or specific views
• GST and registration/stamp duty costs

These “other charges” typically add a meaningful percentage to the final quoted price, so it’s worth asking for a detailed cost sheet before booking.

Why Prices Are Positioned the Way They Are

Compared to neighbouring micro-markets like Noida Sector 62 or Indirapuram, where per-square-foot rates have climbed significantly over the past few years, Au Cosmos Corner’s pricing is being marketed as comparatively accessible for a project offering large-format homes and low-density planning. Each floor across the towers is limited to just seven apartments serviced by seven high-speed lifts — a deliberate choice to avoid the congested, high-density feel common in mega-townships.

Siddharth Vihar itself has seen strong property appreciation in recent years, driven largely by infrastructure upgrades. The area sits along NH-24, close to the Delhi–Meerut Expressway, and benefits from proximity to the Electronic City Metro Station and Noida Sector 62, both roughly five minutes away by road. The Hindon Elevated Road has also cut travel time between Siddharth Vihar, Raj Nagar Extension, and the Delhi border, while the Uttar Pradesh government has approved additional ramps on this stretch to further ease traffic between Vasundhara, Indirapuram, Kanawani, and UP Gate. These developments are frequently cited as reasons why analysts expect continued price appreciation in the corridor.

Amenities and Possession Timeline

Beyond the apartments themselves, Au Cosmos Corner offers a dedicated clubhouse spread across ground plus two floors, a swimming pool, a fully equipped gymnasium, landscaped green spaces, jogging tracks, children’s play areas, and round-the-clock security with controlled entry points. The project is RERA-registered, and the expected possession timeline has been indicated as being around 2031, which is fairly typical for a large-format, under-construction NCR project of this scale.

Should You Invest in Au Cosmos Corner Siddharth Vihar?

For homebuyers evaluating the Au Cosmos Corner Siddharth Vihar flat price, the project positions itself in what the developer calls the “aspirational luxury” segment — larger homes, better design, and improving connectivity, without the premium price tag of established Noida or Indirapuram addresses. That said, prices at this stage reflect an introductory or pre-launch rate, and such rates are almost always subject to upward revision as construction progresses and inventory sells.

Before booking, it’s advisable to verify the current price list directly with the developer or an authorised channel partner, confirm the RERA registration details, review the payment plan structure, and factor in all additional charges to arrive at the true out-of-pocket cost. As with any real estate investment, matching the project’s possession timeline and price trajectory with your own financial planning will help you make a well-informed decision.
