Off Kanakapura Main Road, at Vajarahalli, Puravankara Limited is pre-launching a high-rise residential tower under the working name "Purva Codename Diamond." The same site, unit count and pricing also appear under the names Purva Hallmark and Purva Diamond Vajarahalli, so if you have seen more than one of these names in broker chats or ad creatives, you are not looking at competing projects, you are looking at the same pre-launch inventory marketed inconsistently before RERA registration locks in an official name. Here is an honest, early-stage look at what is known so far, and what still needs to be verified before anyone puts money down.
1. What's This Project Actually Called?
This is worth addressing before anything else, because it is the question we get asked most often about this listing. Pre-launch inventory in this belt is being marketed under at least three names: "Purva Codename Diamond" (a working codename used in some pre-launch marketing and broker outreach), "Purva Hallmark" (the name used in other marketing material for the identical site, acreage, unit count and pricing) and "Purva Diamond Vajarahalli" (also seen in some public listings). This kind of naming drift is common for projects that have not yet completed RERA registration, since the RERA-registered project name is often only finalised at or near formal launch. If you are researching this project independently, search all of these names, and confirm directly with the developer or their authorised channel partner which one will actually appear on the eventual RERA certificate before you rely on any single listing.
2. The Developer: Puravankara Limited
Puravankara Limited was founded in 1975 and has been listed on the NSE and BSE since 2007 (ticker: PURVA), one of Bengaluru's oldest and largest listed real estate developers, with operations spanning Bengaluru, Chennai, Hyderabad, Mumbai, Pune and more. The group operates through three brands: Puravankara (luxury), Provident Housing (mid-segment) and Purva Land (plotted developments). In FY2024 the group reported record annual sales bookings of ₹5,914 Crore, a 90% year-on-year increase. That listed, publicly-verifiable track record is a meaningfully different risk profile than a first-time or unlisted developer launching a pre-launch project under a codename, and it is one of the stronger points in this project's favour regardless of which name it eventually launches under.
3. Location: Vajarahalli, Kanakapura Main Road
The site (Sy No. 19/2) sits directly on Kanakapura Main Road (NH 948) in Vajarahalli, South Bengaluru. Key proximity points from the developer's location map:
- Thalaghattapura Metro Station (Green Line): ~280 metres, genuinely walkable
- Vajarahalli, Doddakallasandra, Konanakunte Cross, JP Nagar & Banashankari Metro Stations: along the same Green Line corridor
- NICE Road Junction: ~1.8 km
- D-Mart: ~0.8 km
- Forum South Mall: ~3.5 km
- Purva Zentech IT Park: nearby, Puravankara's own commercial/business park on the same stretch of Kanakapura Road
- Turahalli Forest: ~2.1 km, for green cover
This corridor has been one of the more consistently discussed growth belts in South Bengaluru over the past few years, largely because the Green Line metro extension turned a stretch of Kanakapura Road that used to be a long commute into something genuinely transit-connected. A site at ~280 metres from a functioning metro station is a rare, already-delivered advantage in a market where "upcoming metro" is often used loosely to describe infrastructure that is still years from completion. Purva Zentech, Puravankara's own IT/business park on this same stretch of road, adds a genuine end-user angle to a luxury tower like this one: buyers who work in that corridor, or who plan to lease to tenants who do, get a rare combination of a premium high-rise address and a short commute to a developer-backed office campus.
4. The Project: Scale and Configurations
Purva Codename Diamond is planned as high-rise towers (2 basements + ground + 29 floors) on approximately 3.6 acres, with around 250 residences, a genuinely low unit count for a tower of this height, which typically points to larger, more spacious floor plates per unit rather than the tightly-packed layouts common in higher-density high-rises. Two configurations are planned: a 3 BHK (Compact) at roughly 1,900 to 1,950 Sq.Ft, and a 3.5/4 BHK at roughly 2,100 to 2,250 Sq.Ft. Neither configuration has a confirmed unit-wise floor plan released publicly yet; the sizes above are the developer's own indicative range.
5. Pricing
| Configuration | Area | Approx. Starting Price |
|---|---|---|
| 3 BHK (Compact) | ~1,900-1,950 Sq.Ft | ~₹2.76 Cr* |
| 3.5 / 4 BHK | ~2,100-2,250 Sq.Ft | ~₹3.05 Cr* |
*Pre-launch/EOI pricing at a base rate of ~₹14,500 per Sq.Ft, as shared by the developer's marketing team. Subject to change at formal launch.
At ~₹14,500 per Sq.Ft, this pre-launch rate sits at the premium end for the broader Kanakapura Road corridor, reflecting both the metro-adjacent location and Puravankara's brand positioning. Pre-launch/EOI pricing is typically the lowest a project will see before formal launch premiums are added, and buyers who register interest early sometimes capture meaningfully better per-square-foot rates than buyers who wait for the formal launch. That upside has to be weighed against the added uncertainty of a project that has not yet secured RERA registration and is still circulating under more than one working name.
6. What's Still Unconfirmed
As with any pre-launch project, several things are not yet public, and this list applies whether you encountered the project as Purva Codename Diamond, Purva Hallmark, or Purva Diamond Vajarahalli:
- RERA registration: Not yet filed/approved as of this review. No RERA number exists yet; be wary of any listing that shows one.
- Final project name: Marketed variously as Purva Codename Diamond, Purva Hallmark, and Purva Diamond Vajarahalli.
- Detailed floor plans and tower elevations: Not yet released publicly.
- Final possession date: December 2031 is the developer's current indicative target, subject to change once RERA registration formalises the commitment.
7. Amenities (Planned)
The developer's current marketing material lists a multi-level clubhouse with indoor games, co-working spaces and event halls; a temperature-controlled swimming pool, gym, badminton and basketball courts, and jogging/cycling tracks; plus 24/7 3-tier security, video door phones, vehicle-free pedestrian zones, EV charging, solar lighting and rainwater harvesting. As with all pre-launch amenity lists, treat this as a plan rather than a guarantee until it is reflected in RERA-registered project documents, and confirm the final amenity list at the time of formal launch rather than relying solely on pre-launch collateral.
8. Frequently Asked Questions
Is Purva Codename Diamond a different project from Purva Hallmark?
No. Based on the identical site (Sy No. 19/2, Vajarahalli), acreage, unit count, configurations and pricing shared across both names' marketing material, this is the same pre-launch project marketed under two working names before RERA registration finalises an official one.
Which name should I use when I contact the developer?
Either name should reach the same sales team, since both point at the same site. When you do connect with them, ask them to confirm in writing which name the project will register under with Karnataka RERA, and get that confirmation before making any payment.
Is it safe to register interest before RERA registration is complete?
Registering interest to receive updates carries little risk, since it does not commit you to a purchase. Making a binding payment before RERA registration is confirmed is a different matter, and we recommend against it regardless of how attractive the pre-launch pricing looks.
Our Honest Assessment
Purva Codename Diamond's strongest, most durable selling point is genuine metro-adjacency, roughly 280 metres from Thalaghattapura Station is a rare, verifiable advantage that does not depend on future infrastructure delivery, unlike many "upcoming metro" pitches elsewhere in the city. Puravankara's listed, fifty-year track record also reduces, though does not eliminate, developer risk relative to smaller pre-launch players. That said, this remains an early-stage, non-RERA-registered listing marketed under at least three different names in the market: the project itself is still unsettled on branding, floor plans are not public, and pricing is EOI-stage rather than final. If you are evaluating this corridor, it is worth comparing against RERA-registered inventory like Aparna Wonder Woods before committing capital to a pre-launch position, and if you do proceed with Purva Codename Diamond, register interest to get updates, but hold off on any binding payment until RERA registration is confirmed and independently verified on the Karnataka RERA portal.
