Drive south down Bannerghatta Road past the IIM Bangalore campus and the road narrows into Kalena Agrahara, one of those Bengaluru pockets that has quietly filled with mid-rise towers while the arterial road waited for its metro. It is here, on a 5.85-acre plot, that Sobha Limited is building Sobha Magnus, a 294-home project pitched at the 3 and 4 BHK buyer. With possession targeted for May 2030, the question for a buyer in mid-2026 is simple: is this a considered long-term home, or are you paying today for an address that arrives in four years?

The short answer. Sobha Magnus in Kothnur, off Bannerghatta Road, is a 5.85-acre development of 294 residences in 3 and 4 BHK formats sized 1856 to 2578 square feet, registered under K-RERA number PRM/KA/RERA/1251/310/PR/131025/008160 with possession set for May 2030. The case for it is Sobha's in-house construction reputation and a low-density layout; the trade-off is a long under-construction wait, a Bannerghatta Road corridor whose metro relief is still years out, and a premium South Bengaluru price point. Always confirm the K-RERA number and the live status on the official Karnataka RERA portal before paying anything.

This review walks through location, configuration, K-RERA status, pricing context and the honest trade-offs for a buyer evaluating Sobha Magnus.

Where is Sobha Magnus and what is the location trade-off?

Sobha Magnus sits at Kalena Agrahara, off Bannerghatta Main Road, in South Bengaluru, pin code 560076. The location's strength is access: Bannerghatta Road connects to the IT and hospital clusters of South and South-East Bengaluru, with established schools, malls and Apollo and Fortis hospitals nearby, and a developed social fabric rather than a greenfield gamble.

The trade-off is the corridor itself. Bannerghatta Road is one of Bengaluru's more congested arteries, and the Namma Metro extension meant to relieve it is still under construction along the stretch. So a buyer is betting on future metro connectivity that has not yet opened, while living with present-day traffic. That is a familiar South Bengaluru bargain, but it should be priced in, not assumed away. It also cuts two ways on resale: if the metro opens close to your possession in 2030, the connectivity premium could lift values just as you move in, but if it slips, you inherit the congestion without the upside. Treat the metro as a plausible bonus, not as a number already in your purchase price.

What does Sobha Magnus actually offer in configuration and density?

It is a low-density, larger-format project rather than a compact-unit one. Sobha Magnus spreads 294 residences across 5.85 acres, which works out to roughly 50 homes per acre, low by Bengaluru high-rise standards. The homes are 3 and 4 BHK units sized between 1856 and 2578 square feet, aimed squarely at upgraders and end-users rather than compact investors.

Listing material describes over 3.5 acres of open area including around 1.8 acres of landscaped zones, and a two-storey clubhouse cited at about 13,000 square feet, though buyers should treat the clubhouse size and the exact open-area split as developer and listing claims to confirm in the agreement and sanctioned plan. The substance worth verifying is the unit efficiency: ask for the carpet area against the super built-up area, because in larger Bengaluru units the loading factor materially changes what you actually use, a point we unpack in our carpet area versus super built-up area guide, linked below.

Is the K-RERA registration for Sobha Magnus genuine?

The project lists a K-RERA registration number, and it should still be verified by you. Sobha's official project page states the registration as PRM/KA/RERA/1251/310/PR/131025/008160, and the embedded date string points to a 13 October 2025 registration. The honest position for a buyer is that a number on a developer page is a starting point, not proof.

Before paying any booking amount, enter that exact number on the official Karnataka RERA portal at rera.karnataka.gov.in and confirm the project name, promoter, approved plan, sanctioned units and declared completion date match what you have been shown. Our step-by-step guide to verifying a K-RERA registration in Bengaluru, linked below, shows what each field should read. If any detail on the portal conflicts with the brochure, treat the brochure as wrong until reconciled in writing.

How does Sobha Magnus compare with other South Bengaluru options?

It competes on builder quality and format more than on price. The table below sets out the verified facts for Sobha Magnus and how each one should read for a buyer.

If you want a sense of how Sobha and peers are positioning newer South and East Bengaluru launches, compare the format and pricing logic against a township play like Sobha One World at Hoskote and a Bannerghatta Road peer such as Godrej Vanantara, both linked below. The contrast clarifies whether you are paying for low density, for a brand, or for a corridor.

What is the realistic pricing and value picture?

Sobha Magnus is a premium South Bengaluru product, and public listings place 3 BHK pricing in the region of a few crore rupees, but exact, current rates vary by tower, floor and offer, so treat any single quoted figure as indicative and insist on a written, all-inclusive price sheet. Sobha's appeal historically rests on its backward-integrated, in-house construction model, which many buyers value for finish quality and timeline discipline.

The value question is whether that premium is justified for your horizon. With possession in May 2030, you carry construction-period risk and your capital is committed for years before you can occupy or earn rent. If you need a home soon, a ready or near-ready project may serve you better. If you are a patient end-user who values a low-density Sobha-built address and can wait, the trade-off can make sense, provided the price sheet and the K-RERA record both check out. Remember too that a brand premium is only worth paying if it converts into delivery and finish quality you can verify; ask to see Sobha's recent completed projects in the same corridor, and weigh the actual handover record against the reputation rather than the marketing.

Who is Sobha Magnus right for, and who should look elsewhere?

It suits the patient, end-use buyer who wants a larger 3 or 4 BHK in a low-density South Bengaluru community and trusts the Sobha construction reputation enough to wait until 2030. For this buyer, the format, the open space and the established Bannerghatta Road social infrastructure are genuine positives.

It is a weaker fit for a short-horizon buyer or a yield-focused investor. The long possession timeline, the premium ticket size and the still-pending metro relief on Bannerghatta Road all cut against a quick return, and rental yields on large 3 and 4 BHK units in this belt tend to be thin relative to the capital locked in. Be honest about which buyer you are. The project is not flawed; it is simply a specific bet, large format, long wait, premium corridor, and it rewards only the buyer whose needs match that shape.

What is the K-RERA number for Sobha Magnus?

Sobha's official page lists the K-RERA registration as PRM/KA/RERA/1251/310/PR/131025/008160, with the number string indicating a 13 October 2025 registration. Always confirm this exact number on the official Karnataka RERA portal at rera.karnataka.gov.in, and match the promoter, plan and completion date there before paying any booking amount.

When is possession of Sobha Magnus expected?

Sobha's official listing gives a possession target of May 2030. That is a multi-year under-construction wait from a 2026 booking, so buyers carry construction-period risk and committed capital until then. Verify the completion date declared on the Karnataka RERA portal, since the RERA-declared date is the legally meaningful one for any delay claim.

What configurations and sizes does Sobha Magnus offer?

Sobha Magnus offers 3 and 4 BHK residences sized between 1856 and 2578 square feet, across 294 units on 5.85 acres. This is a larger-format, lower-density product aimed at end-users and upgraders rather than compact-unit investors. Ask for carpet area against super built-up area to understand the real usable space before you commit.

Is Bannerghatta Road a good location to buy in Bengaluru?

It offers developed social infrastructure, schools, malls and major hospitals, with good access to South and South-East Bengaluru job clusters. The trade-off is heavy traffic and a Namma Metro extension along the corridor that is still under construction. Buyers are partly betting on future metro connectivity that has not yet opened, so price that uncertainty in.

Sources worth reading in full: the official Sobha Magnus project page for configuration and the RERA number, and the Karnataka RERA portal to verify the registration yourself. For buyer process, see our guides to verifying a K-RERA registration in Bengaluru and carpet area versus super built-up area under RERA. To compare the project directly, see the Sobha Magnus listing, a township alternative at Sobha One World, Hoskote and a Bannerghatta Road peer in Godrej Vanantara.

Use this seven-point checklist before booking Sobha Magnus:

1. Enter the K-RERA number PRM/KA/RERA/1251/310/PR/131025/008160 on the Karnataka RERA portal and confirm every field.
2. Match the RERA-declared completion date against the May 2030 possession claim and the brochure.
3. Demand a written, all-inclusive price sheet specific to your tower, floor and unit.
4. Ask for carpet area against super built-up area to gauge the real usable space.
5. Confirm the clubhouse size and open-area split in the sanctioned plan, not just the brochure.
6. Check the Bannerghatta Road metro timeline so you do not overpay for connectivity that is years away.
7. Decide honestly whether your horizon fits a 2030 possession before committing capital.

Sobha Magnus is a credible, builder-backed, low-density home for the patient South Bengaluru end-user. The discipline a buyer owes themselves is to verify the K-RERA record live, read the carpet area, and accept that the May 2030 possession is the real price of this address.
