Locality Guide · South Delhi
A prime, tightly-held colony wrapped around one of Delhi’s great high-street markets — lettered blocks of stilt-plus-four builder floors on the Ring Road, its own metro station, a short hop from AIIMS, Lajpat Nagar and Defence Colony.
Property in South Extension Part II trades at roughly ₹25,000–37,000 per square foot for builder floors — putting a typical 4 BHK floor between ₹9 and ₹16 crore, with smaller or older resale floors starting below that and the largest, market-facing floors ranging well above.
We have spent four decades closing floor transactions across South Delhi from our base in Defence Colony, next door, and in a colony like this the gap between a good buy and an expensive one is rarely the finish. It is the plot, the block and the paperwork — and, in South Extension, whether the address is residential or brushes the commercial frontage. This guide lays out what property in South Extension Part II actually costs, how its blocks differ, what it rents for, and the checks that protect a buyer before a single rupee moves.
South Extension is unusual among South Delhi colonies: its market is one of the most valuable high streets in India, and that commercial pull sits right against the residential blocks. It keeps values firm and demand deep, but it also means a buyer must read the exact block and lane — a purely residential inner plot and a plot near the market frontage are very different assets, with different rules, buyers and paperwork.
At a glance
Indicative levels for new or near-new construction. Actual pricing swings with plot size, block, floor and how close the plot sits to the market frontage. Values reflect current market data for South Extension and should be confirmed against the specific floor.
This is the minimum registration value of the land, not its market price — for a built property you add the cost of construction. Circle-rate categories vary within the South Extension pincode, so confirm the exact category for the specific plot before you budget. See Delhi circle rates in full →
How it formed
South Extension — formally New Delhi South Extension, “South Ex” to everyone who lives near it — is a planned post-Independence colony carved out of the old Kotla Mubarakpur lands, laid out along the Ring Road just east of AIIMS and organised as two parts. Part II is the larger residential half, arranged in lettered blocks around a celebrated shopping street, with its own market, a primary school, parks and, since the Pink Line arrived, a metro station of its own.
As across South Delhi, the original plotted houses have redeveloped one plot at a time into stilt-plus-four builder floors — several homes on each old address — so with no vacant land and no apartment towers, new supply is entirely redevelopment-driven. What sets South Extension apart is the market: one of the most valuable high streets in the country runs through it, which keeps demand deep and values firm, and gives the colony a mixed residential-and-retail character no purely residential enclave has.
A typical stilt-plus-four redevelopment — several floors on one plot.
Where value lives
South Extension Part II is best read as a ring of lettered blocks around a central market and school, with the Ring Road and the metro along the northern edge. Plots run from about 200 to 500 square yards, so where a floor sits — and how close it is to the market frontage — moves price more than fittings do. The northern blocks face the Ring Road and the South Extension market and metro: the most connected, highest-footfall edge. The central blocks (around the primary school and the colony’s parks) are the quiet residential core. The eastern blocks lean toward Lajpat Nagar and the metro station; the western and southern blocks run toward AIIMS and the calmer inner lanes. Purely residential inner plots and plots near the commercial frontage are different assets — different buyers, rules and paperwork.
Which block suits you is really a plot-size, orientation and use call. The finer nuances — which lanes are quietest, which titles are cleanest, which plots sit far enough from the market to stay purely residential — are exactly what we walk clients through before they shortlist. Tap the map below to see how the colony is laid out.
Each gold area is one part of the colony — the Ring Road and market frontage to the north, the school-and-park residential core in the centre, the Lajpat Nagar side to the east and the AIIMS side to the west — wrapped by the Ring Road, Lajpat Nagar, Kotla Mubarakpur and the AIIMS edge. Tap an area for its character. Schematic overlay — not to scale.
Colours mark each part of the colony; plot size (about 200–500 sq yd) and distance from the market frontage move price here more than finish. Landmarks and boundary roads are for orientation; the overlay is schematic, not to scale.
Ask us about this area →Three ways to buy
The cleanest option. You inspect the finished product and get fresh construction with a builder warranty. You pay the top rate — toward ₹37,000 per sq ft, more for a large or well-placed plot — for it.
Typically 15–30% cheaper per sq ft, which is why sound resale floors here start well below new build. The land share is identical, so the discount sits on structure and fittings — often the best value in the colony.
Milestone-linked payments and a modest price edge, against completion risk. Most single-plot redevelopments fall below Delhi’s RERA thresholds — your protection is the builder’s record and your agreement.
Daily life
The appeal here is a rare mix of central-Delhi convenience and settled colony life. South Extension Part II reads as a low-rise, low-density enclave — no towers, no tower committees — but with one of the city’s great shopping streets running through it. The South Extension market covers everything from flagship fashion to daily needs; a primary school and several parks sit inside the colony; and Lajpat Nagar’s Central Market is minutes away.
Everything sits within a short drive. AIIMS and Safdarjung hospitals are barely two kilometres west; Dyal Singh, PGDAV and Lady Shri Ram colleges and NIFT are close by; and Khan Market, India Habitat Centre and central Delhi are a short run up the Ring Road. On connectivity, South Extension’s own station on the Delhi Metro Pink Line sits on the northern edge, with Lajpat Nagar (Pink and Violet interchange) and INA a short hop away, and the Ring Road giving fast access to the airport, Gurugram and the centre. The honest trade-offs: the market draws heavy footfall and traffic, and parking near the commercial frontage can be tight.
What it earns
Rents in South Extension Part II are strong because the floors are large, the location is central and the tenant pool is deep — corporate leases, professional families, and demand spilling over from the market and nearby offices. A typical 4 BHK floor lets for roughly ₹1.5–3.5 lakh a month depending on plot size, block, floor and finish, with larger fully-furnished floors going higher. As across land-heavy South Delhi, gross yields are modest — on the order of 2–3% — because buyers here are paying for land, location and a landmark address, not cashflow.
The money mechanics
Circle-rate categories vary within the South Extension pincode, so the first step is to confirm the exact category for the specific plot with the jurisdictional Sub-Registrar — it sets the minimum registration value, with construction valued separately. Market values run several times the circle figure, and because Delhi charges stamp duty on the higher of transaction value or circle value, in South Extension duty is effectively paid on the actual deal price. On a ₹12 crore floor registered in a male buyer’s name, budget roughly ₹96 lakh stamp duty (8%), ₹12 lakh registration (1%), and 1% TDS deducted against the seller’s PAN. Registering in a female family member’s name brings stamp duty to 5% — a legitimate ₹36 lakh saving at this ticket. Banks typically fund 65–75% of a floor at this size, so plan your equity accordingly.

Protect yourself
In South Extension, the problems that surface later usually trace to two things: a plot near the market frontage being treated as purely residential when its permitted use or category says otherwise, and a thin or unregistered collaboration agreement from the plot’s redevelopment. Trace the full chain — original owner, collaborating builder, and every floor sold since — confirm the exact block, sanctioned use and circle-rate category, and price the land share, not the finish.
What typically trades
South Extension is tightly held, and the best floors move quickly and often off-market. These are indicative configurations and price bands, not live listings; the always-current list lives on our South Extension page, and we hold quiet floors matched to serious buyers.
Around 2,200–2,900 sq ft, stilt parking, lift and servant room — the South Extension workhorse.₹7–11 Cr
Around 3,200–4,000 sq ft on the larger plots — often corner, park-facing or on a wide road.₹12–20 Cr
Corporate and professional leases on the bigger floors.₹1.5–3.5 L/mo
How it compares
The two sit barely a kilometre apart and a buyer looking in one should look at the other. Defence Colony is the classic quiet, leafy, purely-residential address — lettered blocks around a central market and the covered nala, a settled old-money community and a clear circle-rate identity (Category B). South Extension Part II trades a little of that calm for one of the best high streets in the country on its doorstep, its own metro, and a mixed residential-and-retail character — often at a keener per-square-foot rate for a purely residential inner plot. Choose Defence Colony for a quieter, uniformly residential colony; choose South Extension Part II for connectivity, the market and metro at the door, and value on the right inner block. If a specific floor fits your brief better in one than the other that week, the floor usually wins — the colony-level difference is smaller than the plot-level one.

The medium term
Three things underpin the case. Supply is structurally scarce — a compact, fully-built colony with no vacant land, redevelopment-only, and few floors trading in any month — so scarcity here is permanent rather than cyclical. The market is a durable demand anchor: one of India’s most valuable high streets running through the colony keeps footfall, rents and interest permanently elevated in a way no purely residential enclave can match. And the fundamentals of daily life — a landmark market, a metro on the edge, top hospitals and colleges nearby and fast Ring Road access — are exactly what keeps a colony liveable and desirable decade after decade. None of this guarantees any single year’s return, but scarce, tightly-held land beside a landmark market with its own metro is a strong floor under value.
