Grey Beard advises owners in South Delhi on selling or rebuilding houses of ₹10 crore and above.
The ten steps
From the first decision to your keys

01
Sell or build with a builder
Selling is money and closure; building takes 24 to 36 months.

02
Know what your plot allows
Height, protected monuments, Lutyens' Zone.

03
Know the numbers
Builders always work from the price of floors today.

04
Choose the floors you keep
The four floors for sale are not equal.

05
Choose the builder
Walk through his buildings that are five to ten years old.

06
The agreement
Your floors by name, the land share, who gets the Completion Certificate (CC).

07
The specification sheet
"Or equivalent" becomes "of the same range or higher quality".

08
Parking
The stilt plan decides your parking.

09
When the building is late
You pay the builder nothing; when he is late, he pays you.

10
A narrow power of attorney
Approvals and filings only.
The guide has the rest — the worked numbers, what the agreement and the specification sheet must say, how long it takes, and the checklist.

In detail
Rebuilding with a builder, in detail
Sell outright, or build with a builder?
Rebuilding your house with a builder is one of the biggest decisions a South Delhi owner will make. Get it right, and you unlock the full value of your plot. Get it wrong, and you face years of stress, poor construction, and a home that does not hold its value.
The answer depends on your circumstances, not just the numbers. In a collaboration, you give your plot and a builder builds on it, usually a new builder-floor building. You keep one or more floors (often the ground floor or the top floor with terrace), and the builder sells the other floors to cover his cost and profit. You pay the builder nothing.
The appeal is clear: a brand-new home on your own plot without spending on construction, while the builder's floors turn the unused building rights on your land into value. Done right, your floors plus what the builder pays you can be worth well more than an outright sale.
A full sale, on the other hand, gives you money, simplicity and closure. For owners who do not plan to live in the house, it is often the cleaner path. Building takes 24 to 36 months from signing to handover. We advise on both, and show you what your plot is worth each way.
Choosing the builder, colony by colony
This is where most owners make mistakes, and where the stakes are highest.
Colonies where few builders work to the standard expected: Jor Bagh, Shanti Niketan, Westend, Chanakya Puri, Vasant Vihar, Anand Niketan, Panchsheel Park, Defence Colony, Neeti Bagh, Anand Lok, SDA, Mayfair Garden, Gulmohar Park, Chirag Enclave, Friends Colony East and West, Maharani Bagh, Hauz Khas Enclave, Nizamuddin East and Ishwar Nagar. Here the pool of builders able to deliver what buyers expect is small. Buyers at ₹10 crore and above expect strong construction, fine finishes and reliable delivery. A builder who does well in one colony may not have the record for another. Work only with established builders who have built well in similar colonies. Ask to see finished buildings, not drawings or brochures, and talk to the owners they have worked with.
Colonies with many active builders: Greater Kailash 1 and 2, Safdarjung Enclave, Green Park, Saket, Chittaranjan Park, South Extension 2, GK Enclave 1 and 2, GK-3, Sarvapriya Vihar, Siri Fort Road, Pamposh Enclave, Hemkunt Colony, Navjeevan Vihar, Geetanjali Enclave, Kalindi Colony, Sarvodaya Enclave and Sukhdev Vihar. Here many builders compete for each plot, and the quality ranges from excellent to very poor. The number of choices can be paralysing. What works: walk through their older buildings, five to ten years old, not the newest ones. That is where you see how the construction holds up. Check the waterproofing, the plumbing, the common areas. Talk to the people living there.
And trust your instinct. You will spend 24 to 36 months working with this person. If something feels wrong during the negotiation, it will only get worse during construction. We help you find the right builder for your plot, your expectations and your temperament.
The agreement
Whatever the colony or the builder, strong paperwork is essential. Every collaboration needs a detailed agreement read by your own lawyer. The best builder-owner relationships are the ones where the paperwork is so thorough that neither side ever needs to look at it.
It must set out: exactly what is built (the number of floors, the covered area, the specification); the handover date, with a penalty for delay; the materials and finishes, in writing, not spoken; which floors you keep and which the builder sells; who is responsible for approvals and permissions; and how disputes are settled.
Our role: we advise on the commercial terms, help you compare builders' offers, and make sure the deal protects you.
Reading the specification sheet
Every builder gives you a specification sheet. It is the single most important document in a collaboration: it defines exactly what you get. Most owners skim it. That is a mistake.
Where builders cap the cost. Marble flooring is usually quoted at a rate per sq ft; if you want better slabs, agree a higher cap or an upgrade clause with a clear way of paying the difference. The kitchen budget, appliances included, covers a basic setup; for better built-in brands, agree a higher cap or pay the difference. Bathroom fittings have a cap per floor for brands like Grohe, Kohler or Vitra, enough for basic ranges but not the higher ones or rain showers. Wardrobes have a cap per floor; check whether it includes the fittings inside or only the frame. The cap for decorative lighting is often surprisingly low, basic fixtures only. Hardware (locks and handles, brands like Hettich, Blum, Ipsa or Dorset) has a cap per floor, enough for standard ranges only.
"Or equivalent". Watch for wording like "JK Lakshmi cement or equivalent", "Nutech concrete or similar", or "Schneider/Siemens/Legrand" switches. "Or equivalent" lets the builder use cheaper alternatives. Where a brand matters to you, name it in the agreement and remove "or equivalent" for the key items. Since some products do get discontinued during a build, the fair wording is "of the same range or higher quality", not just "equivalent". The difference matters for electrical fittings, plumbing and finishes, where the gap between ranges is large.
What is not in the sheet often matters more: the ceiling height, which should be the same on every floor, not just the show floor (in South Delhi, 10 feet or more is good; less is a compromise); backup power, and its capacity; the driveway, boundary wall, garden and outside lights; who pays for approvals and municipal fees; how long the builder stays responsible for defects after handover; the waterproofing warranty (ten years at least); who gets the Completion Certificate (CC); and the parking: the stilt plan, the number of slots, and gate access.
Good signs in a specification: earthquake design to Zone IV or higher (Zone IV is the legal minimum for Delhi, so ask whether the design goes beyond it); ready-mix concrete from known companies, not mixed on site; named brands for steel (Rathi FE-500D), cement (JK Lakshmi, UltraTech) and pipes (Astral, Supreme); separate water tanks and pumps for each floor; well-known lift brands (Schindler, Otis, Kone) with an automatic rescue device; VRV or VRF air conditioning (Daikin, Mitsubishi) rather than split units; rainwater harvesting; and a written waterproofing method for the terrace (Tapecrete, Dr. Fixit and fibreglass mesh).
Parking
Parking is one of the most argued-over parts of any collaboration, and one of the most overlooked in the negotiation. In a four-floor building, parking is limited and every good slot matters.
The number of slots for each floor: have it written in the agreement, not left to the stilt plan. Where your slots are: not all slots are equal; slots at the front, near the gate or the lift, are far easier. Make sure yours are good ones, not whatever is left after the builder's floors are served. Your own gate: if the stilt plan allows a separate gate for your floor, ask for it. Visitor parking: is there any, and who controls it? The stilt plan: attach it to the agreement, with your slots clearly marked and signed by both sides. Spoken promises about parking mean nothing.
Protected monuments (ASI)
If your house is in Mayfair Garden, Nizamuddin East, Sarvapriya Vihar, or any colony near a monument protected by the ASI, the picture changes a great deal.
Within 100 metres of the monument, no construction is allowed: no building, no rebuilding, no demolition. A house here can only be renovated, and the covered area cannot grow. Between 100 and 300 metres, building is possible with ASI permission, which adds time and uncertainty. Many builders avoid these zones; the ones who work here need experience with the approvals.
For a seller, telling buyers the ASI position accurately is essential. For a buyer, checking exactly where the house sits from the monument, and so which zone it falls in, comes before any commitment.
Lutyens' Zone
If your house is in Golf Links or Sunder Nagar, the usual collaboration does not apply. These colonies are in the Lutyens' Zone, where new builder floors cannot be built. You can rebuild, but only to the covered area that exists today, so houses with a larger existing covered area sell for much more, and those with less sell for less.
A very small number of older builder floors exist here, built before the rules came in. There will be no more of them. Builders do not buy in this zone; homes are bought to live in. If you are thinking of rebuilding, we advise on the rules and introduce architects and contractors who have built in the Lutyens' Zone.
The clauses that matter most
A collaboration agreement usually runs to more than thirty clauses. Most owners focus on the obvious ones; the ones that matter most are the ones you do not think to ask about.
Which floors you keep. Far more than "you get the first floor": the land share of each floor, the parking with its own gate, the use of common areas, and who owns the terrace. Each one affects resale for years.
Payments to you, if any, are tied to stages of the build: the roof, the floors, the handover. What counts as each stage, how it is checked, and what happens when the builder misses it are all negotiable. Most owners accept the builder's first draft without knowing how much room there is.
Defects. Standard agreements often cover only twelve months, too short for waterproofing and structural problems that can appear years later. Push for longer.
Delay. In many agreements the penalty for delay is small next to the value of the property: ₹2–3 lakh a month on a building worth ₹30 crore or more is no deterrent. It needs teeth. You pay the builder nothing; when he is late, he pays you.
The power of attorney. A narrow power of attorney for the builder to handle approvals and filings is normal and needed. It must not let him sell or transfer your share of the land, or create any debt in your name beyond what is written. Have your lawyer draw its limits tightly.
Sub-contractors. The builder will use them; that is normal. The agreement should keep full responsibility for quality, specification and timing on the builder, whoever he appoints.
The terrace, changes to the front of the building, upkeep of common areas, and the transfer clauses all matter long after the build: to your resale value, your legal position and your daily life.
Despite all the paperwork, the most important thing is who you are dealing with. A good, fair businessman will honour the agreement in spirit, not just in letter. A dishonest one will find ways to trouble you whatever is written. No clause replaces character, which is why we spend as much time on the builder as on the agreement. We have read hundreds of these agreements, and know what is standard, what is negotiable and what is missing.
The numbers, and the land share
The cost is not just construction. It starts with the plot, then stamp duty and registration, the cost of building, and the builder's return. A builder needs a margin of at least 20 per cent for the arrangement to work. Builders always work from what floors sell for today.
The four floors for sale do not have the same value. Basement plus ground, the middle floors, and the top floor with terrace sit at different points on the price ladder.
A common land share is 22.5% for each floor, 10% for the basement, 32.5% for basement plus ground, and 45% for a duplex. These are working patterns, not a substitute for the deed: the deed and the agreement decide the rights that pass with each floor. Stilt parking, terrace and basement rights need the same care: allotted, exclusive or common.
Four colonies
Vasant Vihar: plots from about 250 to 2,000 square yards. Larger plots and a builder with a proven record are central to a workable collaboration.
Defence Colony: typical plots of 217, 325, 333 and 900 square yards. The road width, the frontage and the block decide what makes commercial sense.
Greater Kailash: plots from about 208 square yards upward, with many builders competing. Compare the block, the frontage and the builder's record rather than treating the area as one market.
Panchsheel Park: typical plots of 270, 500, 800 and 1,200 square yards. The builder's quality, which floors you keep, and the final documents matter more than any general promise.
Master Plan 2047, and regularisation
Master Plan 2047, notified on 20 August 2026, sets the height for plotted housing at 17.5 metres with a stilt. It is not a general right to an extra floor. Have your own plot's position checked in writing before you act.
Greater Kailash, Panchsheel Park, Defence Colony, Vasant Vihar and Maharani Bagh are not unauthorised colonies, so the regularisation scheme never applied to them; they are not on the DDA list of 69 affluent unauthorised colonies. That does not remove the need to check the title, the building plan, the road, any heritage rule and the approvals for a particular house.
Questions
What people ask
Should I sell the plot or rebuild with a builder?
Selling is money and closure. Building with a builder gives you new floors on the same plot, but takes 24 to 36 months. Get a price for selling the plot outright first, then compare it with what you would keep.
Who pays the builder?
You pay the builder nothing. You give the plot; the builder pays for the building, keeps some floors and sells them, and you keep the rest. If the building is late, he pays you a penalty for every month.
How is land share decided?
The deed for that building decides. A common pattern is 22.5% for each floor, 10% for the basement, 32.5% for basement plus ground, and 45% for a duplex. Write the land share of each floor, and who gets which floor, by name.
Who owns the parking after rebuilding?
The stilt plan decides it. The agreement should say how many slots each floor gets and which ones, with the stilt plan signed and attached.
What should I check before signing with a builder?
Walk through his buildings that are five to ten years old and talk to the owners living there. Then the agreement: your floors by name, the land share, what is built, the handover date and the cost of delay, who pays for approvals, who gets the Completion Certificate (CC), and the specification sheet attached. Have your own lawyer read it, not the builder's.
How long does rebuilding take?
Allow 24 to 36 months from signing to handover. Approvals usually take one to three months; five at the outer end.
Does Master Plan 2047 give me an extra floor?
No. It sets 17.5 metres with a stilt for plotted housing. It is not a right to an extra floor on every plot. Get your own plot's position checked in writing.
Take independent legal and tax advice before you sign with a builder.
