People looking for luxury houses in Sector 21, Faridabad, usually want one of three things: a full kothi for the family, a newly built independent floor, or an older house they can tear down and rebuild. Sector 21 can offer all three, because it is a mature HSVP sector where large plots were sold to individual owners and many are now being redeveloped.
The sector is divided into 21A, 21B, 21C and 21D, on the western side of Faridabad close to the Aravalli ridge and the Badkhal side of the city. It has the settled feel that newer parts of Faridabad lack: grown trees, parks in front of houses and neighbours who have lived on the same street for years. It suits buyers who value a plotted address and are comfortable handling the paperwork that comes with HSVP land. It suits buyers who want amenities and a managed society less. This page focuses on houses and floors, with the checks that matter most for each.
The three ways people buy a house here
Most purchases in Sector 21 fall into one of three patterns. Knowing which one you are making shapes every later decision.
| What you buy | What you get | Paperwork focus |
|---|---|---|
| A complete kothi | Whole plot, all floors, full control | Original allotment, transfers, conveyance deed, plan |
| An independent floor | One level of a rebuilt building, shared land | Floor-wise sale deed, occupation certificate, parking |
| A house to rebuild | The plot, with demolition and construction ahead | Transfer papers, current building rules, architect’s review |
Buyers sometimes start looking for one and end up with another. A family who wanted a full kothi may decide two floors in the same building make more sense for parents and children. Stay open, but be clear about your priorities.
Kothis: what to inspect on site
An older kothi in Sector 21 can be a fine home, but age shows up in predictable places. On a visit, walk the house slowly and look at:
- dampness at the base of walls and under windows, which points to drainage or plumbing issues;
- cracks in beams, columns and roof slabs, especially on the top floor;
- the state of wiring, the main board and earthing;
- water tanks, pumps and the borewell, if there is one;
- rooms or floors that appear to have been added later.
Additions are the big one. Many older homes in Faridabad have extra rooms or covered terraces that were never on the approved plan. These can create problems when you sell, take a loan or apply for changes. Ask the seller to show you the sanctioned plan and compare it room by room with what stands.
Independent floors and collaboration deals
A large share of the newer supply in Sector 21 is independent floors. Usually, a plot owner has done a collaboration deal with a small builder: the owner hands over the old house, the builder rebuilds, and the two split the new floors. The builder then sells their share.
This model works well when the builder is competent and the paperwork is clean. It works badly when the agreements are vague. If you buy a floor, take these steps:
- Ask who built the building and visit one of their earlier completed projects.
- Read the collaboration agreement to understand who is responsible for defects.
- Confirm the occupation certificate covers your floor.
- Check that your sale deed states the floor, your share of land and your parking spot.
- Ask how the roof, stairwell, lift and water tanks will be shared and maintained.
- Get the details of any common maintenance arrangement in writing.
Haryana’s policy on how many floors can be built on residential plots has shifted in recent years. Ask, in writing, which permission your building was approved under, and have your lawyer confirm it.
Rebuilding an old house
Some of the most satisfying homes in Sector 21 belong to families who bought an old house and rebuilt it. You get a modern structure, your own layout and a mature neighbourhood. You also take on a long project.
Before you agree a price, get an architect to look at the plot and tell you what the current rules allow: coverage, setbacks, height, basement and number of floors. That decides what the plot is really worth to you. Factor in the time you will spend renting elsewhere, the cost of demolition and the risk of contractor delays. Many families find the payoff worth it, but only when they go in with realistic expectations.
HSVP paperwork in plain terms
Plots in Sector 21 come from HSVP, earlier known as HUDA. Every plot has a paper trail that starts with the original allotment and continues through each sale. The property is safest when every step of that trail is documented and recorded.
The core documents you or your lawyer should see include the allotment letter, each transfer or re-allotment letter, the conveyance deed, the sanctioned building plan, the occupation certificate and the latest tax receipts. Also check that there are no dues pending with HSVP or the Municipal Corporation of Faridabad, and that the property ID records match the seller’s name. If the house is being sold by heirs, make sure every legal heir has signed or released their share.
Value, street by street
In a sector like this, value depends far more on the specific plot than on the sector name. A park-facing house on a wide road with good parking will always hold value better than a similar house on a narrow lane facing the back of a market.
Things that support value include clean papers, a recent quality rebuild, lift access in a floor, good natural light and a calm street. Things that weaken it include disputed ownership, unapproved additions, poor drainage, heavy traffic past the gate and shared floors with unclear terms. Do not forget the costs on top of the price: stamp duty, registration, brokerage, interiors and any repairs before you move in.
Location inside the city also feeds into value. House hunters who drive to Gurugram tend to favour the parts of Sector 21 nearest the Aravalli road, while families with older parents often prefer streets within a quick drive of the Asian Institute of Medical Sciences in 21A. Delhi commuters look at how fast they can reach Mathura Road and the metro. Decide which of these matters most to your household, then judge each house against it.
Nearby options if Sector 21 is tight
Good houses in Sector 21 do not appear every week. If you need to move by a fixed date, it helps to look at neighbouring plotted sectors at the same time. Luxury houses in Sector 15 and the other older sectors in the same part of the city have similar housing stock and paperwork.
Some families also compare a plotted house with a premium apartment in a society. If you want that broader view, our page on luxury property in Sector 21 covers all formats together.

Frequently asked questions
What papers should I see before buying a kothi in Sector 21?
Ask for the original HSVP allotment letter, every subsequent transfer or re-allotment, the conveyance deed, the sanctioned building plan, the occupation certificate and the latest property tax receipts. Also ask for a no-dues confirmation from HSVP and the municipal corporation. A lawyer should trace the full chain and confirm there are no loans, disputes or pending family claims.
Can I buy just one floor of a house in Sector 21?
Yes. Independent floors are now common in Sector 21 and are sold with their own sale deed that should state the floor, the share of land and the parking allotted to you. Check that the building has an occupation certificate and that the number of floors matches what was permitted when it was built.
What is a collaboration deal on a Sector 21 plot?
It is an arrangement where a plot owner gives an old house to a builder, who demolishes it and builds new floors. The owner keeps one or more floors and the builder sells the rest. If you buy a floor in such a building, ask to see the collaboration agreement so you know who is responsible for defects and approvals.
Is buying an old house to rebuild a good idea in Sector 21?
It can be, especially if you want a layout no ready house offers. Plan for approvals, demolition, construction and a period of renting elsewhere while the work happens. Get an architect to confirm what the current building rules will let you build on that plot before you agree a price with the seller.
Are independent floors in Sector 21 easy to rent out?
Generally there is steady local demand from families who work in Faridabad and want a plotted sector rather than a society. Tenants look for lift access, stilt parking, power backup and a quiet street. Rental demand here is local in character, so treat rent as supporting income rather than the main reason to buy.
