What is a Penthouse? (And Who Owns the Terrace)
You are paying a large premium for a view and a terrace. One of those is definitely yours. The other may not be.
The short answer
A penthouse is the top-floor unit — usually larger, usually with a terrace, and always with a premium.
And here is the question nobody asks: IS THE TERRACE ACTUALLY YOURS?
Because in a great many Indian buildings, the terrace is COMMON AREA — belonging to all the owners — and it has been sold to the penthouse buyer anyway.
What a penthouse is
- Top floor of the building
- Usually larger than the units below
- Often a duplex, across the top two floors
- Usually with a terrace — sometimes a very large one
- Better views, more light, more privacy — no one above you
- A significant price premium, sometimes 30–50% over a comparable lower floor
The terrace question — and it is the whole page
Under most state Apartment Ownership Acts, and under RERA, the terrace of a building is ordinarily a COMMON AREA — it belongs to all the owners, jointly, in undivided shares.
The builder cannot simply sell it to one buyer.
And yet: “private terrace” is one of the commonest phrases in Indian penthouse marketing, and buyers pay a very large premium for it.
What actually happens, repeatedly:
1. The buyer pays a premium for a 'private terrace'.
2. The society is formed.
3. The society points out that the terrace is common area, and that all owners have rights over it.
4. A dispute begins. It can last years.
5. The penthouse owner discovers they paid lakhs for something the builder did not own.
The builder, by then, has gone.
How to check — before you pay the premium
1. THE DEED OF DECLARATION (or the equivalent under your state's Apartment Ownership Act).
This is the document that defines what is common area, what is limited common area, and what belongs to each apartment.
If the terrace is to be exclusively yours, it must be described as a LIMITED COMMON AREA appurtenant to your apartment — by name, in this document.
2. THE SALE DEED. Does it describe the terrace as part of what you are buying? In terms? With an area?
3. THE SANCTIONED PLAN and the RERA FILING. How is the terrace shown? What did the authority approve?
If the terrace is not expressly allocated to your unit in the Deed of Declaration, then a brochure calling it 'private' is worth nothing at all.
“Is this terrace a limited common area appurtenant to this apartment, and is it stated as such in the Deed of Declaration? May I see that clause?”
A builder who has done this properly will show you the clause immediately.
A builder who has not will change the subject, or explain that it is 'understood', or say that nobody has ever had a problem.
Both answers tell you what you need to know — and the second one is worth 30% of the price you were about to pay.
The other penthouse problems
- Heat. The top floor gets the sun on the roof, all day. Go at 4pm in May. Ask about the roof insulation, and whether it exists at all.
- Leaks. You are under the roof. Waterproofing fails, and when it does, it fails onto you. Visit after rain. Look at the ceiling.
- Water pressure. Top floor, longest pipe run. Check the pressure at 8am, when the whole building is showering.
- Lift dependence. When the lift fails, you have the most stairs.
- The premium may not survive resale. A 40% premium paid at launch is not necessarily a 40% premium at resale — the buyer pool for a large, expensive top-floor unit is small.
- Terrace maintenance. If the terrace is yours, so is its waterproofing — and it is protecting the building below you.
1. Go at 4pm on a hot day. Stand in the top-floor bedroom. Then decide what the view is worth.
2. Go after rain. Look at the ceilings. Look at the terrace. Look for stains.
Almost nobody does either. And a penthouse is the single unit in the building where both of these things go wrong first.
Frequently asked questions
What is a penthouse?
The top-floor unit of a building — usually larger, often a duplex, typically with a terrace, better views and more privacy, and a significant price premium of sometimes 30-50% over a comparable lower floor.
Is the penthouse terrace mine?
Often not — and this is the question nobody asks. Under most state Apartment Ownership Acts and under RERA, the terrace of a building is ordinarily COMMON AREA belonging to all owners jointly. The builder cannot simply sell it to one buyer. Yet 'private terrace' is one of the commonest phrases in penthouse marketing, and buyers pay a large premium for it.
How do I check if the terrace belongs to the penthouse?
Read three documents. The DEED OF DECLARATION — the terrace must be described as a LIMITED COMMON AREA appurtenant to your apartment, by name. The SALE DEED — does it describe the terrace as part of what you're buying, with an area? And the sanctioned plan and RERA filing. If the terrace isn't expressly allocated to your unit in the Deed of Declaration, a brochure calling it 'private' is worth nothing.
What are the problems with a penthouse?
Heat — the sun is on your roof all day; go at 4pm in May. Leaks — you are under the roof, and when waterproofing fails it fails onto you; visit after rain. Water pressure, since you're the longest pipe run. Lift dependence. And the premium may not survive resale, because the buyer pool for a large expensive top-floor unit is small.
What question should I ask about a penthouse terrace?
'Is this terrace a limited common area appurtenant to this apartment, and is it stated as such in the Deed of Declaration? May I see that clause?' A builder who has done it properly will show you the clause immediately. One who hasn't will change the subject — and that answer is worth 30% of the price you were about to pay.
